Which of the following is a factor that contributes to good health?

• A. Watching TV all day
• B. Prolonged sitting
• C. Skipping meals
• D. Diet

Answer: (D)

Choosing a healthy diet means providing the body with a balanced mix of nutrients—carbohydrates, proteins, fats, vitamins, minerals, and fiber—from a variety of foods. This fuel supports energy for daily activities, helps maintain a healthy weight, supports immune function, and lowers the risk of chronic diseases like heart disease and diabetes. Among the options, diet is the factor that most directly contributes to good health because it supplies the essential building blocks your body needs to function well and stay resilient. The other options reflect behaviors that can harm health: spending long periods inactive, like watching TV or sitting, reduces overall physical activity; skipping meals can lead to low energy and poor nutrient intake. So, diet stands out as the positive contributor to good health.
