The height of caloric norms depends primarily on the type of work and lifestyle. The heavier physical work, This standards should be higher, which may come to 4500 kcal. Similarly, standards for pregnant and lactating women outweigh the standards for moderately working women. Adolescent youth should also receive food of high caloric value, because this period is not only a growth period, but also high physical activity. Whether the demand for energy supplied with food is satisfied at the appropriate level, It is easy to control by frequent determination of body weight. U ludzi dorosłych nie powinno być znaczniejszych wahań. Ciężar ciała u dzieci i młodzieży musi charakteryzować się harmonijnym wzrostem (table 3).
Admittedly, detailed caloric norms for individual population groups are developed, But they have this disadvantage for us, that they are developed for the so -called. average in a given population and practically for individual nutrition are not decisive.
Let us remind you, that decisive for proper nutrition, is to include in the diet all nutrients in the appropriate proportions for the body.
To facilitate the calculation of energy, which we can get a human system from food, we accept, that the energy value of proteins and carbohydrates is the same 4 kcal (17 kJ) na 1 g of the component supplied to the body. Fat provides OK. 2,5 more energy than protein and carbohydrates, i.e.. oxidation 1 g fat is accompanied by obtaining 9 kcal energii (39 kJ).
