Abstract
Cholesterol-lowering effects of ${\beta}-glucan-enriched$ barley fraction were investigated in rats fed 0.5% cholesterol and barley as a fiber source. Male rats of Sprague-Dawley strain were divided into six groups and fed different diets for 5 weeks: normal (cholesterol-free), control (cellulose 5%), fiber-free, and three groups containing ${\beta}-glucan-enriched$ barley fractions. Although plasma cholesterol and triglyceride levels were not significantly different among different diet groups, ${\beta}-glucan-enriched$ barley fraction-fed groups had higher HDL-cholesterol concentrations than the cellulose control group after 5 weeks of experiment. The fecal excretion of cholesterol and triglyceride was significantly increased by barley diets. Fecal concentrations of cholesterol and triglyceride in cellulose control group were 38.2 and 2.6 g/day, respectively, whereas those of barley-fed groups were $52.4{\sim}59.2$ and $6.8{\sim}9.5$ g/day, respectively, during the experimental period.
