Young male rats fed an atherogenic diet containing cholesterol showed, at 2 weeks , a sharp increase in their serum cholesterol levels which gradually declined over the next 6 weeks. When sucrose in the diet (50%) was substituted, in entirety, with three wheat fractions (flour, germ, and bran), elevation in serum cholesterol levels was significantly less pronounced throughout, in germ- and bran- fed rats, and, to a lesser extent, in those fed patent flour. This occurred in bran-fed rats in spite of higher intake of cholesterol. Effect on serum triglyceride levels was inconsistent; still, some lowering of levels was observed in flour- and germ-fed rats. In rats fed a cholesterol-free diet, substitution of sucrose with wheat fractions did not lower serum cholesterol levels, and some reduction in triglyceride levels occurred only in flour-fed rats. Livers of cholesterol-fed rats showed marked infiltration of cholesterol and increase in weights; these changes, however, were much less pronounced in germ- and bran-fed rats. Liver triglycerides were little affected. In cholesterol-fed rats, substituting sucrose with bran lowered chylomicron and beta-lipoprotein fractions, and some reduction in beta- ad pre-beta-fractions was also observed in rats fed patent and whole wheat flours.
