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.
Walnuts are high in the healthy monounsaturated and polyunsaturated fats and omega-3 fatty acids. The combination of healthy fats, protein, and fiber in walnuts helps to increase satisfaction and fullness. This makes them more healthful as a snack, compared with chips, crackers, and other simple carbohydrate foods
