A heart-healthy diet should prioritize foods rich in omega-3 fatty acids, fiber, and antioxidants. This includes whole grains, such as oats and quinoa, lean proteins like fish and poultry, and a variety of fruits and vegetables. Additionally, incorporating nuts, seeds, and healthy fats, like avocado and olive oil, can significantly reduce the risk of cardiovascular diseases by improving cholesterol levels and reducing inflammation. Minimizing processed foods, refined sugars, and saturated fats is equally important in supporting heart health.
