[Energy and food stuff requirements and actual nutrition of foreign students studying in the USSR].

The actual nutrition of students of the Patrice Lumumba University of Peoples' Friendship, who had come to the USSR from different countries of the world, was investigated during their studies. Insufficient content of vegetable proteins and fats, Ca and vitamin C, as well as low carbohydrate level were detected in the food of students from all the continents, except for Asia. No significant difference was observed between the energy providing with food and its consumption by the students.

[Use of fructose as an energy substrate in the body of rats given food containing various amounts of carbohydrate].

Production of radioactive CO2 from 14C-fructose administered intraperitoneally was studied in 18 male Wistar rats given food containing saccharose with calorific value of 0-56%. Intensive CO2 labeling was completed 3-4 h after 14C-fructose administration. More radioactive CO2 was formed in rats which received food without fructose, during first 30-60 min after 14C-fructose administration.

[Energy expenditure of students at the Patrice Lumumba People's Friendship University during classes].

Energy expenditures were studied in 68 first- and fourth-year male students of the Medical Department of the Patrice Lumumba University of Peoples' Friendship, who arrived to Moscow from different regions of the world: Asia, Africa, Latin America, the Middle East, the Near East, and from the USSR. The measurement of the energy expenditures was conducted at rest, when they sat reading special literature, or stood at the blackboard solving mathematical problems, and during walking at a rate of 4 km/h, applying indirect calorimetry according to the rate of the intake of oxygen and the output of carbon dioxide, with the use of Douglas-Haldane's apparatus and automatic gas analyzer. It was established that the mean values of energy expenditure per 1 kg bw during varying types of activity did not significantly differ in students of various nationalities from different regions: daily energy expenditures of students from the USSR comprised 2591 kcal, from Asia--2240 kcal, from Africa--2296 kcal, from Latin America--2470 kcal, from the Middle and the Near East--2399 kcal.
