Thirty-two healthy, normolipemic male college students eating in a single dining hall participated in a study designed to ascertain the effect of changing milk consumption on nutrient intake and lipoprotein. The men drank no milk for 3 wk, then 1500 ml milk with 2% fat daily for 3 wk, their usual diet for 2 wk, no milk again for 3 wk, 1250 ml nonfat milk daily for 3 final wk. Similarly, 30 female college students consumed either 480 ml lowfat yogurt, then no yogurt for 4 wk each in a crossover design. Body weight and physical activity were not different among dietary treatments. Protein, energy, and calcium intake varied significantly with changes of milk consumption. Total dietary fat decreased significantly when no milk or nonfat milk was consumed, whereas dietary cholesterol was significantly lower only when nonfat milk was consumed. Yogurt supplementation significantly increased intake of calcium and carbohydrate. Although some serum lipid means differed significantly among some sampling points, there was no effect on total cholesterol, total triglycerides, high density lipoproteins cholesterol, or distribution of electrophoretic lipoprotein fractions that could be attributed to changing milk or yogurt consumption.
32名在同一个食堂就餐的健康、血脂正常的男大学生参与了一项旨在确定改变牛奶摄入量对营养摄入和脂蛋白影响的研究。这些男性连续3周不喝牛奶,然后连续3周每天饮用1500毫升含2%脂肪的牛奶,接着按照他们的日常饮食摄入2周,之后再次连续3周不喝牛奶,最后连续3周每天饮用1250毫升脱脂牛奶。同样,30名女大学生采用交叉设计,先摄入480毫升低脂酸奶,然后各有4周不摄入酸奶。不同饮食处理之间的体重和身体活动情况没有差异。蛋白质、能量和钙的摄入量会随着牛奶摄入量的变化而显著不同。不喝牛奶或饮用脱脂牛奶时,膳食总脂肪显著降低,而只有饮用脱脂牛奶时,膳食胆固醇才显著降低。补充酸奶显著增加了钙和碳水化合物的摄入量。尽管在某些采样点一些血清脂质平均值存在显著差异,但改变牛奶或酸奶的摄入量对总胆固醇、总甘油三酯、高密度脂蛋白胆固醇或电泳脂蛋白组分分布没有影响。
