Lactose is a form of sugar, but in terms of how our body manages it, it is all good sugar, so no problem with unflavored milk. The only "bad" sugar in milk is when we add flavoring (eg; chocolate milkshake).

There are quite a few "sugars" which are fructose free and milk (in fact virtually all unflavored dairy products) are fructose free.
