Why Getting Your Nutrition Only from Food is A Bad Idea

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


All your life you’ve eaten a “healthy” diet.  You’ve followed the USDA Food Pyramid from the beginning, and were always told supplements were unnecessary as long as you ate a balanced diet (whatever that means).

Maybe you’re wiser now, and are following a higher nutrient diet.  Either way, one of the most repeated beliefs among health conscious people is that you can – and should – get all of your nutrients from food.  With over fifty percent of the nation consuming a multivitamin, this isn’t a universal belief.  However, multivitamins often make people think they can eat even worse, which isn’t exactly productive (more on those later).

Many people are shamed into avoiding supplements with statements like “So you’re too lazy to eat real food?  You think you can fix everything with a pill?”  We all have those health conscious friends who decry supplementation as dogma.  They are confusing drugs like statins with nutrients.  They are not the same.

In any case, you’re not dead yet, so you must be getting the right nutrients.  Supplements are unnecessary… right?

 10 Reasons You Should Take Supplements

1. You Eat Crap a Standard American Diet

Grains, legumes, and most forms of modern dairy are not food.  The purpose of consuming food is to nourish the body and mind.  These foods do the opposite.

First of all, grains, legumes, and conventional dairy are nutrient deficient (or void).  They contain extremely small amounts of nutrients, most of which are malabsorbed.  Grains and legumes deplete nutrient stores and interfere with nutrient absorption.  They are toxins in themselves, which increases your nutrient needs.  Grains and legumes both cause intestinal damage which further decreases your ability to absorb nutrients.  Even if you’ve stopped eating these foods, you may be in nutrient debt or have lingering intestinal damage which is interfering with nutrient absorption.

Due to inflammation caused by other foods toxins, dairy protein is often inflammatory.  Conventional dairy also contains mycotoxins which are extremely damaging.

2. Soil Depletion

Improper farming practices deplete the soil of nutrients.  When plants are repeatedly grown on the same land, the soil loses nutrients faster than they can be replaced.  Over time, the plants have fewer nutrients to grow.  Fertilizer contains just enough nutrition for the plant to survive until harvesting, but not enough to support human health.  This results in plants that have 75% fewer micronutrients. (“Not On The Label“, p213.) In addition, most plants are not harvested fresh.  They sit on trucks, shelves, and counters for weeks before being eaten.  Over time, the nutrient content of these plants decreases.

Most modern fruits and vegetables are grown to increase their sugar content, not their nutrient value.  As a result, most of the common fruits and vegetables are artificially high in fructose and sugar and lower in key nutrients.

When plants contain fewer nutrients, the animals that eat these plants are also malnourished.  A study published in the Journal of Nutrition and Health found copper levels in the UK have dropped by 90% in dairy, 55% in meat, and 76% in vegetables.

3. Water Depletion

Water is also depleted of minerals due to modern production methods.  There is a huge variation in the mineral content of bottled and tap water, with tap water generally having more.  Water filters remove important minerals such as magnesium, which was a main source of magnesium for early humans.  If you don’t use a filter and you don’t have a well, it’s likely you’re consuming dangerous amounts of fluoride and/or are deficient in magnesium.  This could explain why people who drink water higher in calcium than magnesium develop more myocardial infarcts and ischemic heart disease.

4. Low Calorie Diets Are Low Nutrient Diets

I know this is a crazy idea, but starving yourself is bad.  Consuming a low calorie diet means you’re consuming fewer total micronutrients.  Humans are designed to consume a large amount of calories, and it doesn’t make you fat.  When you eat less (as everyone says you should), it’s easy to become malnourished.  When you’re consuming low quality foods, you have to eat even more to obtain the right amounts of nutrition.  This is one more example of why food quality matters.

What do we mean by low calorie?  According to this study most diets require 27,575 calories to supply all the essential micronutrients.  If you’re eating less than that, and are following something like the USDA diet or the South Beach Diet, you’re deficient in nutrients.

Animal foods are generally higher in calories and nutrients, so it’s no surprise that’s where the majority of calories came from in early human development.  Since the modern trend is to reduce the consumption of animal foods, people are consuming fewer nutrients.

