Walnuts are round, single-seeded stone fruits that grow from the walnut tree. They are a good source of healthful fats, protein, and fiber. They may enhance heart and bone health and help in weight management, among other benefits.
They are high in monounsaturated and polyunsaturated fats and omega-3 fatty acids. They are also a good source of protein. The possible health benefits of walnuts may include boosting the cardiovascular system and bone health, reducing the risk of gallbladder disease, and treating epilepsy.
