Walnuts contain alpha-linolenic acid (ALA), a type of omega-3 fatty acid that is beneficial for heart health. Consuming walnuts may help lower cholesterol levels and reduce the risk of cardiovascular diseases.
Omega-3 fatty acids in walnuts, particularly DHA (docosahexaenoic acid), are essential for brain health. Regular consumption may support cognitive function and may have a positive impact on conditions like Alzheimer's disease.
Walnuts are rich in antioxidants, including polyphenols and vitamin E. Antioxidants help neutralize harmful free radicals in the body, reducing oxidative stress and inflammation.
Despite being calorie-dense, studies suggest that incorporating walnuts into a balanced diet may not lead to weight gain. The combination of healthy fats, protein, and fiber in walnuts may contribute to increased feelings of fullness, potentially aiding in weight management.
Some research suggests that including walnuts in the diet may help improve blood sugar control, making them a suitable choice for individuals with diabetes. The fiber, healthy fats, and antioxidants in walnuts may play a role in regulating blood sugar levels.
The anti-inflammatory properties of walnuts may help reduce inflammation in the body, contributing to the prevention of chronic diseases associated with inflammation.
Walnuts contain compounds with potential anti-cancer properties, such as polyphenols and phytosterols.
The healthy fats in walnuts may aid in the absorption of fat-soluble nutrients, such as vitamins A and D, and other important nutrients from the foods consumed with them.