Pesticide-treated vegetables are lower in phenolics than organic ones.  This is because polyphenols are produced as a defense against bugs and pathogens.  When there is no reason to defend themselves, the plant stops producing polyphenols.

There is pesticides. This is despite sometimes being contaminated anyway.  It should be mentioned that many studies show organic foods are not higher in nutrients.  However, that’s going by the USDA definition of organic – not “organic” that you would find in your back yard.  Fresh fruits and vegetables grown at home in well fertilized soil are going to be higher in nutrients than USDA organic versions.

Plants treated with pesticides are also lower in phenolics than organic ones.  This is because polyphenols are produced as a defense against bugs and pathogens.  When there is no reason to defend themselves, the plant stops producing polyphenols.

There is also evidence that glyphosate – RoundUp herbicide – chelates minerals in crops on which it is sprayed. It remains to be seen how much of an impact this effect has, but it’s safe to avoid GMO foods for a variety of other reasons.

Unfortunately, organic is not always possible due to financial or logistical reasons.  Even when you can find organic foods, they aren’t necessarily better.

6. Grain-fed Meat & Cooked/Conventional Dairy

Compared to grass-fed meat, grain-fed meat is abysmally low in antioxidants, micronutrients, fatty acids, minerals, and vitamins.  Grains are not a food for humans or herbivorous animals.  When herbivores are fed grains, they become malnourished, just like humans.  Grain-fed meat and farmed seafood can also serve as a carrier for more toxins, which increases nutrient needs.

Raw, unpasteurized, unprocessed, full-fat dairy can be good for you, but the kind most people buy at the grocery store is not healthy.  The majority of nutrients in milk are found in the fat (cream).  When you remove or reduce the fat, you are removing and reducing the nutrient content.  Pasteurization destroys some of the nutrients in both skim and full fat milk.  Conventional dairy is also high in aflatoxin and other mycotoxins that were in the cattle’s feed.

If you eat grain-fed meat or conventional dairy – supplementation is a good idea.

7. Toxin Exposure

Your body needs nutrients to deal with toxins.  When more toxins are present, you need more nutrients.  If you’re living in a cave or the garden of Eden, this will be less of a concern.  If you’re like the rest of us mortals – you’re exposed to a litany of toxins on a daily basis.

Here are just some of the things your body has to contend with:

    1. Xenoestrogens (plastics, BPA, some molds, petroleum products).
    2. Industrial solvents and cleaners.

Our bodies weren’t designed to deal with these toxins using only nutrition from food. They just weren’t. So if you plan to get your nutrition only from food, you should plan to get your toxins only from the Garden of Eden. Good luck with that.

  • Unnatural lighting.
  • Food toxins (not a problem if you’re eating Bulletproof).
  • Stress and lack of sleep.

There are hundreds of other sources of unnatural stress that increase the body’s need for proper nutrition.  Even if you’re doing everything right in terms of diet – it’s almost impossible to get all of your nutrients from food.

Our bodies weren’t designed to deal with these toxins using only nutrition from food. They just weren’t. So if you plan to get your nutrition only from food, you should plan to get your toxins only from the Garden of Eden. Good luck with that.

8. Nutrient Absorption Declines With Age

Several studies have shown kids need more nutrients to support growth, and older people need more nutrients due to malabsorption.  As people age, they often begin taking medications which can interfere with nutrient absorption.  This means you need to take more nutrients in the most absorbable form possible.

9. Exercise Increases Nutrient Needs

Athletes often think tons of exercise is the key to a long and healthy life (it’s not).  They are among the first to denounce supplementation as unnecessary, often with the idea that exercise is the best medicine.  I don’t advocate high amounts of exercise, but this is an important point.  If you’re doing enough exercise to substantially deplete energy reserves, you’re also using more nutrients for energy production and recovery.  As a result, athletes are at an even higher risk of nutrient deficiencies.  Since many athletes eat a low nutrient, high toxin diet – this is a serious concern.

