Wine and histamine intolerance

Wine and histamine intolerance can be associated with an array of symptoms depending the degree of impairment of DAO (diamine oxidase) activity and the characteristics of the wine... For patients whose presentation suggests histamine intolerance aggravated by wine, consider assessing DAO activity and compensating with supplemented DAO for impaired production if indicated; the use of flavonoid compounds, notably quercitin; and a suggestion to seek wines higher in polyphenolic and flavonoid compounds.
