Low Carb Paleo Diets vs. Cancer: A Follow-up Note To Steve Jobs

Share:Tweet about this on TwitterShare on FacebookPin on PinterestShare on Google+Share on LinkedIn

“There’s no statistical significance in the sad passing of Steve Jobs and his choice of vegan diet.”

That’s a quote from one of the comments on the previous article about how Steve Jobs’ diet contributed to his early death (or at least it didn’t slow it down).  The article has received 64 comments, often from people saying there is no way his vegan diet could have contributed to cancer, or people saying that we have to accept that diet plays no role whatsoever.

As always, the best course of action is to look at the research.  Luckily, German researchers from the University Hospital of Würzburg just published one of the largest reviews on the benefits of low-carbs diets for cancer patients.

Published in the Journal of Nutrition and Metabolism, this large scale review would have been useful in helping to prevent Steve’s early demise.  Instead of following a low-carb diet, Mr. Jobs trusted his health to the Dean Ornish, high-carb, low-fat, macrobiotic, pseudo-vegan diet.  I’ve already discussed why this diet was terrible for treating cancer, but some of the readers were unconvinced.  At some least the vegans and vegetarians weren’t… (yet – this blog has transformed nearly 2 dozen former vegans back into powerful people full of more life than they had before…)

A vegan diet isn’t necessarily high-carb.  There has to be at least five or so vegans who live off of avocados and olive oil.  All jokes aside, the vast majority of vegans eat a high-carb, low-fat, grain based diet.  Even if you aren’t vegan, eating a high-carb diet is going to increase your risk of cancer.

The Study

The first sentence of the abstract reinforces how research has shown a high-carb diet diet is horrible for cancer patients.

“Over the last years, evidence has accumulated suggesting that by systematically reducing the amount of dietary carbohydrates (CHO) one could suppress, or at least delay, the emergence of cancer, and that proliferation of already existing tumor cells could be slowed down.”

By limiting carbohydrates, you can decrease your risk of cancer and improve your chances of recovery.  You can also slow down the progress of an existing cancer.

The researchers went even further to suggest a low-carb diet could be preventative against cancer.  So much for “no statistical evidence a vegan (ahem, high-carb) diet contributes to cancer.”

According to this review, a high-carb diet is believed to contribute to cancer in six ways:

1. Cancer cells depend almost exclusively on glucose. The mitochondria of cancer cells are dysfunctioning (because of UCP2), which prevents them from metabolizing ketone bodies or free fatty acids.  Chronically elevated glucose levels feed tumors and cancer cells.  Elevated insulin levels also promote the growth of tumors.

“Evidence exists that chronically elevated blood glucose, insulin and IGF1 levels facilitate tumorigenesis and worsen the outcome in cancer patients.”

The best way to fix this problem is to lower both glucose and insulin levels.  This method is especially effective in people with advanced stage cancer (like Steve Jobs).

“High fat, low CHO diets aim at accounting for these metabolic alterations. Studies conducted so far have shown that such diets are safe and likely beneficial, in particular for advanced stage cancer patients.”

2. High insulin and insulin like growth factor, “resulting from chronic ingestion of CHO-rich Western diet meals”, can “directly promote tumor cell proliferation via the insulin/IGF-1 signaling pathway.”  High insulin levels from a high-carb diet promote tumor growth.

3. Many cancer patients develop insulin resistance, which can make a high-carb diet deleterious to their health in numerous ways.  As the researchers stated, patients may “profit from an increased protein and fat intake.” (But they didn’t differentiate between good and bad proteins like we do in the Bulletproof Diet.)

4. High amounts of circulating glucose are extremely inflammatory.  Inflammation exacerbates almost all diseases, including cancer.

5. Rodent studies have found ketone bodies to inhibit cancer cell growth.  This has yet to be proven in humans – but the clinical observations are very strong.

6. A grain based diet contributes to inflammation, depletes nutrient stores, and prevents the absorption of nutrients.

Low-Carb Diets: Fasting Without Fasting (for cancer patients)

Caloric restriction is another effective way to lower both insulin and glucose levels, but it comes with some negative side effects.  Cancer patients often lose weight and become malnourished during their treatment, and starving them isn’t going to improve the situation.  Luckily, carbohydrate restriction can take advantage of almost all the benefits of caloric deprivation, without starving the patient.

“CHO restriction mimics the metabolic state of calorie restriction or – in the case of KDs (ketogenic diets) – fasting. The beneficial effects of calorie restriction and fasting on cancer risk and progression are well established. CHO restriction thus opens the possibility to target the same underlying mechanisms without the side-effects of hunger and weight loss.”

By cutting carbs (and adding MCT oil to enter ketosis faster), cancer patients might be able to utilize the benefits of caloric restriction, without cutting calories and suffering from malnourishment.  Speaking of malnourishment…

Grains Are Horrible Even on A Low-Carb Diet

The most interesting part of this study was the role grains played in causing cancer.  Vegans, vegetarians, and most Americans get the majority of their carbs from grains.  As the researchers pointed out, grain based carbs might be the main problem, not carbs in general.

A high-carb diet is bad for cancer patients, but a grain based diet is even worse.

“Usually, CHO restriction is not only limited to avoiding sugar and other high-GI foods, but also to a reduced intake of grains. Grains can induce inflammation in susceptible individuals due to their content of omega-6 fatty acids, lectins and gluten [159, 160]. In particular gluten might play a key role in the pathogenesis of auto-immune and inflammatory disorders and some malignant diseases.”

There are hundreds of reasons grains contribute to cancer, so this article will cover just a few.

Grains cause inflammation by themselves, regardless of whether or not the diet is low in carbohydrates.  This occurs through several pathways.

Grains contain omega-6 fats, lectins, phytates, damaging fiber, and gluten.  Anything that contributes to inflammation will make cancer worse, but gluten has several special characteristics that exacerbate cancer growth.  Gluten overstimulates the release of zonulin, a protein that regulates the space between epithelial cells in the small intestine.  This causes dysregulation between cells which promotes cancer growth throughout the digestive tract.

“In the small intestine, gluten triggers the release of zonulin, a protein that regulates the tight junctions between epithelial cells and therefore intestinal, but also blood-brain barrier function. Recent evidence suggests that overstimulation of zonulin in susceptible individuals could dysregulate intercellular communication promoting tumorigenesis at specific organ sites”

Reducing total carbohydrate load was not nearly as important as removing grain based carbohydrates.  It’s sad to think that Steve Jobs was being told to eat not only a high-carb diet, but also to eat 8-11 servings of “healthy” whole grains a day.

The study authors were quick to offer a solution: the paleo diet.  Both animal and human studies have shown the paleo diet is extremely effective at improving glucose tolerance and decreasing your risk for disease – far more so than the grain based Mediterranean diet.  Switching to a paleo diet would remove grains, and lower the total glycemic index of the person’s diet.   Vegetables have a far lower glycemic index than grains.  Studies have shown this results in better glucose control and less inflammation.

Paleolithic-type diets, that by definition exclude grain products, have been shown to improve glycemic control and cardiovascular risk factors more effectively than typically recommended low-fat diets rich in whole grains [162]. These diets are not necessarily very low CHO diets, but focus on replacing high-GI modern foods with fruits and vegetables, in this way reducing the total GL.”

Even if the diet was high in carbohydrates, it would be better than a low-carb, grain based diet. But none of them would touch the Bulletproof Diet, which also accounts for another major inflammation (and cancer) contributor: mycotoxins.

Cancer: A Novel (Neolithic) Problem

Cancer is a modern disease, and was almost unheard of before the agricultural revolution.  After switching from a high protein, high fat, moderate carb, low toxin diet to a grain based diet, people started getting cancer.

“Thus, the switch from the “caveman’s diet” consisting of fat, meat and only occasionally roots, berries and other sources of carbohydrate (CHO) to a nutrition dominated by easily digestible CHOs derived mainly from grains as staple food would have occurred too recently to induce major adoptions in our genes encoding the metabolic pathways.”

Humans aren’t made to eat a grain based diet.  I discuss this at length in the Better Baby Book, (Wiley, 2012!) and go into detail as how grains negatively effect epigenetics and our health.  Our genes are made to respond to certain foods both positively and negatively.  Cancer is a pretty negative response.

The researchers were smart to mention that diet isn’t the only factor in the development of cancer.  There are other components such as “regular physical activity, sun exposure, sufficient sleep, low chronic stress and the lack of foods that would also not have been available to our pre-neolithic ancestors.”  Okay, so diet was still the most important part.

Before you start ranting about how this only applies to high GI carbs and touting “complex carbs” and “healthy whole grains”, remember that whole grains have an equal or greater insulin response to white flour.  Regardless of the kind of grains you’re eating – they’re still going to produce a large insulin release.

