Another study: Whole grains good for heart

August 28, 2009 A Harvard study followed more than 30,000 men for 18 years. Researchers found that those who ate the highest amounts of whole grains were 19 percent less likely to develop high blood pressure.

In addition, men who ate the most bran also reduced their risk of developing high blood pressure by 15 percent .

Whole grains include foods such as bran, barley, wild rice and oatmeal. These grains may help the heart by lowering blood sugar, improving insulin sensitivity and promoting a sense of fullness so people eat less.
