title: Influence of psyllium preparations on plasma and liver lipids of cholesterol-fed rats.
abstract: Rats were fed a semi purified diet containing 0.5% cholesterol and 10% fiber (cellulose, pectin, psyllium seed and defatted psyllium husk). One additional group of rats was fed cholesterol (0.5%) as part of a fiber-free diet and another was fed the fiber free diet without cholesterol. Cellulose had virtually no effect on serum or liver lipids. Pectin had a lipid lowering effect. Psyllium seed exerted an effect on total serum cholesterol equal to that of pectin but gave higher levels of HDL-cholesterol. The effects of psyllium seed on liver lipids were more pronounced than those of pectin. Defatted psyllium husk feeding virtually normalized liver size and serum triglyceride levels and produced lower serum total cholesterol levels and higher HDL-cholesterol than observed in normal controls. Defatted psyllium husk feeding also yielded liver lipid values which were in the normal range. Fecal wet and dry weights were significantly higher in rats fed either psyllium preparation.
