Histamine Tracker
Longans
Fresh longans are low in histamine with no known triggering properties, similar to their close relative litchi.
Longans share a botanical family with litchis and have a similarly low-histamine profile in fresh form.
-
Fresh is gentle — Fresh longans don't contain meaningful histamine and aren't associated with histamine liberation, making them a calm fruit choice
-
Canned and dried versions — Longans are commonly sold canned in syrup or dried, both of which introduce the same concerns as other processed fruits — potential fermentation and concentration of compounds
Fresh longans when in season are typically the easiest option for people tracking histamine.
