A little soy goes a long way when it comes to blood pressure control.

Adding 40 grams of soy protein to daily diets -- the equivalent of a couple servings of soy milk and a couple ounces of soy flour -- may help lower blood pressure in people who have mild hypertension or prehypertension, a recent study suggests. Edamame, soy burgers, and soy-based cold cuts are other great ways to get your daily soy.
