Question: Why is good nutrition important to the immune system?


The immune system, like all organ systems, is constantly turning over its cells and protein components. It undergoes even more rapid turnover than most systems. The immune system must regenerate much of itself each day. It must be able to recognize antigenic substances and quickly synthesize many proteins, such as immunoglobulins, complement, and enzymes. It must rapidly grow lymphocytes, plasma cells, and neutrophils. More than most of the body’s systems, the immune system depends on adequate daily nutrition: amino acids for protein synthesis, fat and carbohydrates for energy production, vitamins and minerals for their specific roles in cellular growth and protein synthesis.
