Walnuts are a type of nut that come from the walnut tree. They have a hard, brown shell that protects the soft, edible part inside. Walnuts are known for their rich, slightly bitter flavor and are often used in cooking and baking. They are a popular ingredient in salads, desserts, and even as a topping for various dishes. These nuts are not only tasty but also packed with nutrients. They are a great source of healthy fats, protein, and omega-3 fatty acids, which are beneficial for heart health. Eating walnuts can also provide antioxidants, making them a smart choice for a healthy diet.
