Coffee Benefits: Perform Better & Live Longer

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

Coffee will kill you.

At least that’s what some caffeine-deprived people have come to believe. Coffee gets a bad reputation for causing jitters, stomach discomfort, even cancer. You’ll also hear that “acidic” coffee causes osteoporosis. Before explaining how we came around to believing those things, let’s look at some of the proven benefits of coffee. I’m writing this from the perspective of someone who had all of those symptoms when I drank coffee, which led me to give up drinking it for five long, dark years. But being a biohacker, I dug into the research and discovered that not all coffee is the same. I drink 1-2 cups of Bulletproof Coffee every day and experience the health benefits of coffee without the problems coffee allegedly causes.

That said, there are some valid concerns with coffee.

Many of the studies that “prove” coffee is bad for you are based on epidemiological data, but there is also epidemiological data in favor of coffee consumption, as well as lots of clinical research. It is my belief that most studies showing coffee is unhealthy do not control for the production process behind the coffee. People don’t realize it, but different processing methods introduce radically different amounts of potent toxins into the coffee depending on how much and how long the coffee is allowed to ferment and on how damaged the beans were before roasting. That’s why I explain how to find good coffee in your city. It’s that simple: good coffee = good performance. Bad coffee = bad health.

Observational data doesn’t prove coffee is good for you, but its a nice place to start. We will cover some clinical trials at the end of this article that do prove coffee is good for you.

Coffee Benefits

Long term coffee consumption is associated with a lower risk of type-2 diabetes. The more coffee you drink, the lower the risk.

Coffee consumption is associated with increased insulin sensitivity and improved beta cell function.

People who drink six or more cups of coffee per day are 50 percent less likely to develop diabetes.

In a study on 47,911 Americans, there was a correlation between coffee drinking and a lower risk of prostate cancer. Men who consumed the most coffee (six or more cups daily) had a 20% lower risk of developing any form of prostate cancer.

Coffee drinking was even more beneficial for severe prostate cancer. Men who drank the most coffee had a 60% lower risk of dying from prostate cancer. Drinking one to three cups of coffee per day was associated with a 30% lower risk of lethal prostate cancer.

Women who drink coffee are less likely to suffer memory loss later in life.

A Scandinavian study found people who drink boiled coffee (similar to Turkish or French Press) are less likely to get cancer.

Women who drink coffee are less likely to develop depression.

Women who drink coffee are less likely to get a stroke.

Women who drink coffee are less likely to develop breast cancer.  The difference is small when adjusted for other factors, but statistically significant.

In one of the largest reviews to date, coffee drinkers had a slightly less chance of overall death.

There’s a fair amount of observational data in support of drinking coffee. Who cares? We don’t want to fall into the same trap as high-carb, low fat extremists like Ancel Keys and T. Colin Campbell who torture data until it tells the story they choose. Correlation does not prove causation, but it does create some questions. Like this one:

What can coffee do for you?

Here are five of the reasons I drink coffee for my health and performance, and why you should consider it too;

1. Better Memory Recall

When Bulletproof practitioner Andrew took the LSAT, his preferred source of brain fuel was a cup of Bulletproof Coffee. The healthy fats, nutrients, a small amount of added dextrose (and a little caffeine-amplifying Aniracetam) along with a few other techniques allowed him to do far better than he would have otherwise.

Besides giving him a burst of energy, caffeine improved his ability to remember the answers.  A study in 2005 showed caffeine could improve short term memory recall. The study didn’t use coffee per se, but caffeine tablets, which isolates only one of the complex chemicals in coffee. As long as you aren’t drinking decaf (I’m going to cover that topic as well), coffee ought to improve your mental skills before a test or job interview as long as you don’t have so much you get overstimulated.

I’ve written about the cognitive benefits of coffee before. In one study, coffee was able to produce the same mental state as Chi Gong exercises. That’s way cool!

