Extract: The effect of Egyptian diet on serum lipid levels in both healthy, normal weight and obese premenopausal and postmenopausal women was studied. The lean normal weight controls consumed a balanced isocaloric diet. Subgroups with different degrees of obesity consumed different amounts of hypercaloric diet consisting of a high essentially complex carbohydrate, low animal/plant protein ratio, moderate fat and fiber content. All subjects, including obese were normolipidemic. Nevertheless, slight non significant increases in triglyceride levels were observed with increasing obesity. Initially the total cholesterol levels were observed with increasing obesity. Initially the total cholesterol levels increased in the postmenopausal women, and was followed by a drop in the severely obese women. The converse was true of HDL-C which decreased in both overweight and obese premenopausal and postmenopausal women. There was a negative relation between triglycerides and HDL-C in both lean groups. In the obese subgroups the same relation was kept, but the two parameters were reversed, more so in the postmenopausal group. There was a high significant positive relation between total cholesterol and LDL-C in all obese women suggestive of increased lipogenesis due to hypercaloric intake. These results suggest that excess caloric intake including more complex carbohydrates and plant proteins had a normolipedemic effect in obese women, but lowered HDL-C levels and disturbed the relationship between triglycerides, total cholesterol, LDL-C and HDL-C especially after menopause.(author)
