Dannon Activia yogurt has been super popular here for years. According to Dannon, they use a "unique proprietary culture" that they have named "Bifidus Regularis." I don't know how or if it is different from the probiotics in other yogurts, though. Does the plain really contain more "sugar" (which I'm assuming is lactose, not added sugar--here there is no added sugar) than other plain yogurts? I don't know what they are selling in the US, but here everyone eats the plain kind.
