Yes. The sugar in milk comes from naturally occurring lactose, not added sugar. This is true if you are buying whole, low-fat or skim milk (also known as fat-free milk). In fact, milk is one of the simplest foods you can buy — just milk, vitamin A and vitamin D.
So, is there added sugar in milk?
No. Just like all white milk, there is no added sugar in skim milk. The sugar in milk comes from lactose and while fat levels vary, all milk (fat-free, low-fat, 2 percent or whole milk) has the same amount of natural lactose — about 12 grams in each 8-ounce glass.
