Nutritional Supplements – Who Needs Them?

It is often said that food is the best source of nutrients and this is a fair statement. Nutrients in food are generally more bioavailable than nutrients in supplements. Food also undoubtedly contains micronutrients that have not yet been identified by scientists and are vital for good health.

That said, I believe that supplements are valuable as a kind of insurance policy to ensure that you are getting enough vitamins, minerals, antioxidants and trace elements from your diet.

This can be important for maintaining a healthy weight. If a person does not get the right nutrients, the body compensates by making you want to eat more to supply the missing nutrients.

But the question arises, if you eat a balanced diet, why are you not getting enough nutrients? There are many reasons. Let’s start with the most obvious.

MODERN DIET

The modern diet consists largely of grains, beans and roots. Compared to plants that grow above the ground, fruits, nuts and lean sources of protein, these food sources are low in vitamins and minerals.

To make matters worse, over the past fifty years more and more of our food has become increasingly processed, eliminating what little nutritional value it may have had. McDonald’s burger, anyone?

LIFESTYLE ISSUES

When you smoke, you are consuming vitamins and minerals that are cannibalized by the chemical processes inherent in smoking. This is because smoking produces large amounts of oxygen-free radicals. Nutrients such as vitamin A, E and C are used by the body to neutralize these free radicals and are thus depleted.

An animal study published by the American Society for Nutrition showed that smoking caused vitamin A depletion, leading to emphysema.

Also, in a study at Columbia University in New York, smokers and non-smokers were given vitamin C and E supplements and their plasma levels were checked for 6 days. The researchers concluded that smoking depletes vitamin C and E.

Recreational drugs such as marijuana, speed, crack, heroin, and alcohol can have a similar vitamin-depleting effect.

FOOD RADIATION

Today, foods are irradiated to extend their shelf life. According to a report by the FAP/IAEA/WHO Joint Study Group, it causes the loss of nutrients, especially vitamin B1, vitamin C, vitamin E, vitamin A, vitamin D and vitamin K, vitamin B6, vitamin B2 and vitamin K. B12. In addition, this effect is exacerbated by the longer shelf life of these foods.

ENVIRONMENTAL POLLUTION

Industrial pollution causes the formation of free radicals, which can cause cell damage, which is one of the main causes of premature aging. While there isn’t much you can do about pollution, taking antioxidants can help fight free radicals. For example, a review of randomized controlled trials published in Ophthalmic and Physiological Optics by the College of Optometrists found that taking antioxidant supplements reduced the incidence and/or severity of macular degeneration, the leading cause of vision loss in people over 1 year of age. 50 years in the developed world. This is not surprising given that oxidation is thought to be at least partially responsible for many degenerative eye diseases.

PESTICIDES

Pesticides, widely used in agriculture to control pests, reduce the nutritional value of crops. A review of 41 published studies by nutritionist Virginia Worthington found that organic crops (which do not use pesticides) had 27% more vitamin C, 29.3% more magnesium, 13.6% more phosphorus and 21.1% more iron than their conventionally grown counterparts. colleagues.

SOIL DEPLETION

According to a study by David Thomas, the mineral content of US farm soils declined significantly between 1940 and 1991, with vegetables harvested in 1991 having 76% less copper, 46% less calcium, 27% less iron, and 24% less iron. magnesium than their 1940 counterparts (Nutrition and Health 2003; 17: 85-115).

Why did this happen? According to Dr. William A. Albrecht, head of the Department of Soils at the University of Missouri, NPK formulas, as legislated and enforced by state departments of agriculture, mean malnutrition, insect, bacterial and fungal attack, weed proliferation, and crop failure. loss in dry weather and a general loss of mental acuity in the population leading to degenerative metabolic disease and early death.

By NPK formulas, Dr. Albrecht is referring to the use of inorganic fertilizers common since the 1920s, consisting primarily of nitrogen, phosphorus, and potassium, with occasional additions of calcium and iron. Important trace elements that would be replaced by the use of organic fertilizers never return to the soil.

SUMMARY

As you can see, there are many reasons why simply eating a balanced diet is not enough to ensure adequate nutrition for a person. The quality of food is not the same as it was even 50 years ago, and modern environmental and lifestyle factors can also deplete our bodies of nutrients.

Therefore, it is a good idea to take supplements to ensure adequate nutrition.
