That milk can for water, because nearly 90% of the milk component is water. Water is the nutrient of primary importance to human life, one body of water is lost when more than 2%, the body's functions to run will be affected. The human body without water added, a few days can be life-threatening. So, when water supply is low, the milk can be used as a matter of course a source of water, a valuable supplement for the body of water.
However, when milk can not drink. Because of how much water we can drink much, but milk is not a. Reason is that milk also contains fat, protein, sugar, calcium, phosphorus and many other components, have limited their intake. If we need water every day come from milk, fat intake and other nutrients may be too much. Therefore, milk can not be unlimited as water. "High-nutrition" food can not be better.
That people can drink milk as the starting point is that the milk is highly nutritious beverage, but that since it is "high nutrition" should be better. Some of the "nutrition" a little misunderstanding, they read as nutritional content and quality of nutrients. High calcium content of milk, protein quality, but also contain more Chinese food supply is relatively insufficient vitamin B2 and vitamin A, so the "nutritious." But why say that this is the misunderstanding?
