Why does the immune system depends on heaithy food?

The immune system relies on healthy food because nutrients from a balanced diet are crucial for the production and function of immune cells. Vitamins, minerals, and antioxidants found in fruits, vegetables, whole grains, and proteins support immune responses and help reduce inflammation. Deficiencies in these nutrients can impair the body's ability to fight infections and diseases. Thus, a nutritious diet is essential for maintaining overall immune health and resilience.
