Walnuts are also a good source of:
- vitamin B6
They 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.
