Blueberry Skins Found to Lower Cholesterol Levels
March 30, 2007| |
A recent study affirms the benefits of blueberry skins in controlling cholesterol. Researchers at the US Department of Agriculture Agricultural Research Service (USDA-ARS) found that feeding hamsters a diet extremely high in cholesterol, but supplemented with freeze-dried skins of rabbiteye blueberries, lowered the plasma cholesterol level in blueberry-supplemented hamsters.
In addition, the researchers also found that hamsters eating the blueberry-enhanced food fared better than hamsters fed the high-cholesterol diet augmented with the lipid-lowering drug ciprofibrate. The results may be linked to constituents in blueberry skins that can activate a protein involved in the breakdown and import of fats, according to Agnes Rimando, a chemist working with ARS. Among these constituents are resveratrol and pterostilbene, which have been cited for their antioxidant properties.
