Low-nickel diet scoring system for systemic nickel allergy

Dermatitis. 2013 Jul-Aug;24(4):190-5. doi: 10.1097/DER.0b013e3182937e81.


Background: Consumption of nickel in the diet leads to spongiotic dermatitis in a dose-related fashion in individuals who are allergic to nickel. Dietary modification to reduce nickel intake leads to resolution of this dermatitis.

Objective: This study aims to create an evidence-based, user-friendly diet to assist patients in reducing dietary nickel intake.

Methods: Food and Drug Administration data on the nickel content of foods were combined with serving size information to calculate the upper limit of nickel per serving for a variety of foods. Based on these calculations, a point system was created that allows patients to reduce their nickel intake below the typical threshold for elicitation of the spongiotic dermatitis.

Conclusions: A simplified point-based diet can help patients with dermatitis due to dietary nickel consumption.
