Wheat flour
Wheat flour is generally low in histamine itself, but gluten may cause issues for some people sensitive to both gluten and histamine.
Wheat flour doesn't contain meaningful histamine, but it overlaps with a pattern some people notice.
-
Gluten sensitivity overlap — some people who react to histamine also find gluten-containing foods harder to tolerate, though the exact connection isn't fully understood
-
Processing matters — plain flour is less of a concern than fermented or aged wheat products like sourdough, where bacterial activity can raise histamine levels
Starting with small amounts and tracking your response can help you understand how wheat flour fits into your personal picture.
