Crackers (wheat)

Basic wheat crackers don't contain meaningful histamine, but the full ingredient list is what really matters here.

• Watch the extras — many crackers include vinegar, yeast extract, or aged cheese powder, all of which are widely listed as problematic for histamine-sensitive individuals and may add to overall histamine load

• Simpler is better — plain crackers with short ingredient lists — flour, oil, salt — tend to be easier to tolerate than flavored varieties

Checking the label before buying is a useful habit with packaged crackers.
