Cherry tomato

Tomatoes are a well-recognized histamine liberator — meaning they prompt the body to release more histamine from its own stores, on top of any direct content they may contain.

• Liberator effect — tomatoes are consistently listed among the more significant histamine-liberating foods, and the smaller, more concentrated cherry variety tends to have a lot of flavor compounds packed in

• Ripeness matters — the riper the tomato, the stronger the effect tends to be, so very ripe or sun-dried forms are typically more problematic than fresh and firm

Highly concentrated tomato products like paste or sun-dried tomatoes tend to have a stronger effect than fresh tomatoes, since water loss concentrates their compounds significantly.
