Diet can lower blood pressure as much as taking a medication, from the February 2013 Harvard Men's Health Watch
Many people eat their way to high blood pressure (hypertension). It's also possible to eat your way out of it, according to the March 2013 Harvard Men's Health Watch.
The Dietary Approaches to Stop Hypertension (DASH) eating plan—low in animal fat and salt; abundant in blood-pressure-lowering nutrients—is scientifically proven to battle high blood pressure. It can reduce blood pressure by 10 points—about as much as adding a medication, says Dr. Deepak Bhatt, a professor of medicine at Harvard Medical School and chief of cardiology, VA Boston Healthcare System.
Here's the DASH plan in a nutshell: keep fat intake under 27% of total calories, eat many servings of fruits and vegetables, choose whole instead of processed grains, include low-fat or nonfat dairy products, and choose small portions of poultry, fish, and nuts as your primary source of protein rather than red meat.
