Oat bran that contained 15.35% total dietary fiber and 5.57% soluble fiber and oat bran concentrate (37.14% total and 13.57% soluble fiber) were tested for their effect on blood lipid levels, using young rats as the test model. Compared with a diet free of soluble fiber, oat bran concentrate exerted a more pronounced serum cholesterol-lowering effect than oat bran fed at the same dietary level (50%). This effect was of a similar magnitude in both hypercholesterolemic and normocholesterolemic rats. Oat bran concentrate (but not oat bran) also increased the level of high-density lipoprotein cholesterol, but this effect was significant only in hypercholesterolemic rats. At the 50% diet level, oat bran concentrate also lowered serum triglyceride levels, but again only in hypercholesterolemic rats.