The researchers go on to mention the importance of “sufficient vitamin D.”  This is particularly interesting since grains deplete vitamin D stores and interfere with vitamin D absorption.  There are even cases of people on a grain based diet developing rickets, despite adequate vitamin D intake.  Vitamin D deficiency is yet another pathway by which grains cause cancer.

Should Cancer Patients Go Zero Carb?

No.  As Dr. Paul Jaminet has pointed out, it’s important for cancer patients to avoid glucose deficiency.  Glycosolated proteins are needed for intracellular signaling, so too little glucose can disrupt this process.  Without enough glucose, these proteins can’t form efficiently.  When cells don’t communicate properly, cancer often ensues.  Ketogenic diets have had some success in treating cancer, though it’s not conclusive.  Keeping a small amount of carbohydrates in the diet (about 100g) would be the best option.

The Verdict: Low-Carb Paleo Beats Cancer

This study is one of the best showing a high-carb, grain based diet contributes to cancer.  It also shows a low-carb, paleo diet is an effective treatment for cancer.

Low-carb diets aren’t perfect for everyone.  They’re horrible for endurance athletes, and you shouldn’t eliminate all carbs for long periods of time. But low carb diets can be extremely effective in treating cancer.  Excess glucose feeds tumor cells, and insulin drives the overgrowth of cancerous tissue.  Grains are particularly disastrous as they also increase inflammation, deplete nutrient stores, and serve as a cheap source of carbs.  Reducing carbohydrates should have been one of the first things Steve Jobs tried, but instead it looks like he was advised to maintain a high-carb, low-fat, grain based diet.  I designed the Bulletproof Diet (moderate carb) to reduce my own chance of an early death, and make myself more resilient to cancer if it does strike. Plus, I like to feel good and have abs too.


What do you think of this study?  What are its strengths and limitations?  Lets discuss in the comments.

Some background research for this post may have been conducted by Bulletproof staff researchers.

  • What’s your thoughts on the Gerson Therapy? http://gerson.org/GersonTherapy/gersontherapy.htm

    I’m curious if you’ve ever looked into that? Similarities?

  • Leiv Hellebø

    “horrible for athletes”? Two Norwegian Elite series soccer teams are doing LC, the Swede Björn Ferry got an olympic gold medal on LC. Norwegian book about it with plenty of references to http://www.ncbi.nlm.nih.gov/ here http://www.lillemaane.no/bok/1130/Bj%F8rn+Ferry+og+Kenn+Hallstensen/Treningssuksess+med+lavkarbo

    • Its true that by lowering carbs and training in a fasted state you can increase your body’s ability to use fat for fuel at lower intensities. However, there is a ceiling at which your body will not be able to produce ATP from fat. Period.

      The studies showing an improvement or maintenance of performance on low carb diets were done with untrained subjects. This is completely irrelevant for highly trained athletes. People who go from sitting on their butt to training will always get better at first. Its called the novice effect.

      Most of the studies also did not have a high carb control group, which means they’re pretty useless.

      These studies often use walking as the control activity, which is totally pointless since walking always uses fat for fuel. No one walks there way to winning a triathlon or Crossfit competition.

      Not only is low carb during intense competition/training bad for performance, the massive amounts of cortisol you’ll be producing make it horrible for your health too.

      Just because a few soccer teams go low carb does not mean its optimal. I’d also love to see exactly how “low” carb they are eating during training and competition.

      Carb intake also depends on the sport. Some athletes can go lower than others, but for most sports its disastrous. You also have to define low carb as a gram amount before you can make a rational argument.

      Unless you can show exactly how many carbs Bjorn Ferry is eating, you can’t say a low carb diet is improving his performance. You also can’t say he wouldn’t do better on a higher carb diet.

      • Harmen Jeurink

        Swede Björn Ferry got an olympic gold medal on LC. Muscles burn fat very efficient. No problems with your cortisol levels: only if your body isn’t adapted to fat burning (which is the case with current western diet) excercise without glucose will raise your cortisol levels.

          slaughtered it’s way through central and eastern Europe. With plans to
          control the Black Sea, the Mongol Empire attacks the Roman Empire in
          what is now Turkey and Romania. But who is victorious? That, is for you

          invincible in there day.


          Mongolian cuisine refers to the local culinary
          traditions of Mongolia and Mongolian styled dishes. The extreme continental climate has affected the traditional diet, so the Mongolian cuisine primarily consists of dairy products, meat, and animal fats. Use of vegetables and spices is limited. Due to geographic proximity and deep historic ties with China and Russia, Mongolian cuisine is also influenced by Chinese and Russian cuisine.

      , Hi, from London England , I was brought up vegan and in the last two days after a year of illness and seeing our father die at 50 from throat cancer , he never smoked or drank I have ditched my vegan diet. Our dad had a period of stress where his weight went up from 12 stone to 16 and a half stone I am sure his eating of carbs in his diet fuelled this death , it has been very traumatic as he collapsed and died in front of us , was gone in 12 minutes Only two days off the vegan diet and I feel so different , more alive and full . You are right these diets with grains and high carb are cancer causing and are not a natural diet .

    I think a major issue with the veg spam is related to denial. People were given info from trusted (maybe even loved) sources. For example, I was a physic ed teacher that was educated by the food pyramid and chronic carrion models in college. I got extremely sick 2 years ago, and found a good doctor and did my research to find out that my entire college and working career was based on a scam. I have been on a slow road to recovery fuled by a diet that conforms to the bulletproof guidelines. This is another example of qualified/quantified research that supports the majority of the research data completed over the last few centuries (however, very contradictory to the reports and conclusions drawn from many of those same studies).

    “it’s important for cancer patients to avoid glucose deficiency. Glycosolated proteins are needed for intracellular signaling, so too little glucose can disrupt this process.”

    Ever heard of gluconeogenesis? That’s the process where the liver converts proteins to carbs to supply the body’s minimum requirements for carbohydrates, which is why as long as one takes adequate protein to maintain muscle mass, one can do just fine without dietary carbs. If Dr. Jaminet is totally ignorant of this basic process, then he needs to go back to med school biochemistry class.

    • Yes. I have heard of gluconeogenesis. There are problems that can arise on a long term low carb diet, and if someone is dying of cancer, its best not to stress on of their most important organs: their liver.

        The authors of this study
        concluded that Mongolia’s low breast cancer incidence is of particular interest
        because of their unusual diet (primarily red meat and dairy) compared with
        other Asian countries. More intensive study of potential dietary, reproductive
        and lifestyle factors in Mongolia with comparison to other Asian populations
        may provide more clarity in what drives the international breast cancer rate

          Also rural chinese women who have a practically vegan diet have a rate of breast cancer of about 1 in 100,000. Ever heard of The China Study?

          “……though the Mongolians have a low rate of breast cancer, they have very high rates of other cancers like liver cancer.”

          Glen, the main pathogenetic factor of all those cancers you mentioned is high prevalence of oncogenic INFECTIONS, eg. HBV, HCV, HPV, HP due to excellent conditions for their transmission (overcrowded living conditions, poor hygiene, …).

      You should read the whole discussion before dismissing what Paul Jaminet has to say on the subject. He covers why gluconeogenesis is not sufficient in his view.

    I have been both vegan and paleo and can say that the latter has left me feeling very healthy and fit. I am a distance runner and was skeptical of continue my training without the high carb diet I had always been advised to follow. What I’ve learned through research and self-experimentation is that the source of carbs is far more important that the amount. I get all of my carbs from fruits and veggies and increase my intake during competition. Works wonders for me and my performance continues to increase as does my muscle mass. My vegan friends eats grains without regard and I they all have excess stomach fat and digestion problems.

    When someone is selling something, they have an incentive to distort facts. I saw now peer review evidnce or statements, and only an interpretation by profit motivated authors of a study done in germany. The conclusions seem a bit tooo total and it is hard to see how they were arrived at, when a study is paraphrased

    • Did you even read the article? There were about 15 peer reviews studies, and they didn’t profit in any way from saying grains were bad for you. You’re blaming something on “profit” when this has absolutely nothing to do with it. Maybe you should click on the link in the text and read the study yourself.

  • Space

    I’ve been vegan for a few weeks and my diet is certainly not “high-carb” or “grain-based”. So I find the beginning of this article very misleading, to say the least.
    Grains are just 1 of the vegan food groups, the others being legumes, nuts and seeds, fungi and vegetables.
    There’s also plenty of vegan food supplements available, and none of the ones I found are based on grain carbs.

    • Dave Asprey

      If you’re vegan, you are eating mostly carbs by definition. Broccoli is mostly carbs too, just not starch. Legumes are nearly as toxic as grains…unless they’re carefully fermented, which brings its own set of risks. Nuts and seeds are high in omega 6, one of the primary vegan problems. (omega 6 mask cellular energy problems for a while). Fungi are medicinally useful, but nutritionally questionable for a variety of reasons, especially smooth cell proliferation caused by garden variety mushrooms. They also feed fungal infections.

