Everyone is told to eat their fruit and vegetables, but if you have an allergy to these foods, that will cause more harm than good. Fruit and vegetable allergies, like any allergy, occur when your immune system identifies the proteins in fruits or vegetables as harmful. When you come into contact with these proteins, your immune system responds and releases histamines, which then cause your allergic symptoms.

Many fruit and vegetables have been reported to cause allergic reactions, from strawberries to onions. Fruit and vegetables can be hidden ingredients in many foods, this is why it’s important to read the label or ask about ingredients before buying or eating certain foods. Ingredients in packaged foods can change at any time without warning, so be sure to carefully check the ingredients every time.
