Nutritional Supplements: Do We Need Them?
According to the World Food Organization ...
... as dietary supplements we consider the additional substances we take to ensure the smooth functioning of our body, when it disturbed or when we want to prevent any possible disturbance.
It should be noted that almost all natural supplements contain substances that are alone or are intermediate products of biochemical processes in the human body, unlike what happens with the vast majority of drugs.
This is why nutritional supplements are considered much safer than drugs. Proof is, that the World Health Organization has established stringent, costly and lengthy procedures to give authorization to a drug, while the supplements are classified as food, for which the procedures are much simpler.
Many diseases are caused by a deficiency of vitamin, trace elements or antioxidants. For example, zinc deficiency caused approximately 30 mental and physical illnesses such as mental disturbance, photophobia, nerve anorexia or excessive appetite, abnormalities in taste and smell, various skin diseases, ulcers, delayed development, sexual immaturity, weakening of the immune system and others.
While the adequacy of another trace element, selenium, among others, strengthens the immune system, protect us from infections, caligo lentis (cascade), premature aging and more. Last confirmed that it is also very effective in prevention of cancer.
Deficiencies of vitamins or trace elements can be caused by various causes, and even medicines. For example, tetracycline, a known antibiotic, prevents the absorption of calcium, magnesium, potassium, zinc and iron and blocks the concentration of vitamin B. Contraceptives reduce the water soluble vitamins, magnesium and zinc. Antacids prevent especially the calcium absorption and the abuse of alcohol reduces the absorption of several dietaries.
Also, it is undisputed that most elderly people, even those not suffering from any disease, need dietary supplements because of their inability to assimilate the nutrients in foods.
The World Health Organization assures us that the diet of thousands of people, even in economically thriving communities, has a lack of vitamins and minerals. Indicative of this finding is that 75% of the U.S. citizens, either occasionally or on a permanent basis, take nutritional supplements.
