2. Identify common risk factors for atherosclerosis: These typically include high cholesterol levels, smoking, high blood pressure, diabetes, obesity, and a sedentary lifestyle.
3. Analyze each option provided in the problem: High cholesterol levels, smoking, and high blood pressure are all well-known risk factors for atherosclerosis.
4. Consider the role of regular physical exercise: Regular physical exercise is generally considered beneficial for cardiovascular health. It helps to lower blood pressure, improve cholesterol levels, and reduce the risk of atherosclerosis.
5. Conclude which option is not a risk factor: Based on the analysis, regular physical exercise is not a risk factor for atherosclerosis; in fact, it is a protective factor against it.
