[转贴] 为孩子解渴?牛奶比清水更健康

Thirsty children shouldn't reach for water after P.E lessons... instead they should have a glass of milk, scientists say.
体育课后渴得不行的孩子们不该喝水……而是应该喝杯牛奶,科学家们如是说。

Researchers at McMaster's University said the white stuff was a more effective way at countering dehydration in active children than sports drinks or H20.
麦克马斯特大学的研究人员们称白色物质能比H2O更好的缓解儿童在运动后的脱水情况。

Study leader Brian Timmons, said: 'Children become dehydrated during exercise, and it's important they get enough fluids, particularly before going into a second round of a game.
研究的负责人Brian Timmons说:“孩子们在运动时很容易脱水,这时候补充水分至关重要,特别是当他们还要再重回运动场的时候。”

'Milk is better than either a sports drink or water because it is a source of high quality protein, carbohydrates, calcium and electrolytes.'
“无论是运动饮料还是清水都不如牛奶,因为它富含高品质的蛋白质、碳水化合物、钙和电解质。”

He added that milk replaces sodium lost in sweat and helps the body retain fluid better.
他还补充说牛奶可以补充流汗损失的盐分,并帮助身体更好的锁住水分。

The milk also provides protein, needed by children for muscle development and growth, not found in the other drinks.
牛奶还可以提供蛋白质,这是孩子们在肌肉发育和成长过程中不可或缺的,而其他饮料里都没有这一成分。

The study of children aged 8 to 10 involved exercising in a climate chamber, then receiving a drink and being measured for hydration.
这一研究中,若干名8至10岁儿童被要求在气候室中运动,然后分别饮用不同液体,并检查其缺水程度。

Assistant Professor Timmons, at the Michael G. DeGroote School of Medicine, said active children and adults usually don't drink enough to stay hydrated during exercise. This means they often have a 'hydration disadvantage' when they start their next period of exercise.
Michael G. DeGroote医学院的助理教授Timmons认为热爱运动的儿童或成人常常会忘记在运动中补充足够的水分。这意味着他们很可能在下一场运动中带着缺水状态下场。

He said that one per cent dehydration can cause up to a 15 per cent decrease in performance, with an increased heart rate, core temperature and less ability to keep going.
他说1%的缺水会导致15%表现不利,可以导致包括心跳加速、体温上升以及无法持续等问题。

More significant dehydration comes with an increased risk of heat-related illness such as heat stroke.
缺水的更大危害是会增加与温度有关的病症的风险,比如中暑。

However, the study was funded by Dairy Farmers of Canada, which may or may not be a moo-t point.
但这一研究的出资方是加拿大奶农协会,因此到底可信度如何就难说了。

可信度太低了,楼主你还发出来做什么
最后一句是关键句
牛奶确实健康,但是很多国内的牛奶不健康- -
就算牛奶比清水健康,但是不解渴啊。
这里指的是运动后,标题没写清楚
怎么到处都是软广告啊
还是喝清水放心
最后一句话让人怀疑这篇文章的可信度
最后一句是亮点。
身體每天補充水分最重要,然喝鮮奶也是補充蛋白質也
最后一句话亮了 而且牛奶根本不可能代替水
对啊,不是说消耗牛奶需要大量水分吗,有问题!
......最后一句让我不是很信任这篇文章的可信度
过多的蛋白质摄入,尤其是动物蛋白质摄入过多,都会对人体有害。一般情况下,人体不贮存蛋白质,所以必须将过多的蛋白质脱氨分解,氨则由尿排出体外。这一过程需要大量的水分,从而加重了肾脏的负荷,若肾脏功能本来不好,危险会更大。

过多的蛋白质摄入,也会造成含硫氨基酸摄入过多,这样会加速骨骼中钙的丢失,易产生骨质疏松。蛋白质的酸性代谢产物会增加肝、肾的负担,造成肝、肾肥大并容易疲劳。大量的蛋白质会导致机体脱水、脱钙、痛风。高蛋白对水和无机盐代谢不利,有可能引起泌尿系统结石和便秘。
