Tomatoes & histamine FAQ
Are Tomatoes high in histamine?
High in histamine and a histamine liberator — avoid. Tomatoes are a double problem: they naturally contain histamine and they also act as a histamine liberator, prompting your own cells to release more. Concentrated forms — tomato paste, sauce, and ketchup — are stronger still. They are one of the few vegetables that nearly every low-histamine guide flags, so cooking them down does not make them safe.
Can I eat Tomatoes on a low-histamine diet?
