近几年,营养学界提倡晚间喝牛奶,这样有助睡眠和补充钙质。然而,睡前喝牛奶,并非人人都适宜。这是因为,正常人在入睡后往往不再饮水,夜间的尿量自然就会减少,尿中各种有形物质增加,使尿液变浓。而牛奶中含钙较多,睡前喝牛奶,会导致钙质在尿液中的浓度短时间内突然增高。对于泌尿系统结石患者来说,其中的草酸钙结石、磷酸钙是加重结石病的危险因素。另外,牛奶虽是健康饮品,但也不能代替水来喝。健康人每天喝250毫升~500毫升牛奶,就可以满足身体所需了。如果过量摄入牛奶,会引起尿钙排出增多。如 In recent years, nutritionists advocate drinking milk in the evening, this will help sleep and calcium supplements.

The more calcium in milk, drink milk before going to bed, will lead to a sudden increase in the concentration of calcium in the urine in a short time. For patients with urolithiasis, the calcium oxalate stones and calcium phosphates are risk factors for aggravating stones. In addition, although milk is a healthy drink, but it can not drink instead of water. Healthy people drink 250 ml ~ 500 ml of milk a day, you can meet the body needs. If excessive intake of milk, can cause increased urinary calcium excretion. Such as