      Thomas Jefferson loved to garden and said meat should be eaten sparingly as if a seasoning. lived to be a hundred. low carb made me feel great and keep my blood sugar down. i count net carbs and adjust 100 to 200g per day as needed. I eat everything. but mostly veggies and haven’t felt this good in years. low carb has to be the key.

    Love the work that you guys are doing. However, I’m a little concerned about the Upgraded whey powder. My wife is a coeliac and over the years I have been trained to read labels. It states that there is maltodextrin in the product which from my understanding contains gluten. Could you please advise on this?

    • Dave Asprey

      Maltodextrin does not contain gluten! (I wouldn’t eat it if it did – gluten does bad things to me.) From http://www.glutenfreeliving.com/ingredient.php :
      Maltodextrin is gluten free. It can be made from a variety of starches, including corn, potato, rice or wheat. However the source does not matter because maltodextrin is such a highly processed ingredient that the protein is removed, rendering it gluten free. If wheat is used to make maltodextrin, “wheat” will be appear on the label. Even in this case, the maltodextrin would be gluten free.
      In our case, it’s corn based. I don’t like that either, as some people are sensitive to corn. Even *most* of those people can tolerate highly purified maltodextrin. However, it would be great to find a maltodextrin-free version of the MCT powder, but extensive searches around the planet found exactly none available unless I open a new factory to make it from scratch. (that’s a multiple million dollar cost)
      Until then, Upgraded Whey is as safe as I know how to make it. ?

And they seem to life long and healthy lifes as well, if you consider the harsh and demanding lifestyle.

    Any thoughts on this?


    • Dave Asprey

      Bren, sorry to hear about your dad. The study from ncbi wasn’t about high protein specifically. They used some trickery in it. The lowest p-value was from grains and potatoes and breads; that means that they were most statistically predictive, although the incidence was higher for meat eaters, it was less predictive (but still predictive).
      The real trickery came when they looked at overall protein intake to point the smoking gun. To calculate macronutrient protein intake, you take red meat protein, and mix it with gluten and soy intake to get “total protein.” So what you’re seeing is not a study that shows meat caused this problem, you’re seeing a study that says a mix of proteins, some toxic, some not, is implicated.
      But even worse, mycotoxins and omega 6 oils and likely heavy metals were present in virtually all of the meat consumed by these participants. Industrial meat is bad for you; I don’t eat it. Avoiding all meat – even grass-fed – because of studies like this won’t help you avoid cancer; it will probably contribute to cancer because you’ll miss out on vital fats and nutrients, and you’ll eat too many omega 6 oils and carbs.

      • Bren

        Thanks so much for your reply Dave! Very helpful! I found your website as I was looking for a different way to eat. I typically eat lots of grains and have a very high carb, low fat, low protein diet. I crave sugar! I’m 50 yrs old now so I imagine it’s normal to have less energy but I am ALWAYS tired and sluggish. I went to the doctor for my check up, lab work etc. and got a clean bill of health. When I began reading about the benefits of a high protein, low carb diet it sounded like something I could try but I was concerned about the link to cancer. Thank you for explaining that to me.
        I decided about 2 days ago that I would start a new way of eating by first cutting sugar out of my diet. Today I feel horrible! I’m more tired and sluggish and just feel like I have bricks in my shoes! I’m not sure if I should continue this course or if this sluggishness will subside soon. I’m always tired but not this bad! lol
        I will continue reading your website and hopefully will be able to change at least a few things in my diet that will result in more energy
        Thanks again!


        • Dave Asprey

          A high fat, moderate protein, low carb diet is better than a high protein low carb diet!
          It’s normal to feel tired as your body adjusts to fat burning mode. They call it “carb flu” and it lasts a few days, then you wake up feeling like a new person. L glutamine will help you feel better as you adjust!

        • Bren

          So it’s been a few days since I took some baby steps closer to eating a high fat, moderate protein and low carb diet. Problem: it’s hard to eat a high fat diet when you’re eating low carbs! At least for me. 🙂 Today I ate oatmeal with lots of butter and a little milk, then for lunch I ate an avocado with about 3/4 can of tuna and I had the hardest time finishing it…I am stuffed and my appetite is decreasing. That’s a good thing for me but is this normal? By the way, the L glutamine really helped! I’m going to try your coffee, butter and MCT oil soon. Thanks for your website and help, it is much appreciated! 🙂


        • Dave Asprey

          It’s normal for appetite to fall on higher fat diets; that’s the effect of leptin levels. No need to stuff yourself, but do not try to limit total calories. Trust your body to eat what it needs.

        • bren

          I’ve been trying to follow the Bulletproof diet (and the Jaminet/Ching) and succeeding most of the time. I’m feeling pretty good but missing the variety I once had in my diet. I have a cup of bulletproof coffee in the morning then I usually have some Noosa yogurt or eggs with spinach or some other veggie. Lunch is avocado, salad, meat or fish with a little rice or sweet potato and maybe some fruit. Dinner is usually the same as lunch. Any suggestions for adding some variety? Maybe I’m just craving the pasta, bread and cereal that I used to live off of!
          Thanks for your website!

          I don’t eat cow milk because it’s not paleo and I think casein is the devil (second only to gluten). I highly recommend hemp milk. Hemp milk has 4:1 ratio of fats to carbs/protein and is a great way to increase your total fat count. Do the rest with fatty fish & meat (grass fed!), avocados, nuts, healthy oils, and you can up the fat content of your diet a great amount.

    The next celebrity dying of an excess of trust in WesternBuddhistVeganSyndrome … what a shame ….

    • Dave Asprey

      It would be a mistake to confuse Buddhism and veganism. Buddhists aren’t vegans ever historically although the warm, low altitude ones are vegetarian. If I had cancer, I’d definitely be talking with Tibetan doctors as a part of my healing team, some of the pulse analysis stuff they do is pretty amazing. But vegan diets for cancer? Bleah.

      • Mike

        Right. I was referring to Western Buddhists, a very recent breed, for whom the Dalai Lama (his jet-setting, his cancer treatments) may be the best possible symbol …

        • True that. In fact, actual Tibetans eat a high fat/ high protein diet in order to tolerate the altitude.

          yeap, there’s even several people who’ve returned from Tibet in awe of the fact that monks eat meat, not all, but a lot, and their spiritual take on the act is very balanced, they’ll say “one life feeds many”, referring to a cow, as oppose to chicken or fish. They understand the principles of life and death. Some vegans are so hardcore dogmatic that they end up disconnecting from the very nature they were trying to protect in the first place.

          Hi, what a great forum this is and I want to applaud the help that was rendered to my father by Mr. Rick Simpson. I send my love and prayers to all who have come here for help. I’d like to request a prayer for Mr. Rick Simpson who have cured my dad of his lung cancer. He was diagnosed about 3 year ago, beat it once and then a few months later it came back in his brain. He has been doing everything he possibly can, medication wise, and now the cancer seems to be immune to chemotherapy and radiation. He talks about this being his last year of life, so I feel like he has lost hope. after several online search, I found Mr. Rick Simpson Cannabis oil which we secured via: ricksimpsonmedicals@gmail.com, as soon my dad started his treatment and to God be the glory I didn’t lose my daddy to lungs cancer anymore.
          Please help me share this testimony to the world at large as my dad has been saved by Mr. Rick Simpson Cannabis Oil which we order via: ricksimpsonmedicals@gmail.com. My dad is now the strongest person I know and this cancer has has been cured. Am now seeing my dad thriving and full of life again. I admire his personality so much. Once again, God bless Mr. Rick Simpson and all who have reached out for help on here. With love,
          share my story to the world and tell everyone to contact Mr. Rick Simpson on: ricksimpsonmedicals@gmail.com

    the macrobiotic whole grain based diet is the only
    way to naturally cure cancer, heart disease, diabetes,
    and all the other “incurable” illnesses.
    whole grains are the very basis of our diet. whole grains,
    beans, and most vegetables are the center of our daily food.
    we should eat at least 50% whole grains. the longest lived
    and healthiest people on the planet are the okinawans. they
    eat a whole grain based diet, as do the rural japanese.

      Whole grain worship is delicious, but it destroys your health. The biochemical reactions are well understood, and historical societies that added grain got shorter, fatter, and deformed. Bread tastes good but isn’t food for humans.

      • Manny

        Hi Dave, I dont think you answered the question on the Okinawans who lived 110 years and ate mostly grains by weight, balanced with exercise, fish and vegies. Their cancer rates way lower than most americans. Please explain how they ate so many grains and still had ultra low cancer rates and lived to 110

        • LCforevah

          Manny, I just went to that wiki source you provided and it’s obvious you did not read it! The only grain source cited is white rice, of which the Okinawans eat 3/4 the quantity of other Japanese…. the other carb source is… sweet potato! They eat pork and fish and cook in lard, which is pork fat if you didn’t know! Yellow and green veggies. They eat more soy than we do but in the end, it’s only 6% of their diet. Okinawans have a tradition of eating to only being 80% full, caloric restriction which extends life, is already part of their culture.

