Egg salad
Egg whites are associated with histamine liberation in their raw state, though cooking reduces this effect — and egg salad often adds vinegar-based mayo on top.
Eggs themselves don't contain histamine, but raw egg whites have a well-documented association with histamine liberation — one that cooking significantly reduces.
-
Egg whites specifically — the white of the egg is the part associated with histamine liberation in its raw form; cooking is known to reduce this effect considerably, which means cooked egg salad may be less of a concern on this front than the HIGH rating alone suggests
-
Mayonnaise — most commercial mayo contains vinegar and sometimes mustard, both of which are commonly reported triggers, and this tends to be the more meaningful histamine concern in a typical egg salad
Homemade egg salad with fresh mayo and minimal acidic additions tends to be gentler than store-bought versions.