10. Supplementation May Help You Live Longer

Aging is a natural process, but it’s not fun.  If there are supplements than can delay this process, why not take them?  As long as there isn’t an undue risk of harm, it’s hard to justify avoiding a substance simply because our ancestors didn’t have access to it.  There is good reason to believe a higher intake of nutrients may prolong life.  Our hunter-gatherer ancestors may have been malnourished at certain times which is not beneficial.  If supplements can buy you a few more years of quality life, why not take them?

11. Expense & Health

Whether we like it or not, sometimes supplements are cheaper than real food.  In the case of something like salmon, it may be better for you to supplement with a high quality fish or krill oil than to settle for a farmed variety.  Farmed salmon is low in omega-3s and high in toxins.

Farmed salmon are higher in parasites and bacteria.  In order to hide the sickly appearance of farmed salmon meat, the fish are fed a pink pigment to change their tissue color.  Farmed salmon contains 16 times more PCB’s and pesticides than wild.  Wild salmon is often more expensive than grass-fed beef, and presents more of a health risk than benefit.  Grass-fed beef has enough omega-3’s by itself, but supplementation may be a good idea for some people (like kids).

We live in a stressful, toxic world, and it’s a normal, healthy, optimized human behavior to understand the toxins and counteract them whenever possible. Hiding your head in Paleo-sand won’t make the effects of these toxins go away. Neither will eating some vegetables.

The idea that you can get all your nutrients from food is fine in theory, but virtually impossible in practice.  Soil and water depletion, food and environmental toxins, poor absorption, pesticides, exercise, and lack of calories can all cause nutrient deficiencies.  There is evidence that consuming nutrients from food is more beneficial than supplements, which is why you should focus on a nutrient rich diet first.  However, it’s rarely enough.

If you want to be Bulletproof, supplementation is a great start. Handicapping yourself by “only getting nutrients from food” is not a good idea, even on the Bulletproof Diet.

Do you think supplementation is necessary for optimal health?

    Interesting article. I’ve done some experimentation with diet myself in order to see how hard it is to get sufficient nutrition through food alone. I built a program that would take recipes and analyze them according to values from the USDA food nutrient database. After analyzing a large number of diets, it seems apparent that most diets are severely lacking in nutrition.

    However, using the same program, I’ve seen that it is still possible to get all your nutrients from food. The program has designed palatable 2,500-3,000 calorie diets that provide all nutrients well in excess of the RDAs. In addition to getting a full spectrum of balanced minerals (anywhere from 100 to 200% of the RDA), it’s possible to get 300-2000% of your RDA for all vitamins from food alone.

    Since the USDA database is based on fairly recent analysis of foods, soil nutrient depletion is taken into account. This kind of diet would be hard for most people to follow, but it is basically a more specific version of the Bulletproof diet and Paleo/Primal diets.

    Can supplements still help? I definitely think so, and take some myself. But I think where possible, diet should be employed first and supplements added later based on needs indicated by personal analysis (like energy levels) and medical tests (like vitamin and mineral levels in the blood, inflammation markers, etc.). In many situations–for example, calcium and vitamin E supplementation–supplements seem to have an opposite and detrimental effect compared to consumption of the nutrient in food.

    so what supplements does a girl take that works on being lean but strong and overall super healthy! does moderate crossfit workouts weekly and yoga once a week. and someone who is aiming for a high quality of living. currently stocking the house with quality grassfed, wildcaught & pasture raised protein, organic fruits and vegetables, healthy fats from olive oil, avocado, mct oil, kerry gold, carlson’s fish oil and olives…lots of olives! also on the upgraded bulletproof coffee in the mornings and 14-17 hours of if’ing/day. would love some assistance!!! love learning about all this stuff! great journey so far!

      Have you think of detox your body? I know a lot of people lost weight after detox.

  • Ldyclements

    Thanks to reading the above, I feel alittlemore informed and a little more inclined to add supplements to my diet. Thank you so much!

  • Unless one raises their own vegetables and livestock, a shortage of nutrients is in the cards and supplements are needed to help close the gap. If some people don’t know the difference between “supplement” and “substitute” they will learn those definitions one way or another.

