The possible effect of diet on plasma lipids was investigated in a group of vegetarians. Seventy-three men and 43 women who had adhered to a vegetarian diet for an average of three years were studied in the fasting state and compared with a randomly selected group of controls matched for age and sex. Mean cholesterol levels in milligrams per deciliter for vegetarians and controls, respectively, were 126 and 184; low-density lipoprotein, 73 and 118; very-low-density lipoprotein, 11.8 and 17.2; high-density lipoproteins, 42 and 49; and mean triglyceride levels 59 and 86. Mean weight and subscapular skinfold thicknesses were 58 kg and 6 mm for vegetarians and 73 kg and 17 mm for controls. Similar differences in lipid levels were found between subgroups of 42 vegetarians and controls with identical mean weights. Multiple regression analyses showed that consumption of dairy foods and eggs, but not body weight, was associated with the lipoprotein and cholesterol findings.
在一组素食者中研究了饮食对血脂的可能影响。对73名男性和43名女性进行了研究，这些人平均坚持素食三年，处于空腹状态，并与一组随机选择的、年龄和性别相匹配的对照组进行比较。素食者和对照组每分升毫克的平均胆固醇水平分别为126和184；低密度脂蛋白分别为73和118；极低密度脂蛋白分别为11.8和17.2；高密度脂蛋白分别为42和49；平均甘油三酯水平分别为59和86。素食者的平均体重和肩胛下皮褶厚度分别为58千克和6毫米，对照组为73千克和17毫米。在平均体重相同的42名素食者和对照组亚组之间也发现了类似的血脂水平差异。多元回归分析表明，食用乳制品和蛋类与脂蛋白及胆固醇结果有关，而体重则无关。
