Native to eastern North America, walnuts are grown worldwide, most commonly within Arizona and California. They are an excellent source of good fats, fiber, and protein. Walnuts can be enjoyed raw, roasted, salted, or unsalted. One cup of walnuts contains about 200 calories, 2 grams of fiber, and 5 grams of protein. Walnuts are high in omega-3 fatty acids, monounsaturated, and polyunsaturated fatty acids, making them great for your heart. These fats can lower bad cholesterol and reduce the risk of stroke, heart attack, and cardiovascular disease. Consuming walnuts can also help you burn more energy while at rest. Studies have found that diets rich in nuts provide higher rates of weight loss than those without nuts. Walnuts also contain the mineral copper, which is good for healthy bones. Eat walnuts by themselves, in granola, on salads, or with yogurt.
