To promote heart health, individuals should avoid foods high in saturated fats and trans fats, as they can elevate LDL cholesterol levels. Processed snacks, fried foods, and sugary treats are typically culprits in this category. Reducing sodium intake is also essential, as high levels can contribute to increased blood pressure. Instead, focusing on whole foods such as fruits, vegetables, whole grains, lean proteins, and healthy fats can greatly support cardiovascular health.
