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

Eating a balanced diet is recognized as a fundamental action that can prevent illness because it provides the body with the essential nutrients needed to function optimally. A balanced diet typically consists of a variety of foods that include adequate amounts of carbohydrates, proteins, fats, vitamins, and minerals. These nutrients play crucial roles in maintaining bodily functions, supporting the immune system, and reducing the risk of chronic diseases such as obesity, diabetes, and heart disease.

While engaging in artistic activities, studying environmental science, and conducting experiments can have their own benefits, they do not directly target the prevention of illness through nutrition. Engaging in artistic activities might foster mental well-being, studying environmental science could lead to insights about health implications of environmental factors, and conducting experiments may enhance scientific understanding, but none of them specifically contribute to the nutritional balance required for illness prevention in the same way that a balanced diet does.
