Ten young adults were divided into an exercising group (n = 6) and sedentary group (n = 4). Smoking, ingestion of alcohol, drugs and oral contraceptives were prohibited during 9 weeks of study. Diets were prepared by university food service. Food consumed was recorded and nutrient intakes were assessed. Cheese was consumed in 84 to 112 gram portions every day for two separate 14 day periods. All other dairy products were prohibited in the diet except 240 ml of two percent milk per day. When cheese was consumed, daily diets contained ca 400 kcal, 100 mg cholesterol, and 700 mg calcium more than diets consumed without cheese.

Individual body weights were stable and no significant changes occurred in any anthropometric measure over nine weeks. A trend of becoming more lean existed in the exercise group. However, there was no significant change in serum total cholesterol, lipids, calcium, or anthropometric measures during the study. These results seriously question the advisability of recommending restricted consumption of dairy products to lower serum cholesterol.