Be careful however, one study showed that chronic high dose caffeine caused decrease blood flow to the brain. That’s why I drink one cup of coffee per day on average, or two on very long days. Smaller doses of coffee on a daily basis are beneficial. Large doses all the time are detrimental.

2. High Antioxidant Content

For Americans, coffee is the number one source of antioxidants. This won’t be true if you’re eating The Bulletproof Diet, but it’s important to remember when you think of the average American. If you’re eating a Standard American Diet, coffee might be one of your top health foods.

Coffee contains numerous antioxidants, but something many people don’t know is that caffeine is an antioxidant. The caffeine in cocoa, tea, and coffee is a powerful antioxidant that can even protect against Alzheimer’s.

Roasted coffee beans have a higher antioxidant content, which is why we use a special roasting process for Bulletproof Upgraded Coffee Beans.

3. Enhanced Insulin Sensitivity (sort of)

Some studies indicate caffeine can cause insulin resistance. However, the research is conflicting.  An eight week study in September of 2011 showed no difference between caffeinated coffee, decaf coffee, and water on insulin resistance, insulin secretion, or glucose tolerance. In another study, coffee consumption improved glycemia markers including insulin sensitivity and glucose tolerance.

I’m going to cover this topic in more detail soon, but there’s no reason to stop drinking coffee over fears of insulin resistance. Reasonable amounts of caffeine can improve insulin sensitivity and other markers of glucose tolerance. In general, people who drink moderate amounts of caffeine have better insulin sensitivity.

Coffee is also a rich source of polyphenols which improve carbohydrate metabolism.

4. Rapid Fat Loss

Coffee is a potent thermogenic. It increases metabolic rate and stimulates movement. It also increases fat mobilization and oxidation which promotes fat loss. If you pair this with our XCT oil (another thermogenic) and the nutrients from grass-fed butter in Bulletproof Coffee, it’s no wonder one of my clients was able to lose 75 pounds in 75 days.

5. Improved Performance

Caffeine is an ergogenic aid, meaning it increases power output.  This is true for both aerobic and anaerobic exercise.  If taken before a workout, caffeine could improve your performance and give you an edge over your opponents.

There is some evidence high doses of caffeine can reduce blood flow to the heart during exercise.  The mechanisms aren’t fully understood, and it was in extremely large doses.

People respond to caffeine in different ways, so be sure to test its effect on yourself.  If you consume reasonable amounts, it will likely improve your performance.  The bottom line is, as always, did you go faster or not?


Coffee has received an undeserved reputation as being unhealthy, when in reality it improves brain function, scavenges free radicals, and decreases your risk of disease.  It’s a rich source of polyphenols and antioxidants.  The caffeine in coffee can increase memory and improve glucose tolerance, fat loss, and exercise performance.

High amounts of caffeine can cause problems such as decreased insulin sensitivity, impaired brian function, jitters, nervousness, stomach discomfort, and decreased exercise performance.  As with any drug, you can overdose.  Moderate amounts of coffee will do nothing but good for most people:

  1. Coffee can improve memory and brain function.
  2. Coffee is an excellent source of antioxidants.
  3. Coffee can improve insulin sensitivity.
  4. Coffee can accelerate fat loss.
  5. Coffee can improve exercise performance.

My Recommendations

  1. Regular coffee consumption is beneficial as long as the coffee is mycotoxin-free.
  2. If you need coffee to function – you’re addicted and need to find a better solution.
  3. One cup a day is perfect.
  4. Two cups a day is okay.
  5. Three cups a day is the maximum.
  6. Use this guide to make sure your coffee isn’t toxic.  Or watch this video.
  7. If you want to get the most out of your coffee, read this and make Bulletproof Coffee.

