Rye flour
Plain rye flour is low in histamine, but it's frequently used in fermented breads that can be much more problematic.
Rye flour on its own isn't a significant histamine source — the concern is usually what it becomes.
-
Fermentation risk — rye flour is commonly used in sourdough-style breads, where long fermentation times cause histamine to accumulate significantly
-
Direct use is gentler — using rye flour in quick baked goods like flatbreads or pancakes sidesteps the fermentation issue entirely
If you're baking with rye flour at home without a long ferment, it's typically much easier to tolerate than store-bought rye bread.
