ABSTRACT
The actual nutrition and providing with vitamins C and B1 was studied in boys aged 16-17 years, students of a rural trade school (Volsk of Saratov Province). Although the caloric value of their ration was high enough the content of animal proteins was only 42-48 g/day. The content of ascorbic acid in the ration comprised 48%, in the spring of 1987 it was 17%, and of 1988-29% of the recommended standard, vitamin B1 levels did not show seasonal differences. Vitamin C and B1 deficiencies in the spring were proved by their low excretion levels in urine, and by a low concentration of vitamin C and decreased activity of B1-dependent enzyme transketolase in the blood. Intake of "Undevitum" (1 dragee/day) during 4 months was conductive to the improvement of the student providing with vitamins.

Actual nutrition and providing with vitamins C and B1 were studied in students of rural trade school (youths aged 16-17 years) in the town of Volsk, the Saratov region. The actual nutrition was corrected by inclusion of curds and other milk and vegetable products into the ration. The content of ascorbic acid in the usual and corrected rations, estimated analytically, during spring comprised 17 and 29%, and vitamin B1--49 and 75% of the recommended standard. The insufficient providing of the students with vitamins C and B1 in spring was confirmed by their low level of excretion with urine, and by lowered vitamin C concentration and activity of vitamin B1-dependent enzyme transketolase in the blood of the investigated students. The ration correction improved to a certain extent the values of providing with vitamins C and B1 but could not eliminate vitamin deficiency. Administration of "Undevitum" in a dose of 1 dragee/day during 4 months eliminated the vitamin deficiency in the ration and provided optimum vitamin levels for the students.

Actual nutrition and providing with vitamins C and B1 was studied in boys aged 16-17 years--students of a rural trade school in the town of Volsk, the Saratov region. Although the fuel value of their ration was sufficient (2900-3000 Kcal), the content of animal proteins comprised at an average 42 g/day. The content of ascorbic acid in the ration (evaluated by the analytical method) comprised 48% (in autumn) and 17% (in spring) of the recommended standard; the level of vitamin B1 did not differ depending on the season on the year. In spring, vitamin C and B1 deficiency detected in the students was proved by their low excretion with urine, as well as by a lowered level of vitamin C and low activity of B1-dependent transketolase enzyme in the blood of the subjects studied.
