Healthy medical students were divided into two groups. One group was given double the normal fibre intake of their diet as a high-fibre-containing breakfast cereal; the other group (control) was given a breakfast cereal containing negligible amounts of dietary fibre. Otherwise the nutrient intake of the two groups was maintained constant. No differences in the serum-cholesterol, serum-triglyceride, serum-calcium levels were found between the two groups during or at the end of the study. The addition of a tolerable amount of dietary fibre to the diet does not affect serum-lipids.
健康的医学生被分为两组。一组食用高纤维早餐谷物，其膳食纤维摄入量是正常饮食的两倍；另一组（对照组）食用膳食纤维含量可忽略不计的早餐谷物。除此之外，两组的营养摄入量保持不变。在研究期间或研究结束时，两组的血清胆固醇、血清甘油三酯、血清钙水平均未发现差异。在饮食中添加适量的膳食纤维不会影响血脂。
