Nutrition significantly impacts the immune system by providing the essential nutrients needed for immune cell function, development, and overall health. A well-balanced diet rich in vitamins, minerals, and antioxidants strengthens the body’s defenses against infections and diseases. Nutrients like vitamin C and zinc are crucial for enhancing the immune response. Additionally, healthy fats and proteins support the production of antibodies and cytokines. Conversely, poor nutrition can lead to deficiencies that weaken the immune system, making the body more susceptible to illness. Thus, proper nutrition is key to maintaining a robust immune response.
