Nickel
Nickel is a trace element found in a variety of foods, though its nutritional function in the human body is not well understood.
Nickel is a trace element found in small amounts in many foods, especially plant-based ones. Although it’s present in the human body and may interact with enzymes, its precise function in human nutrition is not yet fully understood.
There is currently no established recommended dietary allowance (RDA) or upper intake level for nickel. It appears to play a structural or catalytic role in some microorganisms and animals, but its role in humans remains largely speculative.
Nickel is naturally present in foods like legumes, seeds, nuts, oats, and chocolate. While dietary intake is not a concern for most people, nickel can trigger allergic reactions in sensitive individuals — especially in skin contact or high-exposure environments.
