A strong immune system is essential to keep your body safe from harmful viruses, bacteria, and diseases. While lifestyle choices like sleep, exercise, and stress management play a significant role, nutrition is one of the most powerful ways to strengthen the immune system. In this article, we will explore a variety of foods that can boost your immune defenses and keep you feeling healthy year-round.
1. Citrus Fruits: A Vitamin C Powerhouse
Citrus fruits, including oranges, lemons, grapefruits, and limes, are famous for their high vitamin C content.

Consuming garlic regularly can help reduce the risk of infections and enhance your body’s defense mechanisms.
Benefits of Garlic:
- Supports the activity of white blood cells.
- Reduces the severity and duration of colds.
