This nutrition study was intended to contrast two different approaches to selecting a low-fat diet. One diet was a relatively typical American low-fat diet (n=61). The other incorporated considerably more vegetables, legumes, and whole grains (n=59), with modest amounts of butter, cheese and egg added so that both diets had the same amount of saturated fat and cholesterol. Participants were adults with moderately elevated cholesterol levels, but with no history of heart disease. After assigning the participants to either one group or the other and then providing them with all of their meals for four weeks, cholesterol levels and other heart disease risk factors were examined. The diet with more plant foods was found to be more effective than the "typical" diet at lowering levels of LDL-cholesterol, even though both had the same levels of fat and cholesterol.

这项营养学研究旨在对比两种不同的选择低脂饮食的方法。一种饮食是相对典型的美国低脂饮食（n=61）。 另一组包含更多的蔬菜，豆类和全谷物（n=59），添加适量的黄油，奶酪和鸡蛋，使两种饮食具有相同量的饱和脂肪和胆固醇。 参与者是胆固醇水平中度升高的成年人，但没有心脏病史。 在将参与者分配到一组或另一组后，然后为他们提供四周的所有膳食，检查胆固醇水平和其他心脏病风险因素。 研究发现，在降低LDL-胆固醇水平方面，含有更多植物性食物的饮食比“典型”饮食更有效，尽管两者的脂肪和胆固醇水平相同。
