Someone allergic to walnuts or pecans may not have an allergy to cashews or pistachios, even though close biological relatives often share related allergenic proteins.
Cases of chronic and solar dermatitides gradually decreased, which may be explained by reductions in the use of allergenic or photosensitive sulfur agents and organophosphates.
Other foods containing allergenic proteins include soy, wheat, fish, shellfish, fruits, vegetables, maize, spices, synthetic and natural colors, and chemical additives.
