什么饮料最解渴?白水、茶照样汽水?都不是!苏格兰科学家的钻研发现,最补水的饮料含有乳糖、蛋白质和脂肪,你猜出来是哪栽饮料了吗?

When you're thirsty and in need of a drink, which beverages are best at keeping you hydrated?

倘若你感到口渴必要喝点东西,哪栽饮料最解渴呢?

Sure, you can always reach for a glass of water -- but plain H20 isn't the most hydrating beverage around, according to a study from Scotland's St. Andrews University that compared the hydration responses of several different drinks.

自然,你总是能够喝水的——但是按照苏格兰圣安德鲁斯大学的一项钻研,白水并非最解渴的饮料。这项钻研将几栽分别饮料的解渴奏效做了对照。

The researchers found that while water -- both still and sparkling --does a pretty good job of quickly hydrating the body, beverages with a little bit of sugar, fat or protein do an even better job of keeping us hydrated for longer.

钻研人员发现,尽管水(包括白水和苏打水)能够快捷给身体补水,但是,含有一点糖、脂肪或蛋白质的饮料补水最后更永远。

The reason has to do with how our bodies respond to beverages, according to Ronald Maughan, a professor at St. Andrews' School of Medicine and the study's author. One factor is the volume of a given drink: The more you drink, the faster the drink empties from your stomach and gets absorbed into the bloodstream, where it can dilute the body's fluids and hydrate you.

这项钻研的作者、圣安德鲁斯大学医学院教授罗纳尔德·莫恩说,因为和吾们的身体对饮料的逆答机制相关。一个因素是饮料的摄入量:你喝得越众,饮料从胃里排空并被血流摄取的速度越快,从而稀释体液,给你补水。

The other factor affecting how well a beverage hydrates relates to a drink's nutrient composition. For example, milk was found to be even more hydrating than plain water because it contains the sugar lactose, some protein and some fat, all of which help to slow the emptying of fluid from the stomach and keep hydration happening over a longer period of time.

另一个影响饮料补水奏效的因素和饮料的营养成分相关。例如,钻研人员发现,牛奶的补水奏效甚至比白水更佳,由于牛奶含有乳糖、蛋白质和脂肪,这些成分都有助于减缓液体从胃里排空的速度,拉长补水的奏效。

Milk also has sodium, which acts like a sponge and holds onto water in the body and results in less urine produced.

牛奶还含有钠,钠能够像海绵相通在身体里留住水分,并导致产生的尿液缩短。

The same can be said for oral rehydration solutions that are used to treat diarrhea. Those contain small amounts of sugar, as well as sodium and potassium, which can also help promote water retention in the body.

用来治疗腹泻的口服补水溶液也能够有同样的补水奏效。那些含有幼批糖、钠和钾的饮料也能够协助人体留住水分。

想要补水最后益 糖众不如糖少

But here's where it gets tricky: Beverages with more concentrated sugars, such as fruit juices or colas, are not necessarily as hydrating as their lower-sugar cousins. They may spend a little more time in the stomach and empty more slowly compared to plain water, but once these beverages enter the small intestine their high concentration of sugars gets diluted during a physiological process called osmosis. This process in effect "pulls" water from the body into the small intestine to dilute the sugars these beverages contain. And technically, anything inside the intestine is outside your body.

但是题目就在这边:糖浓度更高的饮料(比倘若汁或可笑)的补水最后就纷歧定有含糖量矮的饮料益了。和白水相比,这些饮料能够在胃里中断的时间更长一点,排空速度更慢,但一旦这些饮料进入幼肠,高浓度的糖就会在排泄作用(一栽心理过程)下得到稀释。这一过程会“抽出”人体的水分来稀释幼肠中的饮料糖分。厉格意义上来讲,幼肠内部的任何物质都会排出体表。

Juice and soda are not only less hydrating, but offer extra sugars and calories that won't fill us up as much as solid foods. If the choice is between soda and water for hydration, go with water every time. After all, our kidneys and liver depend on water to get rid of toxins in our bodies, and water also plays a key role in maintaining skin's elasticity and suppleness. It's the cheapest moisturizer you'll find.

果汁和汽水不光补水奏效更差,而且会挑供过众的糖分和炎量,财经新闻而且不会像固体食物相通令吾们产生饱腹感。倘若要在汽水和水当中选一个来解渴,你一定要选水。毕竟,吾们的肾和肝依赖水来倾轧身体里的毒素,而且水对于保持皮肤的弹性和软软也首到了关键作用。水是你能找到的最益处的润肤品。

While staying hydrated is important -- doing so keeps our joints lubricated, helps prevent infections, and carries nutrients to our cells -- in most situations people don't need to worry too much about how hydrating their beverages are.

尽管补水很惊险——能够保持关节润滑,协助防止感染,将营养输送到细胞——不过,在大众数情况下人们不必要太不安饮料的补水最后。

lubricate:vt. 使…润滑

"If you're thirsty, your body will tell you to drink more," Maughan said. But for athletes training seriously in warm conditions with high sweat losses, or for someone whose cognitive function may be negatively impacted by working long hours without beverage breaks, hydration becomes a critical issue.

莫恩说:“倘若你渴了,身体味通知你众喝一点。”不过,对于在高温条件下辛勤训练并大量排汗的行动员,或者对认知功能能够因长时间做事无暇喝水而受损的人而言,补水就变得很惊险。

啤酒和咖啡能够解渴吗?

Alcohol acts as a diuretic, which causes you to pass more urine, so when it comes to alcoholic beverages hydration will depend on a beverage's total volume. "Beer would result in less water loss than whiskey, because you are ingesting more fluid with beer," Maughan said. "Strong alcoholic drinks will dehydrate, dilute alcoholic drinks will not."

酒精有利尿作用,会让你排出更众尿液,所以酒精饮料的补水最后取决于摄入的酒量。莫恩说:“啤酒导致的水分流失比威士忌少,由于喝啤酒摄入的液体更众。烈酒会让人体脱水,矮度酒精饮料则不会。”

diuretic:n. 利尿剂

When it comes to coffee, how well your java hydrates you will depend on the amount of caffeine you consume. A regular coffee with about 80 milligrams of caffeine would be pretty much as hydrating as water, according to Maughan's research.

至于咖啡的补水最后则取决于你摄入的咖啡因总量。按照莫恩的钻研,一杯含有约80毫克咖啡因的清淡咖啡的补水最后和水差不众。

Consuming more than 300mg of caffeine, or about 2-4 cups of coffee, could cause you to lose excess fluid as the caffeine causes a mild, short-term diuretic effect. This is more likely to happen with someone who doesn't typically consume caffeine, and it could be offset by adding a tablespoon or two of milk to your cup of joe.

摄入超过300毫克的咖啡因,或两到四杯咖啡,会导致你失踪过众水分,由于咖啡因有温暖的短期利尿作用。不频繁喝咖啡的人更简单发生脱水,能够经历添入一两勺牛奶来抵消。

最补水的饮料排走榜

The research team at St. Andrews University tested 13 common beverages to see how they impact hydration. Here's what they found, ranked from most hydrating over a four-hour period to least.

圣安德鲁斯大学的钻研团队测试了13栽常见饮料的补水最后。下面是这13栽饮料在四个幼时内的补水最后排走榜(补水最后挨次递减):
