Drinking milk at night is more favorable. Scientific research has found that the body's calcium metabolism will have a special law: the evening, especially at midnight, plasma calcium levels will appear a "trough", forcing the body to regulate the mechanism of transporting a part of the bone in the calcium to replenish. Thus, although the calcium in the blood is temporarily maintained, the calcium in the bones is reduced. Milk is rich in calcium, so drink a glass of milk before going to bed, can compensate for the body's night on the demand for calcium, in addition to promote sleep.

Often, people are accustomed to drinking milk in the morning, but from the full play of the nutritional role of milk, to get the maximum benefit, this is not the best time to ingest. The reason is that growth hormone, which has the greatest impact on human growth and development, plays a decisive role in the development of children and adolescents in particular. From the regular detection of plasma growth hormone concentration experiments found that 24 hours a day, in addition to 3-4 hours after the meal content is slightly higher, most of the time the concentration is lower, but after an hour of deep sleep, regardless of whether the children or adults, there will be a peak concentration: growth hormone content is the highest, this phenomenon is particularly obvious in the period of adolescence. At this time, the body's anabolic metabolism is strong, bones, muscles, internal organs grow rapidly, so the best time for children and adolescents to drink milk is at night before going to bed.

So, the morning milk to the night before going to bed to drink, in order to take full advantage of the nutritional value of milk, so that young children develop better, more healthy. For young people and middle-aged and elderly people have moisturized skin, the effect of beauty. Because the human skin cell division time is very special, it is only limited to the night, that is to say, the renewal of human cells to produce new world cells are in the human sleep.

So drink milk before going to bed that is to ensure that the skin enough nutrients, but also conducive to the skin's metabolism, making more new cells, so that the skin looks healthy, shiny, rich in elasticity, you can slow down the aging process, the youth permanent.
