What Is Histamine Intolerance?
Histamine is indispensable for the human body since it fulfils vital functions. For example, it helps to regulate the function of the gut and to dilate blood vessels when irritation is present. It is both produced in the body and taken in with food in various quantities. An intolerance occurs when the enzyme diamine oxidase (DAO) is inhibited or deficient. It is responsible for the break down of histamine in the body, ensuring excess histamine is flushed – without it your body builds up an unhealthy amount of histamine, which can cause a range of unpleasant symptoms.
