Tomato (canned)

High histamine

Canned tomatoes carry both the histamine-liberating properties of fresh tomatoes and extra histamine from the canning process.

Tomatoes are naturally histamine liberators, and the canning process adds another layer to consider.

  • Histamine formed during processing — histamine develops during the handling and processing stages before the can is sealed; once sterilized, the histamine is locked in rather than continuing to build, but the levels are typically higher than fresh tomatoes

  • Compared to fresh — fresh tomatoes are already considered high, but canned versions are typically a step above due to storage and added acids

If tomatoes are something you want to keep in your diet, freshly prepared tends to be the gentler choice.
