Which action most strongly reduces the risk of chronic diseases?

• A. Regular smoking
• B. Sedentary lifestyle
• C. No smoking
• D. High-sugar diet

Answer: (C)

Avoiding tobacco use lowers exposure to a powerful set of toxins that drive many chronic diseases. Not smoking removes a major, widespread risk factor for heart disease, stroke, several cancers, and lung disease, so it reduces overall disease risk more than any other single lifestyle change listed. When someone quits or never starts, the heart and blood vessels begin to recover, inflammation decreases, and cancer risk begins to drop over time. That makes not smoking the strongest action for long-term health. By contrast, continuing to smoke, leading a sedentary lifestyle, or consuming a high-sugar diet each contribute to risk in ways that compound over time, increasing the chances of cardiovascular disease, diabetes, cancer, and other chronic conditions. For CHWs, the focus is on supporting cessation, addressing withdrawal, providing resources, and promoting smoke-free environments to maximize these health benefits.
