Regular consumption of blueberries or anthocyanins is associated with a reduced risk of cardiovascular disease, type 2 diabetes, and cognitive decline, and supports weight maintenance.

Include blueberries in your diet regularly. Observational data suggests that eating about one-third cup daily is associated with significant health benefits, including lower risks of heart disease and diabetes. You do not need to consume large quantities to see benefits; moderate, consistent intake is key.
