Histamine Tracker
Iceberg lettuce
One of the most histamine-friendly vegetables — fresh, mild, and well-tolerated by most people with histamine sensitivity.
Iceberg lettuce is low in histamine and doesn't appear to trigger histamine release or block the enzyme that breaks histamine down.
-
Freshness matters — like all leafy greens, histamine can build up once cut leaves start to wilt, so fresher is better
-
Compared to other lettuces — iceberg tends to be even more neutral than darker, more complex greens like romaine or mesclun
Keeping it crisp and fresh in the fridge helps it stay as gentle as possible.
