It is a diagnostic test based on a blood test with which it is possible to identify if a case of migraine has a food origin

To do this, the level of the enzyme DAO, diamonooxidase, produced by our body and responsible for metabolizing a molecule called histamine in the intestine, is determined. This molecule is present in foods such as cheese, cold meats, fish, seafood, chocolate, vegetables such as eggplant or spinach, and in alcoholic beverages such as wine or cava.

A deficit of this enzyme causes histamine not to be eliminated correctly, so that this molecule accumulates in the blood plasma and can cause various reactions among which migraine stands out. It can also cause dermatological (atopic dermatitis), digestive (nausea, diarrhoea, constipation), muscular (contractures) or fatigue complications.
