Effect of dietary egg on serum cholesterol and triglyceride of human males

Abstract

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.