  • Great article, my 2 cents: I eat a strict form of Paleo by whole9life. Which all fits in the bulletproof diet. My meat is grass fed, wild caught, and/or compassionate certified. Eggs pastured. I grow a lot of my own veggies and get organic for those things I don’t grow. I drink BP Coffee every morning. But I still supplement. For one, Vitamin D. I don’t get enough sun, so I need it. I also take Magnesium and Potassium for the reasons mentioned in the article (I mainly drink filtered water) I also take krill and green lipped mussel oil because I would never eat those things but like to get a wide variety of omega 3. I also take certain enzymes like serrapeptase because I don’t eat japanese silk worms. And a few others I take for adrenal support because I don’t eat certain organ meats like adrenal glands. But I agree these are supplements, not excuses to eat like crap. That’s why I don’t take a multi-vitamin. I only supplement with things I feel I’m not getting enough of.

  • This is a great post about why to supplement, but most people reading this already believe the why.

    The better question is how? What’s a formulaic list of supplements most people should consume? And where can I go to get a blood test and determine exactly what I need?

      Chris, it’s common for my paleo caveman friends to think kale will somehow vitaminize them. 😉

    Well, I read and reread the posts stating that supplements are important, and it does sound convincing, but try as I might, I can’t find what supplements you’re talking about. Can you help me out with that?

    Thank you!

    • Dave Asprey

      That’s the topic of a whole book!

      D3, K2, CLO, magnesium, potassium, calcium-d-glucarate, ascorbic acid, collagen are a good start!

      • Andy H

        Hi Dave — Why do you recommend supplementing potassium? It is abundant in the food supply (fruits and veggies)

        • Dave Asprey

          Fruits aren’t a good idea because of fructose. Veggies may have potassium but it varies.

        • Curt Tigges

          From what research I’ve done, potassium supplements are highly regulated and generally are very low dose (the ones I’ve found have only 3% or less of the RDA). You’d need a lot of pills to make a difference.

          The best sources of potassium in the natural world are spinach, squash, avocados, coconut water, papaya, and various beans (but we know those are not good for other reasons). A single serving of any of those will only get you 15-25% of the way to your RDA, so it generally takes a combination of many vegetables. For comparison, though, you’d need about 6 potassium pills to compensate for one serving–and 33 to get the whole RDA.

          From what I understand, potassium is also generally replenished in the soil as it is a part of many fertilizers, so nutrient depletion isn’t as much of an issue.

        • UFOJason

          There is a Vitamin D with K2 supplement I know of. There’s also a Multi-mineral that I love 😀

  • Jay L

    Dave, can you suggest some additives to avoid in supplements? For example, what do you think of magnesium stearate, stearic acid, silica, silicon dioxide, microcrystalline cellulose, and the like? Also, what form(s) of magnesium you like to use as a supplement?

    Thanks a lot.

    • Use magnesium citrate, glycinate, or malate.

      There are a ton of additives, but that’s a good idea for a post.

      • Dave Asprey

        Or orotate or aspartate!

        • Jay L

          Thanks, Dave.

      • Jay L

        Thanks, Armi. I have heard bad stuff about several common supplement additives, so I’d very much like to hear your and Dave’s takes on them. It seems like it would be crazy to seek out high-quality grass-fed beef and butter, and then take supplements with industrially processed, toxic crap in them.

        • UFOJason

          I think another thing is to take supplements that are not in pill or capsule forms. This way, you’ll avoid the sweetener, binders, fillers, etc. that keeps them in pills or put them in capsules :)

  • Devon Slovensky

    The real question here is what do we really need? I don’t trust the RDA’s, some are too high and others are too low. So difficult to know what we need, particularly when some things are more important as a ratio than an absolute value.

    • Good question, I’ll start working on a post :)

      • Devon Slovensky

        Can’t wait to see what you come up with! I get all spun out thinking about it. D3:A, potassium:sodium, zinc:copper, omega 6:3. . . I could go on.

  • Er1kksen

    I’ve got fish oil, magnesium citrate and D3 in the cupboard, but ever since I discovered that my local beef farm (strictly grass-fed cows on soil I know is nutrient-rich) sells chopped marrow bones for a buck per pound and will save their hooves for me at no cost, I’ve been relying on that for most minerals and collagen. Scoop out a little marrow to eat raw, and the rest, as well as the bones and hooves, get boiled for a few days with some herbs (to safeguard against lipid oxidation) and vinegar. This gets a thick, rich stock. I cook with it often, and have a hot mug of it every night; I swear ever since I started I pop out of bed every morning ready to go. Maybe I’m lucky to have access to the farmers I do, but when you CAN get the nutrition via diet, I suspect that’s the best way to go. All the “right” pills never hit me the same way as good stock does.

