What major health issue can arise from zinc deficiency?

Zinc plays a crucial role in the immune system, serving as an essential trace element that supports various immune cell functions. A deficiency in zinc can lead to impaired immune responses, increasing susceptibility to infections and illnesses. The immune system relies on zinc for the development and activation of T-lymphocytes, the cells responsible for orchestrating much of the immune response.

Furthermore, zinc is involved in the regulation of cytokines, proteins that are important for cell signaling during immune responses. Without adequate zinc, the body may struggle to respond effectively to pathogens, leading to a higher risk of infections and a slower recovery. This highlights why impaired immune function is a significant health issue resulting from zinc deficiency.
