Here in the US I buy Daisy full-fat sour cream (not sure of percentage). The ingredient list reads "grade A cultured cream" and that's it! Can't beat an ingredient list like that. But when I go to Canada in the summertime I never buy sour cream as the supermarket I go to (and about the only choice for a 30-40 minute radius) has no sour creams without ingredient lists as long as my arm! Yogurt was pretty nasty there ditto, but in the last years or two I've begun to find perhaps one single brand of "Balkan-style" yogurt which is pretty acceptable
