Systemic contact dermatitis to foods: nickel, BOP, and more

Highlights: Allergic contact dermatitis is a rash that occurs when an allergen touches the skin. Examples include: lotions, cosmetics, soaps, fragrances, metals, etc. The specific allergenic compound can often be identified through patch testing (physician puts a suspected compound on the skin, patches it and assesses the skin after a few days).  Many of these compounds are also found in food (e.g. nickel, balsm of peru). The article authors suggest a trial elimination diet, for patients that do not have satisfactory relief from eliminating topical exposure to the allergen. References are given for dietary guidelines.

Application to Dietetic Practice: The evidence for these elimination diets is based on case studies. To my knowledge, randomized clinical trials have not been done. However, being aware of this potential dietary trigger of contact dermatitis is important knowledge for dietitians working in food hypersensitivity.
