Zinc

Zinc is an essential mineral, meaning the body needs it to function properly. It is naturally found in foods like meat, poultry, seafood, whole grains, and legumes. In fortified foods, it is often added in the form of zinc oxide or zinc sulfate.

Zinc is added to foods primarily as a nutrient to help consumers meet their daily recommended intake. It is commonly found in breakfast cereals, infant formulas, and nutritional supplements. It does not typically serve other functions like flavoring or preservation.

Zinc is recognized as safe and effective by the FDA when used as a nutrient in food. The National Academies of Sciences, Engineering, and Medicine have established a tolerable upper intake level (UL) for zinc. JECFA and EFSA have also evaluated zinc and its compounds. Adequate zinc intake is important for immune function and cell growth, and deficiencies can lead to health issues. However, excessive zinc intake can interfere with copper absorption and may cause gastrointestinal upset.
