Abstract

This study was conducted to determine the effect of a mixture of two water-soluble dietary fibers, psyllium husk and glucomannan, on serum lipids, fecal fat excretion and body fat. Twenty one female Sprague-Dawley rats were randomly assigned into three groups (control, pair-fed control and test group) and fed a high saturated fat (20% lard) diet (control diet) or a test diet (psyllium husk and glucomannan added to the control diet at the level of 0.9% and 0.68%, respectively) for 8 weeks. Pair-fed control rats were allowed to eat the amount of diet consumed by test group the preceding day. The body weight gain and food efficiency ratio of test group were significantly lower compared with these of control group. The mean values of body weight gain and food efficiency ratio were lower in test group than in pair-fed control group, but the difference was not significant. There were no differences in food intake. The dry weight and water content of feces and fecal fat excretion were markedly greater in test group than in control groups. Serum total cholesterol and triacylglycerol levels were significantly lower in test group than in two control groups.1'he rats of two control groups had higher body fat contents than that of test group. These results indicate that the combination of the two water-soluble dietary fibers, psyllium husk and glucomannan, can be used as a potent lipid-lowering agent in individuals consuming high saturated fat diet.
