- Description The walnut is a type of tree nut that has a hard, tough shell. The inner meat looks sort of like a tiny brain and has a rich, sweet taste. The walnut is the most widely-consumed nut in the world and has been enjoyed for well over 8,000 years. The majority of commercial walnuts come from California and China. English walnuts and black walnuts are the two most common varieties. They’re eaten as-is after shelling or incorporated into delicious foods like bread, cakes, and even sauces for savory dishes. Health Benefits The walnuts are high in monounsaturated and polyunsaturated fats and omega-3 fatty acids. They are also a good source of protein. Nuts have a reputation for being a high-calorie and high-fat food. However, they are dense in nutrients and provide heart-healthy fats.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.
