Which nutrient is important for maintaining a healthy immune system?

Proteins play a crucial role in maintaining a healthy immune system because they are essential for the production of antibodies and other immune system components. Antibodies are proteins that specifically target and neutralize pathogens such as bacteria and viruses, helping to protect the body from infections. Additionally, proteins are involved in wound healing and the production of immune cells that defend against disease.

While carbohydrates provide energy and fats support cell structure and hormone production, neither is as directly involved in the immune response as proteins. Minerals, although important for various bodily functions, also serve supportive roles within the immune system rather than being fundamental building blocks like proteins.

Thus, proteins are specifically vital for immune function, making them critical in maintaining overall immune health.
