Dietary changes that can lead to improved heart health include increasing intake of fruits, vegetables, and whole grains while reducing saturated fats and trans fats. Emphasizing sources of omega-3 fatty acids, such as fatty fish and flaxseeds, can also benefit cardiovascular health. Additionally, limiting added sugars and refined carbs contributes to healthier blood pressure and cholesterol levels. Combining these nutritional strategies supports a heart-healthy lifestyle and reduces the risk of heart disease.
