Dietary changes that can lead to improved heart health include increasing the intake of fruits, vegetables, whole grains, and healthy fats while reducing saturated fats, trans fats, and processed sugars. Incorporating food rich in omega-3 fatty acids, such as fatty fish, can further support cardiovascular health. Maintaining a healthy weight and moderating sodium intake are also essential. Regularly consuming foods high in fiber can help lower cholesterol and improve arteries' health. Collectively, these dietary adjustments can lead to better heart function and reduced risk of heart disease.