IMPORTANT: Be even more careful with your decaf coffee sources. For decaf, most coffee processors use the lowest quality beans with the most toxins for decaf. Even the Swiss water process doesn’t use higher quality beans. Once an already damaged bean is stripped of it’s caffeine, until it is roasted, it is at an even higher risk of mold infection as caffeine has a protective effect against mycotoxins. Besides its lower antioxidant value, unless it is carefully processed, decaf is practically guaranteed to contain mold toxins or other bad stuff. Learn more about safe decaf in this article.
If you consume reasonable amounts of coffee on a regular basis, you can get all of the benefits with none of the side effects.

Update: The Washington Post just ran another article highlighting the benefits of coffee. It’s worth a read.

By Dave Asprey

  • Trying to calculate the daily coffee intake. When you’re talking about 1-3 cups above, how much exactly is a “cup” of coffee? What about espresso?

    • Little Cub Lou

      That’s an excellent question, Chris, and there’s no way to answer it that will leave us any less confused. According to a response given to your question on Wiki—-“There is no legal “standard” coffee cup; although the most correct answer could be either 5 fluid ounces [for brewed coffee] or 6 fluid ounces [of cold water]. Most table settings come with cups that hold approximately 6-9 fluid oz.

      The SCAA defines the gold standard for a cup of coffee as 6oz of cold water resulting in about 5-1/3 fluid oz of brewed coffee (some water loss due to evaporation and absorption by coffee grounds). Most manufacturers in the United States round this off to 5 oz for marketing purposes so that a 50 oz pot is sold as a 10 cup carafe. If a coffee maker is marked with measurements in cups on the side it usually indicate 5 fluid ounces for each cup.

      Coffee makers and distributors in the United States refer to a “standard serving” of coffee as 6 fluid oz of cold water (the term “cup” is not used on the typical coffee can/package/box sold in a supermarket). This can result in a slight overfilling of coffee makers since a “serving” of coffee (as defined by coffee producers) is usually a fraction of an ounce larger then the typical “cup” (as defined by coffee brewer manufacturers).

      Specialty coffees such as expresso, french press makers, etc, sometimes use other sizes.”
      My China coffee cups hold 5-6 oz. of brewed coffee while my coffee mugs generally hold 8-16 oz. So I guess when I drink my morning coffee in my 16-oz “cafe-au-lait” mug, I’m actually getting my daily quota by some standards, although I often drink another 8 or 12 oz. later in the afternoon.
      Now that i have completely confused you, let’s just raise our mugs and enjoy a coffee together! LOL

  • Leonardo Cavaletti

    Any objections on taking a caffeine pill (rougly 1.5x the amount of caffeine in an espresso) instead of coffee?

  • I found your blog 4 days ago and I think I have read every post. I have been drinking your recipe with regular drip grind from the store. I’m using coconut oil for the MCTs in addition to grass fed butter. I also tried raw egg yolks for the first time. OMG, that is amazing too.
    I live 40 miles NW of Chicago. There are a handful of small coffee roasters in the city and some retail stores as well. I found a wholesale coffee roaster near me. I asked the roaster all the questions on your list. He said they have many single estate, high altitude, wet process varieties! He said that mold is not really a problem in general. The roaster gave me a couple shops close by which sell their beans. My husband bought a pound of Colombian Supremo and a conical burr grinder. I mentioned in a comment on another post that my organic dairy sells raw, grass fed butter for $14/lb. DH found Kerrygold for 5.88 per pound (2 pkgs. ) Since it is going into coffee, it isn’t as important to be raw, I guess.

    I had no idea it was going to be this easy. I’m really jazzed.

    • Marisa

      I live 35 miles NW of Chicago as well – where do you get your butter? Where did you get that coffee?

  • You can add cholinomimetics to the list of interesting sympathetic stimulant molecules contained in coffee.

    Also, this author strongly believes in getting increased insulin sensitivity from coffee IF consumed without sugar or protein as the first “meal” of the day. Bulletproof Coffee fits in quite well with this protocol.

