In principle, natural foods, taken in their proper proportions, ensure nutritional balance, and therefore good health. However, nowadays it is increasingly difficult to maintain.
Indeed, even though it is varied, the modern diet cannot provide all the essential nutrients in sufficient quantities. To achieve the desired goal, we should consume at least 3000 calories a day which, given the sedentary lifestyle we have, would lead us to obesity.
In addition, the nutritional value of food is less every day.
Certain factors aggravate the deficiencies of the modern diet:
• The monotonous and small variety of food available, such as that found in a rigorous weight-loss diet
• Circumstances that increase nutritional requirements: growth and puberty, pregnancy and lactation, the intensive practice of physical exercise, etc...
The result of all this is an insufficient supply of certain nutrients that our body needs: the micronutrients.
The so-called "micronutrients" – although only required in small amounts - are indispensable for the proper functioning of our body. Specifically, micronutrients allow adequate absorption and proper utilization of protein, carbohydrates, and lipids, which provide the energy required by our body for all its activities.
Among the micronutrients we find:
• Vitamins - vitamin B for the equilibrium of the nervous system, vitamin C to reinforce the immune system, vitamin D for bones and the protection against viruses, vitamin E to prevent oxidation.
• Minerals - magnesium, iron, calcium for bones.
• Antioxidants - carotenoids and polyphenols, such as the famous resveratrol, to prevent premature aging by fighting the free radicals generated naturally by our body through the exposure to oxygen, to the sun, and all of the toxic substances we use.
• Essential fatty acids, such as Omega 3 DHA and EPA, which guarantee the plasticity of cell membranes.
• Specific amino acids, which play a fundamental role in the immune system and constitute the base of the genetic code; some of them - Tirosine and Tryptophan - help to regulate mood, sleep, and satiation.
• Probiotics - live micro-organisms which, ingested in appropriate amounts, help to strengthen and regenerate our intestinal flora to increase our defenses.
THE NECESSITY OF MICRONUTRITIONAL SUPPLEMENTATION
For the most part, micronutrients cannot be manufactured by our body. Hence the importance of a diet that ensures an adequate intake of them all. It is advisable to complement our diet with supplements which provide appropriate levels of micronutrients since today our consumption of them is often inadequate and of poor quality.
Finally, although micronutrition is useful in the treatments of "anti-aging" and aesthetic medicine, prescribing these supplements should not be taken lightly. As we have seen, micronutrients are imperative for the proper functioning of the body, and therefore, they must not be administered lightly. It is best to consult a medical specialist.
