Yes some foods can cause a rash but it would be important to do a full history with you first. If the rash does not appear right away, then it is probably an intolerance. On the other hand if you have an allergy to house dust mite for example then I would check if your symptoms are worse in the morning. If it was related to hay fever-do you notice a flare up at certain times of the year? These are just two questions out of many that might help identify an airborne allergen rather than one related to food. Chemical allergies causing rashes are common and can be caused by toiletries, perfume, soap powder and household cleaners.Experimenting by changing to hypoallergenic products have proved very successful. Food sensitivities might be because of a histamine intolerance. Foods to avoid in that case would be pickled and canned foods, smoked meat, shellfish, beans and pulses, nuts, chocolate and alcohol.Some people have a salicylate allergy and that means no tea, coffee, black pepper, cherries, strawberries, tomatoes, cider wine and many more foods for a period of two weeks. If a food intolerance is suspected it is also important not to exclude foods for long periods because that might mean you become deficient in certain nutrients. And of course the rash could be caused by medication.As you can gather, working out what is causing a rash is very complicated. Please phone the pharmacy to find out more information on allergy screening.
