Several dietary factors can improve heart health, including increasing the intake of omega-3 fatty acids, found in fatty fish, and incorporating more fruits and vegetables, which are rich in antioxidants. Reducing saturated and trans fats while increasing whole grains can contribute to lower cholesterol levels. Additionally, maintaining a balanced diet rich in potassium can help regulate blood pressure. Limiting sodium intake and choosing heart-healthy fats, such as those from nuts and avocados, further supports cardiovascular health. Overall, a holistic dietary approach is crucial for promoting heart health.
