A strong immune system is essential for longevity and disease prevention. The food we eat plays a critical role in supporting immune function, reducing inflammation, and enhancing resilience against infections. This article explores the best immune-boosting foods and how to incorporate them into your diet for optimal health.

4. Garlic and Onions

• Contain allicin, a compound with antiviral, antibacterial, and anti-inflammatory properties.
