Which lifestyle factor can significantly contribute to atherosclerosis?

• A. Regular exercise
• B. Low-fat diet
• C. Cigarette smoking
• D. Hydration

Answer: (C)

Cigarette smoking is a significant lifestyle factor that contributes to atherosclerosis, which is the buildup of fatty deposits, cholesterol, and other substances in the arteries. Smoking damages the inner lining of blood vessels, leading to inflammation and making it easier for plaque to form. The harmful chemicals in cigarette smoke can accelerate the development of cardiovascular diseases by promoting the oxidation of low-density lipoprotein (LDL) cholesterol, further exacerbating the atherosclerotic process. Additionally, smoking increases blood pressure and heart rate, which can strain the cardiovascular system over time. Therefore, smoking is directly linked to an increased risk of developing atherosclerosis and associated cardiovascular diseases. In contrast, regular exercise and a low-fat diet are lifestyle factors that typically promote cardiovascular health and may help prevent atherosclerosis. Staying hydrated is essential for overall health but does not have a direct impact on the development of atherosclerosis like cigarette smoking does.
