Walnuts may also benefit brain function because they contain omega-3 fats, antioxidants, and other essential nutrients. Regular consumption has been associated with cognitive health, while their polyphenol antioxidants can help the body manage inflammation and oxidative stress. These qualities make walnuts a nutritious addition to a balanced diet.
Because walnuts provide protein, fiber, and healthy fats, they can help people feel full and may support appetite control and weight management when portions are kept reasonable. They also contain nutrients such as magnesium and naturally occurring melatonin. However, walnuts are calorie-dense, providing roughly 180–200 calories per ounce, so eating large quantities can quickly increase calorie intake.
Walnuts are also a common food allergen and can cause serious reactions in people with nut allergies. Eating too many may cause digestive discomfort for some people as well. Overall, walnuts can be a healthy part of the diet when consumed in moderate portions and according to individual tolerance.
