Buttermilk
Buttermilk is fermented, and fermented dairy products are often reported as more problematic than fresh milk for histamine-sensitive people.
Unlike plain milk, buttermilk gets its tangy flavor from bacterial fermentation, and fermented dairy products tend to sit higher on the histamine concern list than fresh equivalents.
-
Fermentation — the bacterial cultures used to produce buttermilk change the composition of the milk; fermented dairy in general is more commonly reported as a trigger than fresh milk, though buttermilk's histamine content can vary depending on the cultures used
-
Compared to plain milk — fresh whole milk tends to be better tolerated since it hasn't gone through a fermentation step
If you need a substitute in baking, plain fresh milk may be worth experimenting with as a gentler alternative.
