To enhance heart health through nutrition, focus on incorporating foods rich in omega-3 fatty acids, such as fish, nuts, and seeds. A diet high in fruits, vegetables, and whole grains can provide essential vitamins, minerals, and antioxidants that support cardiovascular function. Additionally, limit saturated fats and sugars, opting for healthier fats like olive oil. Maintaining a balanced intake can help regulate blood pressure and cholesterol, ultimately promoting overall heart health.
