Dr. Ornish: Reduce your intake of “bad carbs” (sugar, white flour, refined carbs) and increase your intake of good carbs (fruits, vegetables, whole grains, legumes, soy products in their natural forms) — as well as reduce your intake of “bad fats” (including trans fats and saturated fats) and increase your intake of “good fats” (e.g., omega-3 fatty acids).
Refined, highly processed carbohydrates can raise triglycerides, promote weight gain, and drive up blood sugar. On the other hand, starches that come from whole grains bring fiber, essential fatty acids, B vitamins, zinc, and protein, and other essential nutrients into our diets and provide an excellent source of energy. Beans, lentils, peas, starchy vegetables, and fruits are other healthy carbohydrate sources.
