There are several types of milk that can be used in a variety of ways. NONFAT, SKIM, SOY, OAT, spilt, and skimmed are all kinds of milk that can be used for different purposes. NONFAT milk is a type of milk that has had all of its fat removed, making it a low-fat option. SKIM milk is a type of milk that has had some of its fat removed, making it a lower-fat option than whole milk. SOY milk is a type of milk made from soybeans, and is often used as a dairy-free alternative to cow's milk. OAT milk is a type of milk made from oats, and is often used as a dairy-free alternative to cow's milk. Spilt milk is a type of milk that has been partially separated into cream and milk, and is often used in baking. Skimmed milk is a type of milk that has had some of its fat removed, making it a lower-fat option than whole milk.
