Edamame
Soy-based foods, such as tofu, soy milk, and edamame, help fight heart disease when they replace fatty meats and cheeses, slashing saturated fat intake. Soy also contains heart-healthy polyunsaturated fats, a good amount of fiber, and some important vitamins. But stick with whole soy foods rather than processed foods, like veggie patties or chips. And, avoid taking soy supplements, which contain high and possibly dangerous amounts of isoflavones.
Oatmeal
Fiber-rich oats are even healthier than the FDA thought when it first stamped them with a heart disease-reducing seal 10 years ago. According to research, they can also cut your risk of type 2 diabetes. When Finnish researchers tracked 4,316 men and women over the course of 10 years, they found that people who ate the highest percentage of cereal fiber were 61 percent less likely to develop type 2 diabetes.