          Their longevity is about a spiritual outlook and social network not found in modern societies. Elderly women are the spiritual leaders in Okinawan society. Elderly Okinawan women have the lowest suicide rate of all of eastern Asia. They have friendship networks that start in childhood and continue through to their centenarian lives, that’s for both men and women.


          Manny, do better research.

        • Artur Denysenko

          Are you blind?
          “… However, pork was primarily eaten on holidays, and the daily diet was mainly plant based.[5] Their overall traditional diet would be considered a very-high-carbohydrate diet by modern standards, with carbohydrates, protein, and fat providing 85%, 9% and 6% of total calories respectively.[6] The consumption of pork in Okinawa in 1979 was 7.9 kg (17 lb) per person per year”

        • Ferns

          No, you seem to be the blind one here, dear. LCforevah just made the
          distinction between the consumption of grain vs. root, he never wrote anything about low-carb vs. high-carb

    At 27:00 of the presentation:
    “We are starting to understand it matters what you eat. …It matter where your calories come from…. We now have good evidence in model organisms. If you overfeed someone with fat you don’t increase their cancer risk at all. You overfeed somebody with carbohydrates and you dramatically increase their cancer rate and protein is halfway in between. And that is why we are going to have a huge debate about these carbohydrate based diets.”

    I was on a vegan diet for about 2 years (my boyfriend now husband is vegan. He was cute. I was in love…) I developed chronic fatigue syndrome (the really severe myalgic encephalomyelitis “sub-type,” not the CFS some folks get diagnosed with for simply being a little sluggish or because they have a gluten allergy), severe neurological and mitochondrial problems, immune issues, and thyroid cancer. I was bed-bound for five months and had to use a wheelchair (although many days I wasn’t well enough to even sit in a wheelchair). I’ve been eating a high-fat, moderate protein paleo diet for about three months, with a good amount of green veggies and very little fruit (half an apple a day, sometimes some berries). My neurological symptoms were reduced by 50% in the first week and disappeared entirely after the first month. In this last week I can say that I am at 90% of normal and convinced I’m on my way to a full recovery. I think some people can tolerate a vegan diet better than others. I have a sensitive brain, and my vegan diet just wasn’t good for my CNS or my immune system. My husband, having witnessed my experience, is starting to eat small amounts of meat again and has stopped being afraid of fat. I may still end up losing my thyroid, though. In the end, it wasn’t worth it, but I’ve learned the importance of listening to my body and really interrogating the evidence. I felt, long before I got sick, that I didn’t have the same level of energy or resilience that I used to have, and that my brain was permanently foggy, slow, or underpowered. I was 28 and I told myself that I was just getting older…never occurred to me that it was my diet! Now, when I eat a super fatty piece of meat, my brain lights up like a light bulb.

    • Laura

      What’s your blood type out of curiosity? I have a friend who is following the blood type diet, although there has been no scientific proof that it’s legit, I’m just curious to know what your blood type is… type O’s are supposed to thrive on meat while type A’s thrive on a more vegetarian diet…

      • Carelyn

        But … I am blood type A and stayed pretty strictly on the Eat Right 4 Your Type Diet most of the time for about 8 years, in conjunction with the Zone Diet (which is 30% protein, 30% fat, and 40% carbs). Every time I went off this, I felt lousy. Back on it, I felt better than I ever did when I was 20 years younger. Twice now I have tried a vegan diet, still sticking with the ER4YT guidelines, and, both times, it has been a disaster for my energy levels. Initially, I lost some weight and had high energy. Then, gradually, I got depressed and extremely tired and de-motivated. This is in spite of good quality supplements, organic foods, pure water, etc, etc. This last time I have stayed on the vegan diet for about 2-1/2 months but today resolved to never do this again. It just does not work for me at all. I avoid gluten, so it’s not that. I am going to do the Bulletproof Diet and will report back on how it goes. My instinct is that I should have stuck with my own instincts about what I need and not get talked into the vegan diet in the first place.

      yes and it’s been confirmed many times since that eggs spread cancer by large high quality studies that expected to find nothing in line with their mainstream beliefs. These people are such liars and they have real human blood on their hands as well as animal blood. I simply don’t understand where all this low carb “paleo” nonsense comes from. Paleo man never ate low carb at all except when there was none available, every primate prefers fruit. Paleo man HATED animal protein except when it was the last resort. Some of these people are clearly deranged individuals. I mean look at the last header “The verdict: low carb improves cancer”… if this were a parody blog post of a crazy so-called “paleo” individual I would say this part is too strong, too ridiculous and too utterly insane.

          have you been munching those mushrooms again? Your brain has become addled with plaque from too much flesh in your daily scoff.

          STAY AWAY FROM THE FLESH is the basic message if it’s too long an article for you. Unless you fancy an early night on the slab.

        • Keith Taylor

          You have the wrong guy: I’m a MEAT eater, not a mushroom eater … but you wouldn’t know the difference, not having experience with the former.
          I told you at our first meeting during the aurochs incident and, since you have forgotten, I’ll tell you again: MEATIVORES EAT VEGGIEVORES.
          I won’t stay away from flesh … hell, I’ve even found myself being guilty of enjoying indulging in the SINS of the flesh AND, to top it all, I’m unrepentant about it.
          Now go away and play with your peanuts … and leave me to enjoy my meat.

        • Shiprex

          It was you who had the wrong guy. I wan’t around in the time of Aurochs and have evolved since then to have command of the ability to choose. It’s called consciousness and this leads the inquisitive human mind to discover things about the place we live in and how we are not CARNIVORES but some choose to be CARNIST because it is a conscious choice like a TERRORIST chooses to carry out acts of terror or RAPIST carries out acts of rape. .

          Since you seem to know so little about things I can enlighten you.

          Human jaws closely resemble those of FRUIT eating mammals or FRUGIVORE that they may munch down on the odd beetle, worm, ant or rat doesn’t make them an OMNIVORE you carnists keep screaming about being.

          CARNIVORES have vastly different jaws that look and operate very differently (perhaps this is a reason the the flesh diet of modern Western cultures has such a high instance of diet related disease).

          Human digestive tract length is more like those of HERBIVORES (completely plant eating organisms) when compared to overall size. The CARNIVORE has a much shorter length because of how flesh rots quickly (perhaps this is a reason the the flesh diet of modern Western cultures has such a high instance of diet related disease).

          Human digestive secretions match more closely those of herbivores and frugivores throughout the digestive process.

          Shout and scream about how you are trying to be natural to your inner caveman but that is like the bible, a story made up by man. Early humans most likely foraged for fruit and plants long before they thought of running after deer, cows, pigs and even chickens (all of whom would out run any human not to mention the effort expended in doing this would outstrip that gained from actually catching and killing it which is another they didn’t have free medical care in caveman days to deal with the undoubted clashes with horned deer, cows or even pigs so chances are humans would either have scoffed the leftovers from actual carnivores (i.e. roadkill) or taken out the sick or injured (more risky job than just munching on the fruits and berries all round you in the first place.

          So in conclusion you are not a MEATIVORE or a CARNIVORE you are a wannabe who never could be because you likely don’t eat flesh raw. That’s natural.

Yes he was strick on Paleo because he had Celiac so avoiding grains was not a problem. People make me sick.

    • paleogal

      The Aussie who documented his journey in “Fat, Sick and Nearly Dead” avoided all grains. He only consumed fruits and veg. His health was severely compromised requiring drastic measures – not something most people who go Paleo would have to contend with.

      • Padraig

        Anecdotal examples of one person this or another person that are all you have to base things on while large epidemiological studies following hundreds of thousands of people all showing that cancer risk goes up almost linearly with animal consumption are ignored, it’s ridiculous. Sure you won’t get cancer like average joe with his drinking, burgers, chips, possibly tobacco and heavily processed foods etc., that’s hardly something to write home about.

        Also “paleo man” would have rather stuck sharp flints in his eyeballs than eat animal protein over fresh, tasty fruit. Paleo man only (barely) survived with a high amount of animal protein because guess what? There was nothing else. The neanderthals who ate even more animal protein for all intents and purposees went extinct (there are indications of a small percentage of crossbreeding with modern humans). Paleo man HATED animal protein except when he was starving and there was nothing else. The paleolithic era last a long time, however it was only towards the end of it that man started eating a high animal protein diet. It’s all the blink of an evolutionary eye compared to our great ape ancestry. What you “paleo” are claiming is counter to evolution and to common sense.

        • dave

          Padraig, not sure where you are getting that “paleo man” hated meat BS. Untrue. There is no proof anywhere that shows that. Hell, man has been running buffalo off cliffs for hundreds of thousands of years and eating them. Stop making stuff up.

