A food allergy or food intolerance is a common ailment that affects millions of people. Anybody can experience adverse reaction after consuming a specific food due to allergy. Even exposure to a tiny amount of allergen is enough to trigger severe symptoms in your body. This is because your immune system misidentifies certain compounds in such food as being harmful. As a result, the immune system triggers an allergic response. One of the biggest misconceptions about food allergies is that only a non-vegetarian diet can trigger allergic reactions. However, scientific studies and clinical research suggests that vegetarian food allergies are emerging in number. People might be allergic to certain vegetables and fruits because of a unique genetic composition.
