Grape extract shows cholesterol benefits

HDL—the “good” cholesterol—helps protect against heart and circulatory problems. In this study, 24 men and women who were overweight, pre-diabetic, or had elevated blood pressure, took a placebo or 350 mg of whole grape extract per day.

After six weeks, those in the whole grape extract group had much higher levels of HDL compared to placebo, and signs of oxidative stress and oxidized LDL decreased significantly for the whole grape group while increasing for placebo. Oxidized LDL is pro-inflammatory and plays a role in vascular disease.Whole grape extract contains concentrations of powerful antioxidants called proanthocyanidins, including catechin, epicatechin, and epicatechin-3-O-gallate. Doctors said the findings are important for people such as those in the study with greater chances of heart and circulatory problems, and that raising levels of HDL helps protect the heart.