        • disqus_ax7qut9jL1

          Complete and utter nonsense. Wartime Europe’s deprived and hungry populations craved meat over anything else, it’s human nature to seek the most nutrient and energy dense foods, properly raised animals, vegetables and fruits are lightyears ahead grains.

          You’ll need a stronger argument to go head to head with Weston A Price and his book Nutrition & Physical Degeneration. He visited dozens of primitive populations of supreme health across the globe. They all had different completely different diets but there were consistencies across all of them. None of them ate grains, vegetable oils or processed, sugared junk. Without exception, NONE of them were vegetarian!

          Maybe you’ve misinterpreted the hated animal protein, I’ve read many places that traditionally organ meats and fatty cuts were far more highly prized than lean fillet steaks which were fed to the dogs.

          Those tribespeople weren’t some hippie, cow hugging nation with ideas to influence what their people ate based on morals, ethics or self-righteous crap, they ate what gave them and their forefathers strength, health & vitality for countless generations. No national schooling where food industry lobbyists influence on national guidelines affects curriculum and school dinners, just what great grandmother was told by her great grandmother was told by her great grandmother! Their main goal, survive in the real world, that’s a place you wouldn’t stand a chance unless you evolve a few more stomachs to ferment grass!

          High fat, low carb paleo all the way 🙂

        • R L

          “Without exception, NONE of them were vegetarian!”

          That is inaccurate to the point of lying. Numerous NIH studies, and others, have shown that Seventh-day Adventists who are mostly vegetarian live 15-20% longer than the U.S. population as a whole. Contrary to the self-serving “studies” mentioned in this article, the NIH studies go back decades.

        • disqus_ax7qut9jL1

          No, that is not inaccurate. As my comment clearly mentions I’m referring to the primitive folk studied by Weston A Price. In the exceptionally healthy cohorts there was a range of diets, however NONE of them were vegetarian!! Read it.

          Unlike the typical NIH study, Weston A Price set out to answer an extremely difficult question. He had no prior bias or hypothesis to prove or disprove, he had no sponsorship from any expectant donors. This allowed him to be completely objective.

          Unlike your typical NIH study, in which a sponsor funds the study who clearly want something in return. Scientist claim impartiality, but they’re not stupid, they know that if their work tramples on the sponsors’ agendas then the funds will dry up and they’d be lucky to have a career.

          Just look at the recent news about Coca Cola funding fake studies to further their BS obesity/health nonsense. Liars just like your Ancel Keys conduct many of your treasured NIH studies sponsored by death machines like Coca Cola.

        • R L

          The Adventist Health Study conducted by NIH was not sponsored by the group or individuals being studied. It was solely funded by NIH.

        • disqus_ax7qut9jL1

          Yes, and who funds the NIH? Besides you choose the Seventh Day Adventists in isolation.

          For starters only 30% of them practice some form of vegetarianism (compared to 3% of Americans), but their diet is not the only thing that sets them apart from “typical” Americans. Doubtless they eat more plants than the average American, but I’m not suggesting a carnivorous diet is the healthiest.

          They are typically physically active and almost none of them smoke! They also have faith in God, many of these long lived SDAs put their health and longevity down to faith more than anything!

          So how do you answer that RL?

        • R L

          I agree that a healthy lifestyle is a complete package. No one can do just one thing and be assured of good health, except maybe avoiding harmful substances, such as tobacco.
          And I don’t think it is necessary to be 100% vegetarian or vegan. I do question your percentage of vegetarian SDAs, but I don’t want to stay on that subject.
          I agree that it is possible to eat too much of any single type of food. Like the President of the potato association who ate nothing but potatoes for 90 days. Or the idiot that ate nothing but McDonalds for 30 days. I think we need balance including a reasonable quantity of everything good but not a concentration of any one thing.
          If it is possible to raise your own grass fed cattle, I believe beef, in moderation, can be good. How to find that when you don’t raise it yourself is a different problem. But moderation is the key. Not an entire meal of only one type of food and not an emphasis on protein over carbs. Just my opinion and my personal experience.
          I’m not a scientist or an expert. My grandparents, parents, and many friends have been or are vegetarian. It didn’t help my father who died of Alzheimers at 82 but my mother is 94 and still going strong with no health issues whatsoever. My grandmother had 11 brothers and sisters who ate, drank, and smoked whatever they wanted and died of heart issues in their 60s. She, being vegetarian, died of heart issues in her mid-80s so her lifestyle bought her about 20 years.
          On the other hand, my brother who almost never ate meat, died of colon cancer at 65, so one point for your theory. But I still like the balanced approach.

        • disqus_ax7qut9jL1

          That’s a more rounded argument, I’ll give you that. I think one thing is clear, you can only “influence” life’s outcomes. By that I don’t mean that your future is written in the stars (or your genes). I just mean there are so many factor beyond our control or that we are ignorant to, both as individuals and as a species.

          These days environmental toxins are everywhere. On a cold morning, when the wind is coming from the airport I can smell the plane fumes from over a mile away. Sadly there’s nothing I can do to avoid this, wearing a gas mask to work is akin to wearing a tin foil hat in most peoples opinion.

          I think variety puts a better perspective on balance than moderation. Everything in moderation is a ridiculous statement. For starters a “moderate” amount of different substances is vastly different. e.g. a moderate amount of vegetable oil (highly toxic industrial filth) would be considerably larger in volume to a moderate amount of uranium-235. There’s little doubt too much of a good thing is bad for you. But with that in mind I wouldn’t recommend people smoke in moderation, or wear their seat belt in the car with moderation, or wash their hands after a post-mortem examination prior to delivering a baby with moderation. Some things should not be done only in moderation but with extremism!

          Anyway regarding your opinion on beef, I whole heartedly agree with you. All animals should be treated as nature intended not only for their wellbeing but our wellbeing too. Most people understand you are what you eat, and the same goes for the plants and animals, they are made from the constituents in their diet/soil. Sadly many people have no concept of the food chain as a CHAIN, you’re not just what you eat, but what your meal ate, and what it’s meal before it ate, the same goes through generations too. The it matters not just what the cow you actually ate, ate, but also what’s mother ate, and her mother before that. With that in mind you can imagine how unfriendly toxins can infiltrate you liver regardless of whether you eat meat or not. This food chain perspective does hint as to why pant sources are likely to be cleaner and healthier than meat, but doesn’t guarantee it.

          My personal experience proves I, and others around me, do far better on a grain free, vegetable oil free, zero sugar diet.

    Dear Dave, as per in the BBC documentary (http://www.bbc.co.uk/news/health-19112549 doctor) (quote the article) “according to ongoing research by Professor Valter Longo … there is now evidence suggesting that IGF-1 levels can be lowered by what you eat. Studies on calorie restrictors suggest that eating less helps, but it is not enough As well as cutting calories you have to cut your protein intake. Not entirely – that would be a very bad idea. It’s about
    sticking to recommended guidelines, something most of us fail to do.”

    Do you agree with that?

    I read you said time to time that protein restriction is good (but I could not find any specific post yet), plus The Bulletproof Diet prescribes only 20%of energy coming from proteins.

    Are your IGF-1 levels low or high?

    A vegan diet does not mean a high carb, grain based diet! It is too simplistic to say a vegan diet itself caused anything. The actual foods eaten must be examined in all cases and also any other factors that may have contributed. There are unhealthy vegans just like there are unhealthy meat eaters. If the vegan diet is varied, with lots of vegetables, some fruit and focuses on unprocessed foods (as all diets should be) and also includes healthy fats, sprouted/soaked nuts, seeds and legumes with very limited sprouted, selective grains…it is the healthiest diet around. Meat/dairy are inflammatory. The production of meat/dairy is bad for the environment, the economy, the poor animals that suffer and most of all bad for your body. Meat and dairy are nutritionally inferior to what is available in a plant based diet. This is easy to see on any nutritional analysis…meat and dairy don’t measure anywhere near the vast nutrients both macro and micro in vegetables and fruits.

    • Meat and dairy are not inflammatory. Unless they are. Grains and nuts are not inflammatory, unless they are. It is our reaction to those foods that is inflammatory, or not. With natural grains, nuts and natural meats, inflammatory rates are lower than with bred, GMO and processed grains, nuts and meats. But in either group, grains are more inflammatory than meats.

      Before you accept the vegan model as supremely healthy, look at the data on the long term affects of veganism on the human brain. Even the adult human brain has higher risks on a vegan diet. With children, it is far worse due to their extreme growth requirements.

      Too many people compare apples to armadillos with the anti-vegan and anti-paleo polemics. Just because eating bad meat has bad effects does not mean that eating good meat cannot have good effects. Yet that is the standard argument. Very few people think that the health effects of eating processed foods reflects on eating raw and un-processed foods. But they do not apply the same standard to meat.

