Many vitamins are not synthesized in the body and come only with food. The daily need for them does not exceed a few thousandths, hundredths of a gram. Vitamins are very unstable and are destroyed during cooking. The lack of vitamins in food can lead to severe disorders in the body, which are now rare. Often there is a decrease in the provision of the body with certain vitamins (hypovitaminosis).
