Milk can grow taller because it contains calcium, so milk with high concentration naturally has higher calcium content. The main ingredient of milk is protein, so don't drink milk when you get up in the morning, because protein will be consumed in the form of providing energy at this time, which is a "waste" for protein; Drinking milk at night helps you sleep, but you can't sleep after drinking it, because the diet before going to bed will bring a burden to the stomach, and the next day may cause eye edema, so it is best to drink it half an hour before going to bed.
