Abstract

The effects of dietary taurine supplementation on plasma and hepatic lipid levels and phospholipid profiles were evaluated in rats fed a high- cholesterol or a cholesterol-free diet. Four groups of male rats were fed one of the following diets for 5 weeks: cholesterol-free diet (CFD); high cholesterol diet (HCD); high cholesterol, high taurine diet (HCHTD); or high taurine diet (HTD). Rats fed a HCHTD had significantly lower plasma levels of total cholesterol (32% reduction), LDL-cholesterol (37% reduction) and triglyceride (43% reduction) than rats fed a HCD alone. Plasma concentrations of total cholesterol, LDL-cholesterol and triglyceride were also significantly reduced in rats fed a HTD compared to rats fed a CFD. Taurine supplementation to the HCD significantly reduced hepatic cholesterol (50% decrease) and triglyceride (30% decrease) levels in rats. Taurine supplementation to the CFD also significantly reduced the hepatic triglyceride concentration (43% decrease) and elevated hepatic fatty acid levels (77% increase) compared to rats fed only a CFD. These results suggest that dietary taurine supplementation is both hypocholesterolemic and hypotriglyceridemic in rats whose body cholesterol status is high or normal.
