Skyr
Skyr is a fermented dairy product — the bacterial cultures used to make it can produce some histamine in the process.
Skyr is made by fermenting milk with live bacterial cultures, which is what gives it that thick, tangy quality — and also why histamine can be a factor.
-
Live cultures — the fermentation process involves bacteria that naturally produce histamine as a byproduct, similar to yogurt
-
Compared to yogurt — skyr and yogurt behave similarly in this regard; neither is heavily aged, but both involve active fermentation that produces some histamine
Some people with mild sensitivity find they tolerate small amounts of skyr fine, while others notice a reaction — it's worth paying attention to portion size.
