Walnuts

Walnuts are a leading source of plant-based omega-3 fatty acids, with a 28-gram serving providing 2.5 grams of alpha-linolenic acid (ALA), exceeding other tree nuts by at least 1 gram per serving. This makes them a notable food for cardiovascular well-being. A significant 20-year cohort study conducted by Harvard University indicated that individuals who consumed five or more servings of walnuts per week experienced a 14% lower risk of total cardiovascular disease and a 23% lower risk of fatal heart disease. Walnuts also offer a good source of antioxidants and beneficial plant compounds, contributing to overall health.
