[Principle of determining the human requirements for basic foodstuffs in relation to climatic conditions].

A nomographic method is described for determination of the mans requirements of proteins, fats and carbohydrates depending on the climatic factor and physical activity. The authors propose that the principle of the territorial division of the country into climatic zones be used for a differentiated study of the influence of climatic factors on the human body. A mathematical principle of the assessment of the man's requirement of the main foodstuffs has been developed, based on the physiological correlation of proteins, fats and carbohydrates according to to their calorific value (14:27:59). The method proposed allows the assessment of the requirement of food for a person, or different groups of the population with respect to their environment (climatic conditions) and physical activity.