    • cogrick2

      That’s an inspiring account. I wonder if I can find marrow bones around where I live…

    • Anon

      care to share your stock recipe? what kind of herbs?

    • Rod

      I would assume there are other nutrients/vitamins that aid absorption and a combination of them are helping you. Perhaps a placebo? maybe not but thanks for sharing that.

      • Dean Zhao

        Digestive enzymes help absorption. Also, many benefits from digestive enzymes. Google it., I now which brand is one of the best.

  • 2 Meal Mike

    I would say adding in “bone broth” (or beef broth) is the ideal way to get what you need in minerals along with the most bio-absorptive state.

    Isolating supplements are a crap shoot, you don’t know if your body is really using them or if you are lacking other necessary vitamins/minerals for maximum absorption.

    Antioxidants should be avoided as a supplement, as they have been shown to decrease the body’s (and mitochondria) ability to reduce/protect against free radicals on it’s own (mitohormesis). They make for great marketing, but the reality of their use seems to be quite different.

    Higher quality/nutrient dense real food should always be the long term focus and use supplements to help “correct” a temporary imbalance.

    • Rod

      Could anyone elaborate on “Antioxidants” please? What are some examples of “Antioxidant supplements”? You suggest “using supplements to help “correct” a temporary imbalance” are you saying this while knowing that we are in fixed variables that require us to consistently supplement? How would one fix a Vitamin D deficency temporarily if they are always indoors and hiding from the sun? This is just one example but you know where I’m going with this. Thanks.

      • Dean Zhao

        I think I always need antioxidant. I give it to my children too. Instead of visiting doctor office every week. My children visit once a year. Antioxidant keep me young and strong.
        One of the most powerful antioxidant is OPC and astaxanthin.

    I firmly believe in supplements. When you have the experience that I had, you would as well. I doubt that proper eating would have saved my grandfather from an advanced stage cancer. He followed instructions from the doctors, did chemo, and everything else just the same as others from his same age group with the same stage of the same cancer. The only thing different was he was taking these supplements, and out of all those people, he is the only one that is still breathing, now cancer free. Because of that, I would not leave the house in the morning without my daily supplement cocktail.

    Under #3 it says, water filters remove magnesium. Then further down the paragraph it says if you are not using a water filter than you are likely to be deficient in magnesium.. Is it just me or is this contradictory? Am I missing something?

    • Rod

      Hey Devon,

      I was thinking the same thing. I just don’t know why we would be.

      Dave? Can you please elaborate?

      If you don’t use a filter and you don’t have a well, it’s likely you’re consuming dangerous amounts of fluoride and/or are deficient in magnesium. <-= why?

    • Richard Ayoub

      Distilled or purified and reverse osmosis water is ‘Dead” water, it has no mineral electrolytes and that’s what the body runs on. Every time you drink a drop of this types of waters, your body has to go and get alkaline minerals from your bones and organs to buffer the acidity of these water and process it. so the more you drink waters like these the more mineral deficient you become and eventually tired and sick.
      Best water are Natural Mineral/Spring Waters with an 8-8.5pH.

I also think Pepsi and Coca Cola should be also to add cocaine into their drinks, why not they need to make money too, the medical industry isn’t god of all businesses. When my kidnapping children business starts making more money than the government, I’m gonna bribe them, get them to change the laws and make the laws say it’s okay to kidnap children so my business can grow even bigger. hahaha one day, stupid world.

    So for thousands of years before supplements we have been doing a dis-service to our bodies with “real food” Damn, I’m sure pre-historic man was craving some vitamin D pills after he slayed that Mastadon!

  • Morgan Bookheimer

    Most of this is dangerously misinformed.

