I get severe diarrhea from almost all dairy products and anything containing whey, cream, milk fat, & dried milk. The only dairy I can eat without having bowl issues is skim milk, American cheese, mozzarella cheese, skim ricotta cheese, and Lactaid 1% milk. I even react when I drink lactose free whole & 2% milk; and hard cheeses (which aren t supposed to have lactose). It seems that only dairy products that contain 1% or less milk fat are the only ones I can eat without spending time in the bathroom after ingesting them. Is this really lactose intolerance or is it something else?
