Hypocholesterolemic effect of buckwheat protein extract in rats fed cholesterol enriched diets

To investigate the effects of buckwheat protein on cholesterol metabolism, we prepared an enriched protein extract from buckwheat flour. The rats were fed a cholesterol-rich semipurified diet containing the buckwheat protein extract, soybean protein or casein as protein source for 3 wks. There was n...

Description
Summary:To investigate the effects of buckwheat protein on cholesterol metabolism, we prepared an enriched protein extract from buckwheat flour. The rats were fed a cholesterol-rich semipurified diet containing the buckwheat protein extract, soybean protein or casein as protein source for 3 wks. There was no significant difference in food consumption and growth rate among the rats fed three protein sources. Plasma cholesterol levels were decreased in the rats fed the buckwheat protein extract diet compared to the rats fed the soybean protein or casein diet. Concentrations of hepatic cholesterol were also significantly decreased in the rats fed the buckwheat protein extract diet as compared to the rats fed other protein diets. These results suggest that buckwheat protein is one of the dietary factors available for improvement of cholesterol metabolism.