    What about organic salmon/fish? Bio/Organic or free range Chicken is high on omega 3 to, but is a no go because there use grain to feed them? And serious how could anyone with a normal budget survive on this kind of diet, without having a big land to grow there own greens? I find i hard to crack the code. I like the philosophy, bulletproof diet, and most of the thing your say are very interesting and many people know, but ignore, because we live in a state of willful ignorance. I still find it a little hard to swallow, that we have to use supplements.

  • Excellent article. I think it gives a definitive answer on supplements. Today is not the same as 10 years go let alone 50. Our culture is changing the way we eat and what we eat. Unfortunately for every action there is a reaction, we as humans need to be proactive in our health more than ever.

    You should become an attractive person with uses of supplements products of body buildings.

  • Its really a good information to share and I personally feel If you’re focused on losing body fat or increasing the amount of lean muscle tissue you have to take care of your total calorie, carb, protein, and dietary fat intake. If you are including supplements in you body its all important but you have to take care of correct one that are all natural supplement and help your body in the positive way. Just make the correct choice is important.

    Where did you get the idea that grain is not food? In the bible it says God fed them with the finest of wheat. But, you know better than God. Maybe He should consult you!

  • Guest

    First of all, exercise doesn’t increase the micronutrients such as vitamins and minerals since vitamins and minerals are not an energy source (no calories). Supplements are bullshit.

    Did you really try to argue that supplements are healthier then real food? Seriously… wow… who’s paying you off

  • Very good summary. I’d perhaps add that many fruits and vegetables have had their nutrition bred out of them in order to offer sweeter products…

  • Health Nut

    I found a great supplement that combines a multi, fish oil, probiotic, and whole food blend all into one soft gel! Basically, if you’re taking 3-5 products, chances are, this is the only one you need to take! The company is called Encompass Nutrients and the product is Complete Adult. Here’s a link. http://www.encompassnutrients.com/store Best part is that they give 80% of their profits to care for orphans! Awesome company!

  • Thank you for sharing us your thoughts. A very informative and exact facts you gave. I can recommend to take a supplement that is highest rated and quality guarantee among all 1700 supplements in the market, with fast absorption rate in our body…we knew,,not all supplements are made equal, and not all supplements give what our body needs, right?..So better to take effective, potent and safe supplements. You also mention about athletes, yes..they trust this and used the product!. The only supplement that give them quality standard…..check this put. http://www.zorrobabelle.usana.com

    That’s a great article very well written and some good facts in there! But you need to be aware, when taking suppliments that they are from a good source. For example, if you take normal mineral products these will most likely be chelated minerals, made from powdered rock and other materials which your body cannot absorb, it will absorb some of them but the rest will get stuck in your body creating little pockets of rock and metals that can go toxic. This is why we need to be eating plant derived minerals, with them being 7000 times smaller than a blood cell your body will absorb 100% of them and dispose of what it does not need.

    12. The RDA/RDI levels are the minimum amounts needed to prevent nutritional deficient diseases. For optimal health we need more than those amounts. For some nutrients we may only need just a bit more but others require much more to have optimal health.

  • Denise Brown

    Although I agree with most points made in this article, I find some debatable unless you are an avid follower of the Paleo diet. I recommend that people ALWAYS consider their own bio-individuality when choosing what to eat and what to supplement with. The strongest and well-documented reason for supplementation is the fact that a lot of the plants we eat are grown in mineral deficient soils…even organic produce. If you buy organic hopefully it is local and you can find out directly from the farmer/ gardener how she amends the soil and what organic methods are used such as crop rotation and companion planting.

    So if you are using lots of picture in developing, every time it is required to adding ALT tag to describe a summary about the picture. In Alt tag you can also use keywords and phrases or keywords and phrases but keep in mind about keywords and phrases stuffing. traditional curtain fabric

    Most if not all supplements are man made – I would prefer to have something provided by nature – superfoods that are still live, organic and NON-gmo is my first choice – the body can easily digest and utilize them easily. They feed the body at a cellular level and the results people can when they incorporate them are awesome – feeding the body is different than eating food and supplements that are synthetic can’t do it.

  • The taking of supplements is more a religion that a science. You either believe in it or you don’t. I don’t. Also, like any religion some people make an awful lot of money out of it.

