What is an example of an action that can prevent illness?

Eating a balanced diet is an essential action that can prevent illness because it ensures that the body receives all the necessary nutrients needed for proper functioning. A balanced diet typically includes a variety of foods that provide carbohydrates, proteins, fats, vitamins, and minerals. These nutrients play crucial roles in maintaining health, supporting the immune system, and reducing the risk of chronic diseases such as heart disease, diabetes, and obesity. By consuming a wide range of foods, individuals can enhance their overall well-being and help their bodies resist infections and illnesses.

While engaging in artistic activities and studying environmental science or conducting experiments may have beneficial effects on mental health, education, or critical thinking skills, they do not directly contribute to physical health in the same way that a balanced diet does. Conversely, a balanced diet is a foundational measure that directly impacts health and helps prevent various ailments.
