Which practice directly contributes to protecting the immune system?

Making balanced dietary choices is essential for protecting the immune system because a well-rounded diet provides the necessary nutrients that support immune function. Nutrients such as vitamins C and D, zinc, and antioxidants found in fruits, vegetables, whole grains, and lean proteins play critical roles in the body's ability to fight infections and inflammation.

Balanced dietary choices help ensure a steady intake of these nutrients, which can enhance the production and activity of immune cells, improve response to pathogens, and support overall health. When the body receives adequate nutrition, it can maintain energy levels and effectively respond to stressors, contributing to a robust immune defense.

On the other hand, practices like overeating, eating junk food, or skipping meals can lead to nutrient deficiencies or excessive calorie intake, which may impair immune function and increase susceptibility to illnesses. Thus, making informed and balanced dietary choices stands out as a direct contributor to a strong immune system.
