Nickel is probably an essential element for humans, with several possible roles in maintenance and production of body cells.

Adequate amounts are probably obtained from most diets, provided that the gut is functioning properly.

There is some evidence that a few people may develop a skin sensitivity reaction to nickel. For these people, acid food cooked in stainless steel utensils and canned food may need to be avoided.
