These nuts are rich in omega-3 fats and contain higher amounts of antioxidants than most other foods. Eating walnuts may improve brain health and prevent heart disease and cancer.
Walnuts are most often eaten on their own as a snack but can also be added to salads, pasta, breakfast cereals, soups, and baked goods.
They’re also used to make walnut oil — an expensive culinary oil frequently used in salad dressings.
