Body needs all nutrients: proteins, fats, carbohydrates, vitamins and mineral salts. Extracted from the product under the action of digestive juices, and getting soaked in blood, they spread to all organs, which go to form, the restoration of the various cell elements consumed by man and replenishment of energy. We can not live, for example, without the proteins that make up the structural framework of cells, are part of enzymes, hormones, nucleoproteins, fibrin, and many other vital substances. Nevertheless, such a valuable protein product, like meat, eat only if they can prove harmful for the body.
Found in meat biogenic amines can enhance the tone of blood vessels and thereby increase blood pressure, and nucleic acids and purine bases – cause the development of gout. James A.

In general, insufficient and unbalanced diet accelerates the aging process – this is the conclusion of scientists of the Institute of Natural Resources of Japan Science and Technology management. Having studied the lives of thousands of three people aged over 65 years, they found a direct relationship between diet and physical activity levels, which was chosen by them as the main indicator of age. individual foods and dishes from them. Some, for example, do not eat milk, while others – the fish, and others – fruits, etc. In this way they put your body in very adverse conditions, permanently depriving it of essential nutrients. Institute nutrition have developed specific values of physiological needs for nutrients and energy. In line with these recommendations, caloric intake adult working population is normalized to Depending on the intensity of labor.
