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.
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. Taking multivitamins often make people think they can eat even worse, which isn’t exactly productive.
In any case, you’re not dead yet, so you must be getting the right nutrients. Supplements are unnecessary… right?
11 Reasons You Should Take Supplements
1. You Eat Crap a Standard 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.
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. 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 is Depleted of Minerals
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
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.
According to this study most diets require 27,575 calories to supply all the essential micronutrients. If you’re eating less than that, you’re deficient in 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 also evidence that glyphosate – RoundUp herbicide – chelates minerals in crops on which it is sprayed. It’s safe to avoid GMO foods for a variety of other reasons.
6. Grain-fed Meat & Conventional Dairy
Compared to grass-fed meat, grain-fed meat is abysmally low in antioxidants, micronutrients, fatty acids, minerals, and vitamins.
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:
- Xenoestrogens (plastics, BPA, some molds, petroleum products).
- Industrial solvents and cleaners.
- Unnatural lighting
- Food toxins.
- 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.
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). 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.
10. Supplementation May Help You Live Longer
Aging is a natural process, but being ancient may not be fun. If there are supplements than can delay this process, why not take them? There is good reason to believe a higher intake of nutrients may prolong life. If supplements can buy you a few more years of quality life, why not take them?
11. Expense & Health
Taking care of our health is the best health insurance there is. Staying healthy and productive, free of health worries, is any day cheaper than expensive treatments for avoidable diseases.
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 sand won’t make the effects of these toxins go away. Neither will eating some vegetables.
