Histamine Tracker
Oat bran
Plain oat bran is low in histamine itself, but it's often found in products with added ingredients that raise the overall level.
Oat bran on its own is not a meaningful histamine source — oats are generally well-tolerated in the histamine intolerance community.
-
Plain vs. packaged — plain oat bran cooked at home sits comfortably at the lower end, but many packaged oat bran products include dried fruit, flavourings, or preservatives that can push the overall histamine load up considerably.
-
Freshness factor — like most cooked grains, oat bran is best eaten fresh; reheated or stored leftovers can accumulate more histamine over time.
Checking the ingredient list on packaged versions is worth the extra few seconds before buying.
