Diet, exercise, and tobacco use affect your chances of developing which of the following?

• A. All of the above
• B. CVD
• C. Cancer
• D. Type 2 diabetes

Answer: (A)

The main idea is that lifestyle choices shape risk for several major chronic diseases. Diet, exercise, and tobacco use collectively influence whether you develop cardiovascular disease, cancer, or type 2 diabetes. Diet affects heart disease risk through factors like blood pressure, cholesterol, and body weight, and it also impacts cancer risk via components such as fiber, fruits and vegetables, processed meats, and obesity-related processes; it influences diabetes risk by affecting blood sugar control and insulin sensitivity. Regular physical activity improves how the body uses insulin, helps control weight and blood pressure, and can lower cancer risk for some sites. Tobacco use is a strong risk factor for many cancers and for cardiovascular disease, with quitting reducing risk over time. Because these lifestyle factors touch all three conditions, the best answer is that all of the above are affected.
