Effect of Soluble Dietary Fibers on Blood Lipids in Rats

Abstract

Abstract: Three kinds of soluble dietary fibers including tomato soluble dietary fiber (TS), grape soluble dietary fiber (GS) and oat β-glucan (βG) were fed to SD rats with high fat diet to explore the effects of these soluble fibers on blood lipids. The results indicated that β G, TS and GS could significantly inhibit the increase of total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) in rat serum (P ＜ 0.05), compared with the model group. However, three kinds of soluble dietary fibers had no significant effect on body weight, body fat percentage, triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and atherogenic index (AI) of rats. Meanwhile, TS revealed stronger inhibition effect on the increase of TG than that of GS and βG. In contrast, βG exhibited stronger inhibition effect on the decrease of HDL-C.
