Base your diet around vegetables, fruits, legumes, whole grains, and small portions of nuts. Limit your intake of meat (especially processed meats like bacon and hot dogs). Try your best to eliminate refined carbohydrates (pasta, white rice), sweets, sweetened beverages, and added salt. Fish and shellfish can be a healthy choice as long as you vary the kinds you eat to minimize exposure to contaminants from pollution. Avoid trans fats and replace saturated fat with mono- and polyunsaturated fats. A Mediterranean-style diet, the DASH eating plan, and a balanced vegetarian diet are all good options.
