Effects of Food Intake and Anoxia upon Ascorbic Acid Excretion, Acidity of Urine, and Survival of Male Albino Rats

Effect of High Carbohydrate, Protein, and Fat Diets and High Altitude on Growth and Caloric Intake of Rats

“…A1 though growth retardation occurs at altitude regardless of diet, the present study shows this effect was markedly enhanced when a high protein diet was fed. Other detrimental effects of high protein diets have been shown previously by Langwill et al (9) using hypoxic survival rate of rats as the criteria and by King et al (11) who measured psychomotor performance in hypoxic humans. Chinn et al (1) exposed rats to moderate altitude (3475 m) and fed diets similar to those used in our study.…”

“…I n a recent study, rats fed diets high in either carbohydrate, protein, or fat were found to consume fewer calories and grow at a slower rate when exposed to moderate altitude (3475 m), but neither altitude nor diet had any effect on the efficiency of food utilization for growth (1). Earlier animal studies indicated high carbohydrate diets may afford measurable protection against anoxia ( 8 ) ; whereas, diets high in protein (9) or fat (10) seem to have detrimental effects. Similar observations have been made during altitude tolerance studies with humans (11).…”
