Abstract:

BACKGROUND: The aim of present study was to investigate the hypocholesterolaemic effects of oat proteins (OP) in hamsters fed with a hypercholesterolaemic diet. The hamsters were divided into five groups and fed with the experimental diets containing oat, OP, oatβ-glucan (OG), or OP+OG for 30 days.

RESULTS: OP and the OG significantly lowered the concentrations of plasma low-density lipoprotein-cholesterol and liver total cholesterol (TC), and increased the excretion of faecal bile acid and TC. Plasma and liver TC in the OP+OG group were significantly lower than those in the OP or OG groups. Both OP and OG increased the activity of liver cholesterol 7α-hydroxylase (CYP7A1), while its activity in the OP+OG group was strongly increased compared with the OP or OG groups.

CONCLUSION: These results indicated that dietary OP could improve hypercholesterolaemia, while dietary OP and OG together would have better hypocholesterolaemic effects.
