Of course it is good. Milk contains a lot of animal protein, which can supplement calcium and is good for bone health and muscle growth. If economic conditions permit, it is no problem to drink milk as water, but it is a bit wasteful to drink milk on an empty stomach, because the protein in milk is not effectively used and directly consumed by the human body. In addition, if lactase is lacking in the body, the macromolecular lactose in milk will be difficult to digest. Too much milk makes it easy to have diarrhea, which is lactose intolerance. In this case, milk can't be drunk as water. Of course, you can also choose milk marked lactose-free. Another thing to note is that if you take medicine, it is best not to take it with milk, which will easily affect the curative effect. It is best to take the clothes with warm water.