    • Thanks Naomi! You always have the MOST interesting comments 😉

  • Another interesting post. I’ve been back and forth with this. The studies contradict each other. It’s really hard to tell what negative effects coffee has at this point. Somehow, I believe that it’s somehow related to certain kinds of cancer. I mean, there are still people getting cancer who have no idea how they got cancer. We are still largely clueless about this!!

  • Anon

    Any tips for avoiding getting your teeth stained from drinking coffee? Maybe use a straw?

  • Desiree

    Hi Dave – thanks for sharing your explorations in nutrition and health! So according to 23andMe, there’s a gene that indicates what kind of caffeine metabolizer you are. Understanding this differentiation can more than account for the argument over coffee benefits: One way and 2-4 cups of coffee/day is good for you, gives protective factors you mention. The other way and more than the caffeine in a cup of coffee/day (coupled with, say, increased chance of atrial fibrillation, like I have) could be asking for a heart attack. I’ve switched down to the equivalent of a cup/day in tea+chocolate, which is a slower ‘burn’ for my type, and don’t get jitters anymore. – D

    Hi Dave- I absolutely love your bulletproof coffee recipe and can always count on it to take my morning to the next level. However, I’d like to know your thoughts on green tea.

    I can already speculate that it has a high potential to be contaminated with mycotoxins and the like, yet there are a ton of health benefits to be obtained from it. Would you recommend green tea as a part of a bulletproof diet?

    • Mia C

      I realize this post is 4 years old but in answer to others who may read it I just got done reading his book and he has a recipe for Bulletproof green tea in there. If you get the Matcha from Japan, that stuff is top of the line. The company Gold Matcha makes phenomenal green tea with unbelievably great production practices. If it was good enough for Samurai and warlords before battle, I’m pretty sure it’s good enough for us. Toxins aren’t a big concern to me, but I do have to say I’d think twice about some Chinese teas, herbs, supplements and vitamins that have flooded the market lately. Some’s ok, some is not.

  • Craig

    being in health 20 years, I can say based on direct observation than ANY stimulant is going to tire out the endocrine system. This cannot be disputed. Anything overly stimulated gets tired over time.
    I do agree that types and preparations go a long ways. I was overjoyed by getting this link from a friend.
    Everyone is different. Some are born with more inherent energy, and these types can get away with coffee more easily. Do not get me wrong, I love coffee too, but it has a price.
    I think we all try to share what works for us, but lets all keep in mind that what is medicine to one, can be poison to another. There are FEW universal across the board recommends in diet and health. That will work for all. Except fresh foods, organic, and more vegetables.
    With this in mind, I feel it is more responsible to say, “This works for me, in my desire for a fast-paced lifestyle, but it may not be the best thing for you.”

  • Scott Jerzyk

    Anyone have any thoughts on the cross-reactivity of coffee and gluten antibodies? I’ve seen several blog posts on this lately.

    • Dave Asprey

      The data is very spotty. The Cyrex labs offer a test to see if it’s a problem, but the physician who spread this stuff at PaleoFX didn’t get facts straight. He said “10% of coffee cross reacts with gluten.” But a whole cup of brewed coffee has on average .28 grams of protein. Even if you eat beans directly, they are approximately 10% protein, and all protein in coffee does not cross-react. Coffee protein is mostly glutamic acid, glycine and aspartic acid. There are tiny amounts of threonine, isoleucine, leucine, lysine, cystine, phenylalanine, tyrosine, valine, arginine, histidine, alanine, proline and serine. It is the histidine that makes bad coffee develop biogenic amines. (BTW, coffee beans contain seven of the nine essential amino acids…but that’s kind of misleading since you don’t get significant protein in brewed coffee anyway.)
      We also don’t know what percentage of the population has the problem – is it high or low? We don’t have data, but I’d guess it’s low, because we don’t see GI problems or other problems of gluten in people who are GF/Bulletproof but drink *clean* coffee. (btw, what brew method, with what beans, were tested for cross-reactivity?).
      Come to think of it, I do get gluten-like symptoms when I drink bad coffee, but I believe that’s from the biogenic amines and mycotoxins, not from any sort of gluten-like cross reactivity. They happen faster than typical gluten symptoms for me. In addition, my hashimoto’s is GONE completely, and it comes back if I eat wheat. But I drink (only my) coffee daily.
      The same doctor who talked about this said, “There is nothing good in coffee but antioxidants” which is patently untrue if you look at its affect as an anti-inflammatory in the brain, its effects on cancer, and the many other things I blog about.
      My advice? If you’re worried, get the Cyrex coffee panel. (and let me know what you learn!). Or just biohack it. Try two weeks without, two weeks with, and see how you do. I think the answer will be obvious. ? Also, stick to paper filters if this is your concern and use a bigger grind. However, people with ADD tend to do better with a French Press/unfiltered coffee.

