Histamine Tracker
Prune
Prunes are concentrated dried plums — drying intensifies their natural compounds and sulfite treatments are common in commercial versions.
Fresh plums are generally considered low in histamine, though they appear on some histamine liberator lists — turning them into prunes changes the equation further through concentration and processing.
-
Concentration from drying — removing water concentrates everything the plum contains, meaning whatever histamine or biogenic amines are present become more potent per serving
-
Sulfite treatments — many commercially produced prunes are treated with sulfites to extend shelf life, and sulfites are well-known triggers for sensitive individuals
Looking for unsulfured prunes and keeping serving sizes modest can help if you rely on them for digestive support.