  • Shelly

    Ugh people get cancer and die. It sucks and its sad. Exercise, eat right(whatever that means for you) and avoid highly processed foods, vegan or otherwise. There are other factors at play such as genetics and environment. Honestly I think vegan, vegetarian and paleo are the only reasonable diets out there. I’m vegan btw. Sorry to hear that some people have had a negative experience with following a vegan diet, but that could be because you were not focused on the nutritional aspects, but rather focused on simply eating vegan food(Oreo cookies are vegan). Since I switched to eating a plant based diet I have felt a lot better, I sleep better, have no tummy problems(I was beginning to have gallbladder issues among other things), less headaches. And I go for a full physical yearly so I know I am getting the nutrients I need.

    • Shelly

      Don’t take food advice from anyone other than an MD. When I googled cancer causing grains the only people are found were people claiming to be nutrition experts despite the fact that they were trained as dentists or psychologists. If I learned anything from college it’s that statistics and scientific data can be misleading if you don’t know what you are looking at.

It’s just a LOT harder for most people to do it healthily than than the HF/LC way, and that’s coming from a lifelong vegetarian. My diet was always “healthy grain based” and I’ve always eaten lots of “healthy” whole grains, legumes, vegetables (okay that took me until my early twenties), nuts, and fruit. Most people who spent a lot of time around me called my diet “healthy.” Cheese and yogurt were fairly common in my diet, and I’d eat fish and eggs occasionally. Apart from periods of depression, my calorie intake was always between 1300-2000/day with a reasonably active lifestyle. Yet a few months ago, I found myself, at thirty years old, feeling like I was on the brink of death. I was short of breath all the time, having chest pains and dizzy spells, and eighty pounds overweight. I had severe knee pain that made it difficult for me to get up and down stairs, which was awfully inconvenient since my apartment is on the second floor and my office is in the basement of a 100 year old building. I explored veganism and juicing, but, despite my enthusiasm after watching all of the gimmicky documentaries, I was ALWAYS hungry and tired and miserable. I worked out several days a week for anywhere from one to three hours at a time. None of it was making a difference. I found Wheat Belly and Bulletproof and started looking into more and more about carb reduction and health. After one week giving up wheat (JUST wheat), I lost seven pounds and didn’t have joint pain anymore. I’ve been following a semi-strict (I occasionally eat chips at Mexican restaurants, knowing I’m going to pay the price) Bulletproof diet, using the coffee and intermittent fasting, for about five weeks. I’ve lost twenty pounds and I feel like I’ve lost fifty. I haven’t been to the gym once and my muscle tone is improving. Bowel movements have gone from having diarrhea 5+ times a day to one nice solid movement first thing every morning, like clockwork. To any health-conscious vegetarians out there (as opposed to animal ethicists, which is a totally different life choice), if you are considering giving this lifestyle a try, go for it. If you are eating what you’ve been told is a healthy diet, but you’re still fat and feel like crap, chances are, your “healthy whole grains” are killing you.

      • This is poor advice. The opposite is true. Never take food advice from an MD. They are almost completely ignorant of the scientific literature on food, are not taught it in medical school, and only know what they pick up from JAMA and mandatory medical education conferences that are funded by drug companies.

        Right on about the misleadingness of statistics and scientific data. In fact, there is a new trend to allow “scientific” conclusions in peer-reviewed papers that are unsupported by the evidence presented in the papers. Somebody else mentioned the China Study, which is a good example of reaching a conclusion by statistical means from flawed data, and then stating it as a conclusion before it is validated by a controlled study. So far they have yet to be right. Caveat emptor.

        • Padraig

          I don’t know about “never take advice from an MD”, some alternative medicine practioners are MDs and have in a way “seen it all”. However if there’s an MD or “Dr.” in front of the name I will know not to take them seriously until they prove they they can be because they have the clown label on them.

        • ab

          I was diagnosed with Testicular cancer about 25 years ago. After an orchiectomy (removal of a testicle) Doctors all recommended that I get another surgery (Never ask a barber if you need a hair cut). The risks no surgery and a 25% chance that I still have cancer and 75% I don’t. The surgery called a retroperitoneal lymph node dissection is not pretty and can leave you impotent and sterile.

          I opted against their advice to go under a monitoring protocol and 25 years later I’m cancer free and have 2 wonderful children.

          Always look out for yourself and never fully trust a doctor, always check on them.

  • AcaciaG

    Steve’s cancer had been developing since he was in his 20’s. By the time he was diagnosed with cancer, it was already in it’s later stages, so really, there was nothing that could have been done to save him. His diet would have only prolonged his life if anything. This article is a complete pile of garbage. High-carb, low-fat vegan is the best chance you have against cancer. No questions asked. Anyone who thinks otherwise should read The China Study (based on over 20 years of SCIENTIFIC RESEARCH) or check out some of John. McDougall’s lectures. It’s funny how the author here is stating that a low-carb (restrictive) diet is great for health both nutritionally and defending the body against cancer, but that a high-carb vegan diet depletes the body of nutrients. Then, he states that the paleo diet is best for cancer patients. Are you kidding me? Sure, loading the body up with rancid animal proteins (which feed cancer cells) sure seems like the way to go! Cancer patients have poor immune systems, so restricting nutritional intake will only make matters worse. How could loading up the body with nutritional whole foods (fruits, vegetables, grains, legumes, seeds and nuts) possibly INCREASE your cancer risk? What a load of bull! And don’t even get me started on diabetes. McDougall, Fuhrnam, Ornish, Barnard and Campbell have been REVERSING diet-onset diabetes for years. How many doctors have managed to do the same by encouraging low-carb/paleo diets and prescribing medication that only makes the condition worse an ensures a lifetime of battling the so-called disease?

    • The scientific research of the China Study may seem good to you, but I think it is crap. The team behind it has not been right once (!) when their conclusions were tested by experiment. Every time, their conclusions were 100% statistical and not actually applicable to reality.

      Nuts add omega-6 polyunsaturated fatty acids to the diet, which is a known cancer risk. So is carb overconsumption that leads to insulin resistance, regardless of whether it is vegan, paleo, or SAD.

      A small percentage of people with terminal cancer get well when they stop eating. This has been noted in countless hospice programs. Many get well enough to get discharged from hospice, whereupon they resume their eating habits and die quickly.

      Ketosis has an anti-cancer effect. One can induce ketosis on a SAD, vegetarian, vegan and paleo diet. And one can overeat sufficiently on any of these diets to prevent ketosis. It is very, very hard to consume enough raw-vegan food to block ketosis perpetually. The energetic cost of digestion is so high and the calorie content so low. But it is possible. So it is not just about the diet type, but rather how it is implemented. So your evidence that Ornish reverses diabetes is not sufficient to establish that paleo does NOT reverse diabetes. In fact, it does.

    • paleogal

      The China Study has already been determined to be flawed.

      I don’t know anyone on Paleo who eats “rancid” animals.

      Grains are fed to animals to fatten them up – they do the same to people. All my “grain fed” friends have excess weight and many are vegans.

  • John

    “Grains contain omega-6 fats, lectins, phytates, damaging fiber, and gluten.”

    Really? All grains contain gluten? Clearly a well researched article you morons.

  • kappy

    I heard an MD, Ph.D oncologist who works for Kaiser Permanente give a talk last night. Guess what? He’s vegan, and it turns out that more and more doctors, especially oncologists, cardiologists and internists are switching to a vegan diet. He said there are two reasons for this: 1) the successes of patients who did not do what their doctors recommended, but cured themselves nutritionally, through a healthy, plant-based, unprocessed vegan diet; and 2) the snow-balling effect of a mushrooming number of studies that show time and again that people reverse heart disease, type 2 diabetes, rheumatoid arthritis, auto-immune diseases and cancers through a whole, healthy vegan diet. This Kaiser doctor now treats his patients nutritionally, supplementing with other treatments (often meditation, acupuncture, massage, etc.) and using chemo, etc. only when he believes it would help.

    This is great news because there is another aspect to making food choices that goes beyond considerations of what we might believe about our own personal health choices. In my youth I was an environmental activist, working to save native rain forests on the Big Island of Hawaii, where I made my home. Two of my children became vegetarians as soon as they understood that eating meat meant eating dead animals. I resisted this, as I believed back then that animal protein and the calcium in dairy were important components of a healthy diet, but my children stood up to me, as children often do, and over the years I learned to support them by learning to cook vegetarian at home. As for myself, I continued to eat meat, chicken, fish, and any and all dairy products, except milk. It took me a long time to come to the realization that I can no longer consider myself to be an environmentalist if I eat animal products. The more I have learned about the devastating, long-term effects of eating animal protein on climate change and its impact on the future lives of my own and everyone else’s grandchildren, I have come to the conclusion that, since having found a way to be a profoundly healthy vegan who eats a wholesome, plant-based diet (I especially recommend The Starch Solution by John McDougall, MD) I have no excuse for eating animal products anymore. Knowing what I now know, eating animals would feel self-indulgent and reckless. Even if I could only eat eggs from my own free-range, organically fed chickens and eat cows raised under the best of conditions in local pastures, how realistic is it that this option is available to very many people on this overcrowded planet? I’m not part of the solution if I participate in the behavior that must be changed.