  • Lisette Cousineau Sleno

    what a great article, everything I am saying all in one paper.I also like what Sean added.

  • RYAN

    This is the biggest pile of BS I’ve seen in a while. Dave Asprey should be ashamed of his stupidity. Anyone that understands real science can read right through this BS, but sadly so many people fall for this.

  • It is good if you have results from a third party that has studied particular supplements. This was done for the Peak Performance Pack, that uses a patented delivery system. Learn more at freiburgstudy.com

    great article – you just have 1 paragraph repeated in your content. twice in point 7.
    ” Our bodies weren’t designed to deal with these toxins using only nutrition from food. They just weren’t. So if you plan to get your nutrition only from food, you should plan to get your toxins only from the Garden of Eden. Good luck with that.

  • Ray Treadaway

    A great article and darn good read……… make sense regardless which country you’re living in………….. I note some of the contributors here are asking after what supplements to take……….. My suggestions is to take a supplement is a multi-vitamin/mineral as vitamins on their own ‘don’t cut it’ (unless they have minerals) with them………. if anyone would like some info contact me direct via: [email protected]

  • Nora Rodriguez

    I absolutely agree. I just turned 50 years old and I knew I had to do something different to feel better. Because our soil is so depleted, crop grown does not have the proper vitamins/minerals we need. I started taking Peak Performance by Melaleuca The Wellness Company, because they have an 85% absorption rate, proven effective, Freiburg Study for the consumer viewing and I feel great! If you would like more information, please contact me at [email protected]. I can send you a Freiburg study for your viewing. Thank you.

    As a certified Nutritional Therapy Practitioner, what I see mostly with my clients is a failure to secure enough nutrient-dense foods due to busy, stressful lives packed with personal and professional activities. So while your crowd here seems to be the exception to that in a few important ways – well-informed, well-advised, and highly incentivized, which today I find to be absolutely NOT the norm “out there.” For that reason alone (and there are several important others, several of which have been elucidated in this well-written article), it’s crucial that people augment their diet with nutritional supplementation. But then the question becomes, what constitutes supplementation worth the expense, because let’s face it, high-quality supplements ain’t cheap! And there’s a WIDE variance in quality among products, and most ppl’s choices are driven by cost. Suffice it to say that the vast majority of ppl have no idea where their nutritional status stands (e.g. low priority, moderate priority, high priority). Taking a supplement in which you’re already sufficient is as unhealthy as not taking a supplement in which you are deficient. So without some sort of basic nutritional assessment (i.e asking your body via a series of well-designed questions; most blood work doesn’t give an adequate nutritional assessment), you’re flying blind. I’m fortunate in that I have such a questionnaire at my disposal, and with it I’m able to accurately gauge my client’s progress through the course of their supplementation regimen. Verifiable facts baby, and that’s not me telling them, that’s their body telling me!

    I take all forms of supplements. Mostly Essential fatty acids, amino acids and fibre. My daily supplement intake exceeds 15 different nutrients on a daily basis. As a result I’ve become sharper, better physically fit and my cardiovascular health has GREATLY improved. MY top recommendations: Omega 3, COQ10, L-theanine, L-tyrosine, creatin, Astaxanthin (with lutein and zeaxanthin), Vit. B100 complex, zinc (with magnesium), glucosamine sulfate, fibre, vitamin D (with calcium), and an amino acid complex. Everything else I more or less get from my diet

  • Now a days if you’re only looking to get all the extra proteins from your food then you’re doing something bad. I have totally satisfied with the Author points of view that there are some bad farming techniques which keep the nutrient value away from the farm product. Thanks for sharing all this.

  • Abcde

    I agree. But its also hard to known for sure WHICH nutrients we lack. Supplementing individual nutrients may not be so useful. Better to use an all-encompassing multi-vitamin multi-mineral tablet to fill in any unknown holes.

  • Jackie Debin

    I am concerned about the recommendation in the BulletProof Diet about taking Vitamin C ASCORBIC ACID CRYSTALS. When researching Vitamin C supplementation there are article after article warning against the Ascorbic Acid form. It is a GMO and is not good for you. Dave can you clear this up and explain why you recommend this type of Vitamin C?
