Black tea

Black tea contains compounds that are thought to reduce the activity of DAO — the enzyme your body uses to break down histamine in the gut.

• Possible DAO interaction — black tea contains polyphenols including tannins and theaflavins that have been associated with reduced DAO activity in some research, though the specific compounds responsible and the strength of this effect are not firmly established; the polyphenol profile of black tea differs from green or white tea due to oxidation, and the relative impact of each tea type isn't clearly understood

• Compared to other teas — lighter, less processed teas are generally considered a more comfortable option, though sensitivities vary between individuals

Having tea between meals rather than with a histamine-heavy meal may reduce the chance of a compounding effect.
