The work's objective is to analyze quality rating of diets from the standpoint of physiological need norms of a person and a daily ration, to further determine the balance of nutrition.Materials and methods. The daily ration of human nutrition (breakfast, lunch, dinner) and the norms of the physiological needs of the average person -to determine the complex quantitative assessment of the quality of diets. An additive mathematical model as most widespread in a qualimetry is used for joining the quality rating into the generalized (complex) index. Methods -qualimetric.Results and discussion. Taking into account the norms of physiological needs of a common person, the complexquantitative estimation of quality of one meal is calculated, the three-level hierarchical structure of the system of qualitative indexes is developed: the third level simple indexes are grouped in the qualitative indexes, which form the second level of structure systems hierarchy, which, in turn, form the first level, and then -in the complex index of zero level, which characterizes quality rating of diets.Basic qualitative indexes (Р basic ) of macronutrients, mineral matters and vitamins are the following: for proteins -0,15; fats -0,17; carbohydrates -0,68; sodium -0,45; potassium -0,34; calcium -0,07; magnesium -0,03; phosphorus -0,11; thiamine -0,02; ribofflavinum -0,02; perydoxine -0,02; cevitamic acid -0,94. Weight coefficients (m) are the following: proteins -0,50; fats -0,40; carbohydrates -0,10; sodium -0,03; potassium -0,05; calcium -0,25; magnesium -0,50; phosphorus -0,17; thiamine -0,36; ribofflavinum -0,32; perydoxine -0,31; cevitamic acid -0,01. The biggest value of the complex index (К 0 ) is obtained in breakfast -1,60, the lowest value is typical for supper -1,09.Conclusion. For the set daily ration, the complex qualitative indexes for the group of macronutrients, mineral matters and vitamins are determined. The most balanced values of qualitative index are set, that is typical for a supper №2 with the estimation -1,09.
