One hundred fourteen male volunteers (mean age 44.6 years) consumed one whole egg daily in their customary diets for 3 months. Their final serum cholesterol (SCHOL) and triglycerides (STG) levels were compared with their initial levels on customary free choice diets and also with their levels after a 3-month elimination of dietary whole eggs. All subjects had previously confirmed normal serum lipid levels and no history of heart disease. Four-day food records were kept during both experimental dietary periods. A Latin square design allowed analysis for seasonal effects on lipid levels. No significant change in mean SCHOL on either diet was found; there was a seasonal effect on mean STG. Significant linear associations of fat intake and of energy intake were found. There was no significant association of dietary cholesterol intake with either SCHOL or STG.
114名男性志愿者（平均年龄44.6岁）在其日常饮食中每天食用一个全蛋，持续3个月。将他们最终的血清胆固醇（SCHOL）和甘油三酯（STG）水平与其在习惯的自由选择饮食时的初始水平进行比较，并与在3个月内消除饮食中的全蛋后的水平进行比较。所有受试者此前已确认血脂水平正常且无心脏病史。在两个实验饮食阶段都记录了4天的食物摄入情况。拉丁方设计允许分析季节对血脂水平的影响。两种饮食方式下的平均SCHOL均未发现显著变化；平均STG存在季节效应。发现脂肪摄入量和能量摄入量之间存在显著的线性关联。饮食胆固醇摄入量与SCHOL或STG均无显著关联。
