Boost Your Immunity: Best Foods to Enhance Your Immune System
1. Understanding the Immune System
1.1 The Role of the Immune System
The immune system is the body's defense mechanism against pathogens such as bacteria, viruses, and fungi. It comprises various cells, tissues, and organs working together to identify and neutralize threats. A strong immune system is essential for preventing infections and maintaining health.
1.2 Factors Influencing Immune Health
Several factors influence immune health, including genetics, lifestyle, and diet. While genetics play a role, lifestyle choices like regular exercise, adequate sleep, and a nutritious diet significantly impact immune function.
2. Top Immune-Boosting Foods
