Micronutrients

Several other food components that have been linked positively in favor of cancer prevention are called micronutrients, because the amount you eat of them in the daily diet is small, a few milligrams and sometimes less. They are mainly folic acid, calcium and antioxidants known as micronutrients, most clearly demonstrated its protective effect against cancer: vitamins A, retinoids and beta-carotene, C and E and selenium.

The richest sources of these micronutrient antioxidants are fruits and vegetables. A low intake of these compounds was associated with increased incidence of lung, oral cavity, pharynx, larynx, esophagus, stomach, colon, rectum, bladder and cervix.

Special attention is being paid to them retinoids (preformed vitamin A), which is found mainly in the liver, egg yolk and animal products and even more carotenoids (provitamin A), in particular beta-carotene is found in vegetables and fruits, dark green and orange.

Beta-carotene appears to exert its protective effect against cancers of the lung, esophagus, stomach, colon and rectum, prostate, breast, cervix, ovary and skin. Its main advantage over retonoides is that an increase in their consumption or as a capsule supplementation does not cause problems of hypervitaminosis A. In addition, its utility is investigating preventive treatment in different types of cancer by nearly a dozen international studies.

Returning to practice in respect of these compounds, it seems advisable to increase consumption of foods rich in micronutrients such as plants, vegetables, grains and fruits and milk and its derivatives.
