For unknown reasons, food allergies are on the rise in the UK. From rashes and sneezing to life threatening breathing difficulties, having an allergic reaction to food can be incredibly unpleasant. Food allergies are caused by the body mounting an immune response to a protein, or allergen, within a particular food that will not actually cause the body harm. The body releases histamine, which can make you feel unwell with various symptoms. Having food allergy testing may give you the confirmation you need to avoid particular foods, and also ensure you have the correct medication available in case of accidental ingestion.
