Abstract : The effects of three diets (high-carbohydrate, high-fat and high-protein) and two altitudes (11,400 ft. and 14,110 ft.) on growth and food consumption of young growing rats were studied. Growth was slightly depressed at 11,400 feet and markedly (P<0.001) depressed at 14,110 feet. Rats appeared to grow better at both altitudes when fed a high-fat diet. The type of diet, however, is not a major factor affecting growth at high altitude. Food consumption was significantly (P<0.001) depressed at 11,400 feet but no differences in food utilization were observed. On the other hand, food consumption was decreased (P<0.05) at 14,110 feet in rats fed a high-protein or high-carbohydrate diet but not in rats fed a high-fat diet. However, food utilization was significantly (P<0.001) decreased. It appears likely that depressed growth at high altitude can be traced to metabolic derangement resulting from the combined factor of diet and altitude. (Author)
