[Food caloric value and the energy requirements of students].

Over a month a group of 65 practically healthy medical students, leading a usual life, received diets according to the apportionment elaborated in agreement with "Recommended Values of Food and Energy Physiological Requirements" (1968). From daily measurement of body weight it was established that normally the weight got stabilized after two weeks' elapse from the commencement of observation. The caloric value of the food taken was assessed in 16 subjects under test. The daily caloric value of the food amounted on the average to 2980.10 +/- 88.18 kcal. i.e. it was 10% less as compared to the recommended energy requirement rates of male students. From previously reported data on protein metabolism and parameters of working capacity recorded in the same persons under observation it is concluded that the caloric value of the food taken equal to 2980.10 +/- 88.18 kcal is quite enough to replace energy losses of the students.
