Non-dairy milk refers to imitation milk made from light vegetable oil. It has nothing to do with milk and does not have the nutrients of milk. It contains a large amount of trans fatty acids, which is very bad for human health. Fat is milk that has not been skimmed. Evaporated milk is similar to cream and has the same uses as cream. It is much thicker than milk and cannot replace milk, but you can dilute it and replace it
