Mustard seeds
Mustard seeds are moderately flagged for histamine sensitivity, and prepared mustard — which often adds vinegar — raises the concern further.
Mustard seeds on their own are a moderate concern, but how they're prepared makes a big difference.
-
Processing adds risk — prepared mustard typically includes vinegar and sometimes wine, both of which are widely listed as problematic on histamine sensitivity lists, making the final product more concerning than the seeds alone
-
Whole seeds vs. ground — whole mustard seeds used in cooking may be tolerated differently than ground mustard or prepared mustard condiments, though individual responses vary
If mustard is a regular condiment for you, it may be worth considering the full ingredient list, not just the seeds.
