According to the American Heart Association, which of the following is a guideline for cardiovascular health?

Maintaining cardiovascular health is crucial, and one of the most prominent guidelines outlined by the American Heart Association is the importance of not smoking. Smoking is a major risk factor for various cardiovascular diseases, as it damages the lining of blood vessels, increases blood pressure, and contributes to the buildup of fatty plaques in the arteries. By avoiding tobacco, individuals significantly reduce their risk of heart disease and promote overall heart health.

The other options either promote unhealthy behaviors or are not aligned with cardiovascular health guidelines. Regular physical inactivity, excessive alcohol consumption, and a high-sugar diet all have negative impacts on heart health, leading to conditions such as obesity, high blood pressure, and diabetes, which are linked to increased cardiovascular risk. Thus, refraining from smoking is a critical action for anyone looking to improve or maintain their cardiovascular health.
