Heart disease can be prevented by adopting a healthy lifestyle and managing risk factors. This includes maintaining a balanced diet rich in fruits, vegetables, whole grains, and lean proteins, engaging in regular physical activity, avoiding smoking and excessive alcohol consumption, and managing conditions like high blood pressure, high cholesterol, and diabetes. According to a study published in the Journal of the American College of Cardiology [https://www.jacc.org/doi/10.1016/j.jacc.2019.11.003], even modest lifestyle changes can significantly reduce the risk of developing heart disease. Regular check-ups and screenings can also help detect and address any potential issues early on.
