AbstractThe aim of this work was to evaluate the effects of three dietary fibre- and polyphenol-rich materials obtained from grapes on serum cholesterol, lipoprotein and triglyceride concentrations as well as on body weight, fat and protein digestibility in adult Wistar rats fed on cholesterol-free and 10 g kg-1 cholesterol-added diets. Dietary fibre content of materials ranged from 540 to 590 g kg-1. Intake of grape products increased stool weight and the amount of fat and protein excreted in faeces, but did not affect negatively animal growth or protein efficiency of the diet in Wistar rats. Studied grape fractions lower serum total cholesterol and LDL cholesterol concentrations in hypercholesterolemic rats. These results could be taken into account in potential applications of these products as a food ingredient. (C) 2000 Society of Chemical Industry.
