How much nickel is in a bowl if oatmeal?

The nickel content in a bowl of oatmeal is generally very low, typically around 0.1 to 0.2 micrograms per serving. Oatmeal is not a significant source of nickel, and the amount can vary based on the soil and water conditions where the oats were grown. For most people, dietary nickel is not a concern unless they have a specific sensitivity or allergy.
