摘要：

Water-insoluble fiber-rich fraction (WIFF) was isolated from the pomace of Averrhoa carambola, which is popular in Asia. The effects of WIFF-added diet on the lipid and cholesterol metabolism in hamsters were investigated and compared with those of cellulose-added and fiber-free diet as controls. Experimental results showed that the consumption of carambola WIFF decreased (P < 0.05) the concentrations of serum triacylglycerol, serum total cholesterol, and liver cholesterol, and increased (P < 0.05) the concentrations of fecal total lipids, fecal cholesterol, and fecal bile acids. The intake of WIFF also increased the fecal bulk and moisture. These pronounced cholesterol- and lipid-lowering effects of WIFF might be attributed to its ability to enhance the excretion of cholesterol and bile acids via feces. Our results suggested that carambola WIFF is used as a promising cholesterol-lowering ingredient in human diets or new formulations of fiber-rich functional foods. (C) 2004 Elsevier Inc.
