What foods commonly cause food allergies?

It can be tricky to identify what food is causing your allergic reaction, especially if you're reacting to a spice. Such less obvious reactions will require a bit of detective work.

Answers to these questions can be revealing:

  • When did the reaction occur?
  • Does the reaction in question happen after eating a certain meal or food?
  • Was the food that caused the reaction fully cooked?
  • What else was eaten (including spices, beverages, condiments...)?
  • Did anyone who ate what you did experience the same symptoms?
