Zinc is a key component in over 300 enzymes utilized in the body, and the mineral is also an important structural component of many proteins, hormones, neuropeptides, and hormone receptors. Previous studies report that zinc deficiency can result in immune dysfunction. Emily Ho, from Oregon State University and colleagues showed that reducing zinc caused improper immune cell activation and dysregulation of a cytokine IL-6, a protein that affects inflammation in the cell. Zinc deficiency induced inflammatory response in part by eliciting aberrant immune cell activation. Our results suggested that abnormal zinc status could contribute to chronic inflammation. Healthy food high in zinc include seafood, beef or lamb (lean meat), spinach, pumpkin and squash seeds, nuts, beans, mushrooms. Some people may benefit from zinc supplementation, Depending on diet and zinc level.
