The proposed monograph "Baby Dietary Nutrition" by L.I. Rezvinova reflects the main modern trends in dietary baby food. Recommendations are given on the organization of nutrition for children in various diseases. The most important tasks of dietary nutrition are to prevent or eliminate violations in the supply of the body with necessary substances. Such "failures" of metabolic reactions often cause a chronic disease. Food is one of the sources of life, and to ensure the therapeutic effect of food, the child's diet should include - in the required amount and in the correct ratio - proteins, fats, carbohydrates, vitamins, minerals and water.