  • Hey Dave, great information love the blog. Just one question i was hoping you might be able to clear up. I read Branden Brazers book Thrive (Vegan i know ehehehe !) and he mentioned that coffee, being a very strong stimulant, places a great deal of strain on the adrenal glands. If this is true, how dose daily use effect the regeneration of the gland. Am I going to have to “repay” the biological dept of being stimulated by coffee at a later time? Or am I safe following the recommended consumption of 1-2 cups a day?

    • Dave Asprey

      That is a common misconception…just as grass fed meat is not the same as grain fed and has diff biological effects, moldy coffee has a different impact on the body than pure mold free coffee.

        I have been avoiding coffee because of Dr. Berg’s assertions that it (more specifically the caffeine in it) is bad for my (adrenal) body type. I would like to try the bulletproof coffee to see if that might be better, but I was wondering if you knew of any ways for me to tell, based on how I feel or any particular nutritional indicators, if this is a better option for me? Or do I just have to “wait and see” if my weight comes off more easily?

      • CK Thiruvathukal

        I absolutely don’t buy that there aren’t endocrine effects from coffee. I have a few living proof examples. It is a stimulant and almost everything can potentially affect the endocrine system, mold or not. Mold does make it worse. I’ll look at the coffee but wouldn’t use it for a health kick. This reminds me of the whole wine thing. Good writing though.

    Hi Dave,
    I have been trying the diet and love the bullet proof coffee. However I am not experiencing positive results posted by others. I am eating foods only from the green list, following the intermittent fasting and taking the recommended supplements. I lost one pound during the first week and have gained 2 pounds during my second week. What gives? All my male friends who are doing this lost a lot of weight immediately. One even stopped intermittent fasting because he was losing weight too quickly. All my female friends who started with me are experiencing the same thing. We feel bloated and tired and are constipated too. I am very familiar with detox reactions as I do a detox every 3-4 months and this is completely different. I have a scale that measures body fat as well, so I know that I am not losing body fat and gaining muscle. Is there some extra advice that you would give to women or is this way of eating just not right for me?

      BLOATING… Drink Apple Cider Vinegar before and during meals. I wish someone had told me. Too much fat; my body won’t digest it –> DISTENTION (or Jelly Belly and some gas/bloating); and beatine-hcl doesn’t help me.

      • newbie

        Thanks so much. How much would you recommend?

        • Sean

          A few tablespoons, in as little water as you can stand. Just experiment… Seems to me, drinking some stout ACV DURING the meal is most important… really get those enzymes mixing into the fatty meal.

          My theory is these endogenous enzymes just aren’t getting produced enough in some people (myself) and after a month or so on a high-fat diet, some fats clog-up-the-works, and the distention is somehow corollary of that enzyme-deficiency–>mechanical-inefficiency problem….

          There’s only so much the Migrating Motor Complex alone can do to help this….. Low fat diet + plenty of walking (vacation) will annihilate the distention in a week.

    While you’ve got a lot right, you’re in denial about coffee. Ever heard of Camellia sinensis? Green or white tea? The cognitive enhancing properties of that plant are >> than coffee.

