METABOLISM OF FOOD HISTAMINE
Foods are complex and consist of nutrients that require to be degraded from the moment they enter the oral cavity. Digestive organs carry out the digestion of food thanks to digestive enzymes that reach the intestinal tract through several digestive secretions (salivary, gastric, pancreatic, intestinal and biliary) obtaining the nutrients required for the proper functioning of the organism.
Histamine, which is present in every food (of animal and plant origin), should be metabolized in order to be eliminated by urine without problems. Note that exogenous histamine does not have a functional role within the organism, and for this reason, it is eliminated without using any property.
ROUTES OF HISTAMINE METABOLISM
There are two known main routes of histamine metabolism in living beings, where Histamine N-methyltransferase (HMT) and Diamine Oxidase (DAO) are implicated:
