Black Tea & histamine FAQ
Is Black Tea high in histamine?
Low in histamine but blocks DAO — limit it. Black tea is not high in histamine itself, but it inhibits the DAO enzyme that breaks histamine down, so it can leave you less able to clear histamine from other foods. Green tea has the same effect. Herbal teas like rooibos do not block DAO and are a calmer everyday alternative.
Can I eat Black Tea on a low-histamine diet?
Black Tea is generally best avoided on a strict low-histamine diet because it can block the DAO enzyme that clears histamine. Tolerance is individual, so track your own response before reintroducing it.
What are lower-histamine alternatives to Black Tea?
Lower-histamine swaps include Rooibos Tea. These are generally better tolerated than Black Tea on a low-histamine diet.
