Which of the following health behaviors is crucial for reducing the risk of coronary artery disease?

Engaging in regular physical activity is crucial for reducing the risk of coronary artery disease because it has numerous positive effects on cardiovascular health. Regular exercise helps to improve the efficiency of the heart and lungs, reduce weight, lower blood pressure, and improve cholesterol levels by increasing high-density lipoprotein (HDL) cholesterol while decreasing low-density lipoprotein (LDL) cholesterol levels. Physical activity also enhances insulin sensitivity, lowers inflammation, and can reduce stress, all of which contribute to a healthier cardiovascular system.

In contrast, maintaining a sedentary lifestyle, consuming high amounts of saturated fats, and increased alcohol consumption are behaviors associated with higher risks of developing coronary artery disease. A sedentary lifestyle can lead to obesity and increased cardiovascular risk factors, while a diet high in saturated fats is linked to elevated cholesterol levels and plaque buildup in the arteries. Higher levels of alcohol consumption can lead to hypertension and various metabolic issues, further heightening the risk for heart disease. Therefore, the choice of engaging in regular physical activity stands out as a critical behavior for promoting heart health and reducing coronary artery disease risk.