    While mounting evidence points to adrenal exhaustion in coffee users, white and green tea pack many multiples of the ORAC with none of the risk (though tea grown in the wrong environment can build up fluoride, but if you’re drinking tap water you’re already screwed).

    You should research Bacopa monnieri if you haven’t already.

  • Hi Dave –

    Good and bad here, so I hope you read what I have to say.

    First, we’ve tried the Bulletproof Coffee concept (using standard coffee and coconut oil in place of MCT), along with your diet and the transformation has been nothing short of amazing.

    I’m clear, focused, in charge of my emotions, happy, positive and feeling like the old me I thought was long gone.

    To anyone considering this approach, TRY IT! It works and we’re only getting started.

    Now – the bad, which has nothing to do with the diet or the coffee . . .

    We ordered your coffee and MCT oil 9 days ago. We’re still waiting to receive it. And because there is no tracking information we have no idea when it will be here.

    UPS Sureshot is, by all accounts I’ve read, horrible service.

    Look, in the age of Amazon Prime you must realize that free shipping that arrives in 1-3 days has become the expectation for many of us.

    I paid you over $12.00 for shipping and you’re using UPS Sureshot?! That’s very NOT Bulletproof.

    You’d be better off, and so would your customers, going with USPS Priority. They supply the boxes and you could ship out what we ordered for under $8.

    I’m OK with paying $12.00 (not really but what choice do I have?) but to sit here waiting in this way – dude, it pisses me off! Scrap this second-rate service and take care of your customers.

    That said – sorry to rant because I thank God for putting you in the world and discovering/sharing what you have.

    All the best to you – John

      Shipping is THE WORST with the Bulletproof company. I’ve waited OVER 10 days before. Sometimes even over 12 days! And my deliveries have been delivered to wrong addresses and I had to wait even MORE days for UPS to get it right, then I was the one that had to drive to UPS to get it! I’m sorry but if you’re already paying a more than ridiculous amount for shipping and it takes that long, and UPS messed up or Bulletproof processes the label wrong (Bc it’s happened to me!) why should I have to pay when I ended up having to be the one to go and drive to a UPS and get it myself!! I love bulletproof, but my goodness, the shipping is a joke.

    If coffee is so great, why does it give me migraines? I tried Upgraded Coffee but couldn’t tell any difference so I just try to choose wisely from my local roaster (“Thanksgiving Coffee: Not Just a Cup, But a Just Cup.”) I do love the Bulletproof Coffee recipe made with decaf, though. I just can’t tolerate the caffeine in regular coffee. Thanks.

      The coconut oil and butter slows down the absorption of the caffeine so you might find you tolerate it better in BP coffee.

    How can anything make you less likely to die, don’t we all die eventually?

    coffee or tea..with 1-2 cup consumption..ofcourse with less sugar is good and will have some benefits and i’ve observed this in my elders

    How about what you are drinking out of? What you are making it in, plastic etc

    I have been Intermittent fasting for years, with consumption almost always between 30 min (1 meal) and 6 hours (2 meals). I love your buttered coffee in the AM, but does this not break the fast?

    Can you make the coffee in a stainless steel stovetop espresso maker?

    has anyone here discussed Green tea vs Coffee? I am a fan of both, in limited quantities, but my husband doesn’t like the taste of coffee AT ALL!

    • Mark

      Try it with Chai Tea or add a little bit of cocoa to the mix, a heaping half teaspoon makes it more like hot cocoa than coffee.

    what taste better bulletproof coffee or caveman coffee?

    • Rawstagirl

      bullet proof is way better, i did not like the caveman coffee at all! I was excited to have another choice but it seriously tasted like my coffee enema coffee which is a super high quality coffee but it is for enemas and so the taste is just not full and pleasing to the palate. Just my humble opinion.

  • Espresso that is decaffeinated utilizing the Swiss Water Process loses no cancer prevention agents and tastes extraordinary. Most great cafes utilize this sort of decaf.
