Deficiency of vitamins and a number of minerals inevitably leads to disturbances in metabolic processes and physiological functions and, as a consequence, to poor health, a decrease in the body’s defenses, and the development of vitamin deficiency diseases. Prevention of vitamin deficiency consists in ensuring full correspondence between human needs for vitamins and their intake with food. The entire set of vitamins necessary for a person can enter the body only if all food groups are used in the diet. Mechanization and automation of the labor process made work easier and reduced energy costs, however the work of firefighters-rescuers has become much more difficult, tense and dangerous. Rescue work is dangerous and requires trusting cooperation - a wrong decision or behavior can endanger the health and life of the rescuer himself, his team, and others. Based on the results of the work, a conclusion was made about the undoubted physiological and energy value of an instant granular drink based on concentrated curd whey and fruit and berry raw materials, as well as the need for its introduction into the diet of firefighters-rescuers, to ensure the normal course of life processes in the body, and mainly for prevention of vitamin deficiency.
