Physiological norms of a food

Now in Soviet Union physiological norms of a food for adult able-bodied population taking into account intensity of work are accepted. All population is conditionally divided into five basic professional groups:

I group - the persons who are engaged mainly in brainwork (heads of the enterprises and the organisations, technical structure, workers of planning and the account, sokretari, operators, dispatchers, etc.);

II group - the people who are carrying out easy physical work (the workers occupied on automated processes, sewers, etc.);

III group - workers of an average on weight of work (the machine operators occupied in metallo - and derevoobrabotke, mechanics, servicemen, adjusters, workers of the food and chemical industry, printers, etc.);

IV group - workers of heavy physical work (builders, machine operators, miners, workers oil, gas, a pulp and paper industry, metallurgists, founders, etc.);

V group - the people who are carrying out the heaviest physical work (the miners used directly

On underground works, steelmakers, loaders and the workers occupied in manufacture of building materials which work is not mechanised).

Energy sources are carbohydrates, fibers and fats. In a diet they should be balanced in certain parities. The parity of fibers, fats and the carbohydrates, equal 1:1:4 is optimum. The offered formula of equation of the basic food substances considers a close connection of normalised substance with power value of a daily diet.

Now, when character of physical work has radically changed in connection with mechanisation and automation of productions and physical work has closely come nearer to work intellectual, and also the physical activity share in a life has changed, the principle of equation of the basic food substances resulted above requires updating. It first of all concerns carbohydrates and fats. The parity of fibers, fats and carbohydrates thus is accepted as 1: 2,7: 4,6 on power value.

Power value of a diet is established depending on age and a floor. Dependence of power value of a diet on intensity of work (V group) is especially appreciable. Than more movably a way of life, the more the person works physically, the it is necessary to limit power value of a food less. At an inactive way of life and especially at superfluous weight of a body of the person it is necessary to limit power value of a diet.
