A strong immune system is your body’s best defense against illness—but no single food can prevent you from getting sick. Instead, a balanced diet rich in vitamins, minerals, and antioxidants plays a key role in supporting your immune health.

Why Nutrition Matters for Immunity
Your immune system relies on essential nutrients like:

- Antioxidants – protect cells from damage
Eating a variety of colorful, nutrient-dense foods ensures your body gets what it needs to stay strong and resilient.
