A dietary habit that can improve heart health is adopting a balanced diet rich in whole foods, such as fruits, vegetables, whole grains, lean proteins, and healthy fats. Specifically, incorporating foods high in omega-3 fatty acids, like fish, flaxseed, and walnuts, can reduce inflammation and lower blood pressure. Reducing saturated fat, trans fats, and added sugars while increasing fiber intake can support optimal cholesterol levels. These dietary changes can lower the risk of cardiovascular disease and improve overall heart health.
