Dietary habits that can enhance cardiovascular health include consuming a diet rich in fruits and vegetables, whole grains, and healthy fats. Prioritizing foods high in omega-3 fatty acids, such as fatty fish, nuts, and seeds, can improve heart health by reducing inflammation and lowering triglyceride levels. Limiting saturated and trans fats, along with sodium and sugars, also supports cardiovascular wellbeing. Additionally, staying hydrated and maintaining a balanced diet helps in regulating blood pressure and promoting overall heart health, contributing to longevity.
