Milk (pasteurized)
lactose
Lactose itself is not a problem, but dairy products are often fermented.
Caution
May cause symptoms in more sensitive people. Track your own reaction.
Lactose is milk sugar and is not a histamine by itself. The problem is dairy products that are often fermented (yogurts, cheeses, sour milk) and therefore contain higher amounts of histamine or release histamine.