    Keep in mind that elephants, camels, hippos—even rhinos—grow to be enormous and healthy while eating a diet of grasses, leaves and seeds! They have no problem getting enough protein or calcium to thrive and grow strong bones. Our human teeth resemble those of herbivores far more than the sharp, meat-ripping teeth of carnivores, and without refrigeration available in Paleolithic times, one has to question the accuracy of the paleo emphasis on the hunter aspect of the ancient hunter-gatherer diet. I would suggest it might have been the other way around, with seeds, berries, leaves, nuts and tubers as the basis of a daily diet in many localities, that may or may not have been augmented with an occasional kill. For those people who really want to eat like cavemen and women, killing the animal yourself, carving it up and eating it raw might be the way to go. For anyone wanting to be vibrantly healthy, while also supporting a healthier planet, watching the movie “Forks Over Knives” is an eye-opening experience.

    • Renny

      Kappy, I couldn’t agree more, especially all the views on the environment. I think the negative views on a “vegan” diet are related to people eating a poor diet but simply without animal products. A bad vegan diet is still a bad diet. To me, a proper healthy vegan diet means eating lots of whole food vegetables, lots of green leafies, beans, mushrooms, roots (onions, garlic), berries, nuts, seeds, fruits, and good sources of fat like avocado and flax seed. Small amounts of pulses, grains (NOT wheat), rice, and reasonable amounts of good starches (sweet potatoes, root veg, etc.) are good. Also, supplementing with Vitamin D and ensuring you get enough Vitamin B-12. Bagels, bread, pasta, granola bars, or any other type of highly processed, non whole-food “food-like” products are not really food, but are simply ways of delivering high-GI foods with no nutritive value. Forks Over Knives, and Eat to Live by Dr. Joel Furhman and John McDougall are on the right track. Also, I too highly recommend McDougall’s video on Steve Jobs. Given the size of the tumour, it was extremely likely that his cancer started very early in life due to his exposure to soldering all those early circuit boards and was not related to diet.

    • Rafa? B

      So far I know elephants and long living parrots also suffer aetherosclerosis, even they do not eat animal food at all. Isn’t it strange? I know many doctors and dietitians who recommend something they don’t follow. Some of them are fat vegetarians and all-eaters, who order to eat veggie. Many MDs (including) oncologists smoke, eat processed foods and just don’t care. My friend’s father, who has lung cancer due to smokig, was even bigger smoker than him. How could he help him? (My fiend’s father died).

      Thus, please don’t prove us that “more and more doctors, especially oncologists, cardiologists and internists are switching to a vegan diet”. Let they be healty. But remember: low carb-high fat diet, as well as vegan are beneficial, since provide low and/or natural (not processed carbs). And this is the common denominator. Other approach may be high carb diet (again: with natural carbs), but with almost no fat and with relatively high addition of good proteins (as Okinawian).

    low or no glucose in your diet is very unhealthy. This new trend of no glucose, doesn’t people the proper nutrition to properly metabolise food. You don’t get B-vitamins. What people are allergic to is pseudo glucose that comes from enriching food: fake glucose. Breads use to be a variation of sour dough, now they are enriched white bread. As it is well established, white breads, lack all kinds of nutrition.

    Most vegans have a grain based diet? Are these the same vegans who consume Bisquick, Pilsbury Crescents, Fritos, Oreos, Doritos?

    How does this relate to me, a healthy vegan who’s grains account for less than 5% of his diet?

    I have the same muscle mass and weight that I did a year ago when I started cold turkey and I’m still loading 100 bags of concrete a day at Ho Depot with no problem whatsoever.

    If I’m not mistaken….IGF-1 is found abundantly in all meat and dairy, regardless of if it’s grassfed/organically raised livestock or factory farmed. It is designed to grow little tiny babies into large beasts. Yes, it has a huge affect on cancer and tumor growth, I have one myself. The fact that you mention it as high in a high-carb diet means you may be selectively choosing your research and proof to further your own opinion, without doing all of the research on both sides. Please correct me if I’m wrong.

    I am a cancer researcher and I want to point out two misleading points in the article:

    1) Cancer cells can metabolise ketones. Ketone bodies have even been shown to promote cancer progression (Ref: http://www.ncbi.nlm.nih.gov/pubmed/23082721).

    2) IGF-1 is correctly stated as a contributor to cancer, but it is not said that the most important source of IGF-1 is dietary protein, especially animal protein (Ref: http://www.ncbi.nlm.nih.gov/pubmed/17571965).

    Your article lost its credibility when the topic of Cancer being a MODERN disease came up. Of course it isn’t! What makes sense is what scientists studying disease in ancient civilizations concluded recently, that “Cancer frequency in present populations is much more related to HIGHER LIFE EXPECTANCY than primary environmental or genetic factors.”

  • Bell Wilder

    I think what bums me out the most in these types of diet discussions is lack of focus on the detrimental effects these high animal protein diets have on the slaughter of animals, the environmental damage of slaughter houses, the over consumption of meat for “human” health and no regard for the well being of all earthlings. You may feel better, look better and have proof of such transformations. I know how amazing it must feel and you want to share it with the world. I get that. The problem is, there won’t be much of a world left if we don’t stop this push for a “caveman” existence. There must be a happy medium that slows down the killing and consumption of animals and still helps you maintain your “healthy ketosis”. Yes, I’m an animal rights activist but have no delusions that the world will ever stop eating meat so I focus more on the cutting down consumption as well as the elimination of slaughter houses. I think with our knowledge and extensive research it is possible to meet those needs but not with diets that push the major consumption of animals. It’s just such a selfish act. We are ALL worth saving.

  • Cheedoo

    How do you counter the most recent study from USC then? That shows protein spikes IGF-1 and by definition IGF-`1 feeds cancer… a high protein diet like Paleo is absolutely going to cause a spike in a person’s IGF-1 levels. I’m not a vegan, and in general I have tried to follow Paleo, but recent research INCLUDING this USC study is worrying — as is the at this point irrefutable proof that IGF-1 does cause cancer to grow at more speed.

  • Pingback: Fat, Everything You Need to Know()

    The studio proves NOTHING about eating a high-animal protein diet and preventing cancer. It talks about sugars and quick starches contributing to tumor growth, but that is not news. The connection between sugars and cancer growth has been made long ago…
    You can eat a diet low in sugars and white starch and be vegetarian or vegan. You can be gluten-free and be vegetarian or vegan. You can also eat plenty of saturated fat and be vegetarian or vegan…the healthiest tribes have been shown to consume a large amount of coconut.
    The study does NOT show that high animal consumption lowers cancer growth. There’s thousands of studies that show the opposite…there have yet to be any long-term studies on this. And the author is obviously biased, and incorrect in his anthropology listings, his says “Thus, the switch from the

    ” the switch from the ‘caveman’s diet’ consisting of fat, meat and only occasionally roots, berries and other sources of carbohydrate…”

    This is absolutely untrue. The amount of hunting that a tribe would have to do is impossible, especially considering the high energy expenditure of hunting. Almost every tribe in the world has a starch as the main staple of their diet…yams, tubers, cassava root, potatoes, palm starch, etc. Gathering plant foods and fruit is a more dependable food source that takes much less energy than hunting.

    So, I still have yet to see a single study done on the long-term affect of animal protein consumption, except to show it has an increased risk of cancers, heart disease, and even appendicitis.

    Vegan diet.? Even gorillas will stop eating veges when their body tells them it’s animal fat and protein time. they don’t resume eating veges till a large rat is eaten. Chimps do the same, but will tear to bits and eat another chimp from another family group.
    According to H R Clark, PhD, ND, when a person is on a low saturated fat diet, the double cell membrane, of your trillions of cells, which is comprised 40% of saturated fat, is compromised, Then, the necessary players that start and fuel all malignancies can gain easy entrance to cells. These players are nickel from poor stainless steel, that chelates the cancer nucleus and cancer complex into the cell, plus the other necessary players, such as specific parasites, bacteria, viruses, moulds, dyes, heavty metals etc.

    At Dr Clark’s clinic, any cancer patient who had been on a low sat-fat diet was stuffed with cream, egg yolfks etc to restore integrity to the cell walls.

    Dr Clark carried out over 1/2 million reproduceable, so scientifically VALID bio-resomance tests to identify these causes and pathways of ALL cancers.

