Ratatouille
A dish built almost entirely from histamine-active vegetables — tomatoes and eggplant together make this a high-load meal for many sensitive people.
Ratatouille is a classic that, unfortunately, combines some of the most histamine-active vegetables together.
-
Tomatoes and eggplant — tomatoes are well-established histamine liberators; eggplant is commonly listed as a concern on sensitivity lists, though the evidence for its liberator status is less firmly established than for tomatoes; both are consistently flagged, and eating them together may compound the effect
-
Reheated leftovers — reheated portions tend to be higher in histamine than freshly made ones, so eating it fresh is generally the better option if you do try it
If you enjoy similar flavors, a simple herb-based dish skipping the tomato and eggplant may sit better.
