Adding a little more yogurt to your diet might help reduce high blood pressure. Researchers at Tufts University followed more than 2-thousand people over 15 years. Those who included a moderate amount of yogurt in their diets cut their risk of hypertension by a third. This was not a lot of yogurt -- just about a 6-ounce cup every few days. Doctors warn against adding so much yogurt that it increases caloric intake. One note -- this study was partially funded by yogurt maker, the dannon company.