    Great article with a lot a good research. Thank you for making it available. However, it does fall prey to the same anti-grain philosophy of paleo diet proponents, that is both out-dated and incorrect. The statement that people should avoid grains because they contribute to cancer is contradicted by real-world observations of people who consumed grains as a staple and lived healthy lives, free of chronic disease, and (most importantly) could have healthy, well-formed children. This includes the Anishinaabe (Great Lakes region, two species of wild rice), some isolated Scottish people (Outer Herbrides, oats), and others. Every argument made against grains in general (in your writing) is only true of some grains or true of unprocessed grains (i.e., wild and some heirloom kinds that are properly processed are nutritious foods). the anti-grain message is simply over-simplified. The statement should read something like this (so as not to contradict what we know about indigenous and traditional cultures): eat less grain (i.e., diversify your diet), choose wild and heirloom types, and select gluten-free kinds. I think you would benefit from reading this blog post: http://www.arthurhaines.com/blog/2014/6/5/dear-mark-sisson-where-paleo-recommendations-stand-in-contradiction-to-real-world-observations.

    This is so confusing… Dave, can you please address the grass fed meat consumption levels that you would set if you had stage 3+ cancer. I have read everything and this one issue is still hard to decide upon. Most research says that the mycotoxins produced by the cancer create the high ph environment that allows it to grow. I understand that grassfed meat is theoretically low in mycotoxins, but these are different from the mycotoxins produced by the cancer. The popular info says avoid all animal protein because it is too acidic and therefore conducive to cancer growth. So – if a regular bulletproof diet is high grassfed animal protein, what would the variation for a cancer patient be?

    and he narrated how his kidney was taken for exchange for

    money by Dr.Mckane and i gave it a trial with a doubtful mind

    because i never believed it. Lo and behold i was surprised

    when i met all the requirements spelt out, i was given half

    of the agreed price before the transplantation took place in

    my country home, in Ottawa Canada. And after the operation i

    still live like i used to live when i was having two beans

    kidneys, it has no harm and never hurt for a minute, are you

    I thought this was interesting. This video points out the issue with sugar, whether processed foods, or high glycemic vegetables. She doesn’t really reveal what type of diet she recommends as she’s trying to sell a book, but her website articles are very strong for a grass fed, organic, gluten free paleo lifestyle. I like the way she clearly explains the insulin and glucose connection. It makes so much sense to me.

    If high carb and grains are so bad and cause inflammation/cancer then why does Japan, China have such low cancer rates? They have low rates of all diseases/conditions. And they eat WHITE rise, not even
    brown, and vegetables. The carbs don’t seem to effect them. Mmm…makes ya wonder…

    Ironically, a study just came out that says folks who live on Mediterranean-style LPHC diets live just as long as those on CR diets.

    What I have never seen any study illustrate is that those on Paleo diets live longer. Then again it’s common sense really, as most “cavemen” did not live over the age of 30.

    My husband was diagnosed with grade 4 glioblastoma last July. Has undergone surgery, radiation and chemotherapy, and currently in 6th month of chemo 5 days of each month. Since radiation therapy was completed about 6 months ago the glioblastoma cancer have not gone. I was making research online on any possible solution that could help my husband and i came across CHARLOTTE’S WEB CANNABIS on how cannabis oil have helped alot of people in Colorado and outside USA to cure any kind of cancer. I was so happy and relief when i saw this website and i knew there was hope for my husband to live. I contacted the CHARLOTTE’S WEB CANNABIS via email charlottewebcannabisoil@gmail.com to get the high quality THC cannabis oil for treatment and prescription guidelines on how to use the cannabis oil for treatment of glioblastoma. As i am posting this comment today, my husband grade 4 glioblastoma is completely gone and he is healthy and living fine.

    Low carb diet is horrible for endurance athletes? Not according to Peter Attia.

  • Duke Mansell

    “They’re horrible for endurance athletes” where did this come from? cereal killers, art and science of low carb performance, etc. thats a random statement not backed by the current research.

  • disqus_ax7qut9jL1

    No good for endurance athletes??! I totally & utterly disagree, it’s not good for explosive athletes like sprinters but the more endurance your sport requires the better you’ll be on a LCHF diet (after you’ve adpated)

    Checkout http://www.fatchancerow.org for proof! Sami also has his own blog here http://www.samiinkinen.com, he details here when he went through a year of testing whilst adhering to a low carb high fat diet and his performances go from strength to strength!

    Without question my endurance has improved having followed a strict LCHF diet for about a year. On my old diet I struggled to get out of bed let alone get out on my bike!!

    Coming from a cancer researcher, an evidence for and against can be found for anything that one looks for. However, the truth is that cancer is a disease at a genetic and epigenetic level, theres a lot of foods that can help you live healthy, unfortunately not the ones the large corporations produce.

    I dispute the premise that “early” or “original” humans survived primarily on meat and that cancer did not exist. There were no cavemen, per se. Humans did not evolve – we are devolving. The original perfect diet was vegan (fruits and nuts), with herbs (vegetables) added later. People lived hundreds of years. Meat was added much later (about 1500 years later) and the human lifespan plummeted to 120 within 2-3 generations and continued to fall until modern medicine and sanitation increased it back to about 80-90. Historically, high meat consumption is contrary to long life. The results quoted here are anecdotal, recent, and not yet conclusive. High protein consumption is extremely hard on the kidneys, liver and other organs involved in digestion. Humans can obtain all of the necessary protein (40-60 grams per day) by eating vegetables and legumes. Body builders who have been consuming high levels of protein do not have long lives historically and are unhealthy overall except for having muscular bodies. Protein consumption does not produce endurance in an animal or a human. A lion that eats only protein can run only a couple of minutes and then he is finished for the day (hopefully he captured his dinner in the process). An elephant that eats only grasses and grains can run 25 miles per hour for hours!

    My mother has been diagnosed with brain cancer today. I will be finding out more details this week but am trying to be proactive in educating myself on treatment options. I know they have already put her on a steroid and a anti seizure med and I would like to ensure I do everything I can to inform her of natural remedies that may serve as alternatives or boosts for the probable long list of mess Ashe will be on. I read through hundreds of posts and comments today and as I’m a big supporter a Dave I stumbled upon yours which seemed to spark a large amount of interest for me. I’m interested in getting in contact with you for an update on your situation and any help you may be able to provide.

    Anything is appreciated.

    King regards,

    I really appreciate this discussion. My opinion is that “let food be thy medicine” – so whatever medicine you are in need of should be your food. I think the thing with the paleo diet that is often overlooked is that those early people had totally different microbiomes, were hosting parasites, ate their meat raw and bloody, and had shorter lifespans.

    On the other hand, I think the China study illuminates a lot of interesting data in the animal protein sphere – think aflatoxin and mouse model casein studies (although yes this is dairy protein).

    I would agree that you must follow your body, how you feel, what you need to heal and define your diet. We are way past paleo times – and way past Gerson times. Gerson originally had raw liver calf shakes as part of the protocol. So there’s something to the animal protein argument.

    With all the toxins, depleted microbiomes, and lack of parasites & infections in our overly toxic and developed world – you most likely have to take something from both sides to come up with what works for you.

    I was diagnosed B-cell lymphomas which are types of lymphoma affecting B cells. Lymphomas are blood cancers” in the lymph nodes. They develop more frequently in older adults and in compromised individuals.I remember being on my knees praying, “God, I will fight as hard as I can if you just let me get through this chemo stuff.” When I went in, Dr. Noy said, “I have something that’s going to help. I’m going to give you Procrit after you get your chemo.” Once I got the Procrit, I never felt again like I had after that first chemo treatment. I got tired and I didn’t feel 100 percent, but I was really okay. My cancer became very real to me once I lost my hair. But by then the mystery, the uncertainty, was sort of gone. Not gone, but it just wasn’t at the forefront. There were things that I started looking forward to doing, like going out and not just staying in the house. By then, the weather had started getting really nice, and I decided I needed to get out. I would go for a long walk or take the subway into the city and look in the store windows. It’s funny, people I didn’t know would chat with me on the bus, on the train. We would talk about anything. That made me feel a lot better. It come a day when i was told by a lady to try and do some research on the internet for help maybe there will be a cure to my Cancer.I google for treatment for cancer and i saw some testimony about the herbalist called Dr ODIA and the great work of his Herbal Herbs. With the hope i have in God i believe this to be the end of my problem for i have pray for a solution from God. I contact Dr ODIA with the giving email and also click on his website to see his work. I finally believed in him and told him about my problem. He prepare His Herbal medicine and which I was advice to take for three weeks, There are lot to say about Dr Odia, I Thanks God that this man was used to end my sorrow All my pains and sorrows turn to joy and history from the day i came in contact with Dr ODIA, Who really help with his herbal herbs, I WAS TOLD HE IS A HERBALIST AND HE CAN BE OF HELP, I gave him a try and it really work out for me, today here I’m cured of B-cell lymphomas. Contact him via: (drodiaherbalistcenter@gmail.com ) +2349076581184.

    Where are THE STUDIES ? We don’t want opinions, we want FACTS. I don’t think you know what you’re talking about friend (Even tho i’m a low carb vegan, i’m not against switching to keto, if provided with E.V.I.D.E.N.C.E.)
