Green Tea & histamine FAQ
Is Green Tea high in histamine?
Low in histamine but a DAO blocker — best limited. Green tea (and concentrated matcha) is low in histamine on its own, but it slows the DAO enzyme, reducing your capacity to break histamine down from the rest of your diet. That hidden effect is why it appears on cautious lists. If you want a warm drink without the DAO impact, rooibos is a good swap.
Can I eat Green Tea on a low-histamine diet?
Green 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 Green Tea?
Lower-histamine swaps include Rooibos Tea. These are generally better tolerated than Green Tea on a low-histamine diet.
