[[img]quote][/quote]Shunning water linked to high blood sugar(Reuters Health) -[/img]
[img][/img]
People who drink less than a couple of glasses of water each day may be more likely to develop abnormally high blood sugar, a new study suggests.

When someone's blood sugar levels are high, but not high enough to fit the definition of diabetes, doctors often consider that person to have "pre-diabetes" -- which puts them at risk of developing the disease itself.

In the new study, adults who drank only half a liter of water -- about two glasses -- or less each day were more likely to develop blood sugar levels in the pre-diabetes range, versus people who drank more water.

But whether simply drinking water will cut your risk of blood sugar problems is still up in the air.

The findings show a correlation between water intake and blood sugar, but do not prove cause-and-effect, said senior researcher Lise Bankir, of the French national research institute INSERM.

Still, it is plausible based on biology, Bankir told Reuters Health in an email.

A hormone called vasopressin is the potential missing link, according to the researchers.

Vasopressin -- also known as antidiuretic hormone -- helps regulate the body's water retention. When we are dehydrated, vasopressin levels go up, causing the kidneys to conserve water. But research suggests that higher vasopressin levels may also elevate blood sugar.

There are vasopressin receptors in the liver, the organ responsible for producing glucose (sugar) in the body, Bankir explained. And one study found that injecting healthy people with vasopressin caused a temporary spike in blood sugar."There are good arguments to suggest that there could be a real cause-and-effect relationship in the association we have found," Bankir said, "but this is not a proof."

The findings are based on 3,615 French adults who were between the ages of 30 and 65, and had normal blood sugar levels at the outset. About 19 percent said they drank less than half a liter (17 ounces) of water each day, while the rest drank up to a liter or more.

Over the next nine years, 565 study participants developed abnormally high blood sugar and 202 developed type 2 diabetes.

When the researchers looked at the participants' risk according to water intake, they found that people who drank at least 17 ounces of water per day were 28 percent less likely to develop high blood sugar than those who drank less than that amount.

There was no strong statistical link between water intake and risk of developing diabetes, however.

One obvious explanation for the connection with high blood sugar would be that people who drink little water may instead be reaching for sugary drinks -- which could lead to weight gain and impaired blood sugar control.

But Bankir and her colleagues accounted for sugary drinks and alcohol, as well as people's body weight at the start of the study, their reported exercise levels and certain other health factors. And the link between low water intake and high blood sugar persisted.

However, they could not account for everything, including generally healthy or less-healthy eating habits.

"Healthier behaviors correlating with higher water drinking could account for the observed association," the researchers write.

As for why there was no link between water intake and diabetes itself, Bankir said that the number of diabetes cases in the study was "too small to get a significant result." A larger study might have been able to detect a statistically significant link, she noted.

Further studies are needed to confirm the findings on blood sugar, according to Bankir.

But for now, she said, replacing sugary, high-calorie drinks with water would be a good idea for anyone. "In Western countries, the consumption of sugar is surely too high and contributes to obesity," Bankir said.

"Drinking less of them (sugary drinks) and more pure water can only be good in my view," she said.

    [LV.1]初来乍到

    我用网上翻译工具翻译一下,大家看个大概吧,如有错误,概不负责哦!

    文中这句话应该是不会错的。“水取代含糖,高热量的饮料,对任何人都将是一个好主意。”

    水与高血糖(路透社健康)
    人喝不到两杯水,每一天都可能更容易产生异常血糖升高,一项新的研究表明。

    当某人的血糖水平是很高的,但还没有高到足以适合糖尿病的定义,医生们通常认为人有“糖尿病前期”——这让他们在患这种疾病的风险本身。

    在这项新的研究中,只喝了一半的成年人一公升水的质量 -大约两杯或更少的每一天都更容易罹患血糖水平在糖尿病前期范围,与那些喝更多的水。

    但是是否只是饮用水的风险会减少血糖问题仍悬而未决。

    调查结果表明了取水和相关性的血糖,但却没有证实其因果、说为时尚早Bankir高级研究员表示,法国国民介入研究所。

    然而,他是似是而非的基于生物学、Bankir告诉路透社健康版在一个电子邮件。

    抗利尿激素称为潜在的缺失环节,根据研究人员指出。

    血管加压素 -也就是众所周知的抗利尿激素能帮助调节身体的积水。当我们脱水,抗利尿激素水平上升,导致肾脏节约用水。但是研究表明高血管加压素水平也可以提高血糖。

    有后叶加压素受体在肝脏、机关负责产生葡萄糖(糖)在身上,Bankir解释说。一项研究发现,在健康人群后叶加压素注入一个临时的剧增引起血糖。“有很好的证据表明有可能成为一个真正的因果关系,我们发现,协会”Bankir说,“但是这不是一个证明。”

    这项发现是基于3615年法国成年人年龄都在30和65,拥有正常的血糖水平,在一开始。大约19%的人说他们喝不到半公升(17盎司) 其余的则喝一升或更多。

    在接下来的9年,565个研究参与者开发异常高血糖和202开发的2型糖尿病。

    当研究人员根据水的摄入看着参与者的风险,他们发现的人喝的水,每天至少17盎司,28%不太可能发展比那些谁喝不到这一数额的高血糖。

    有没有强烈的水的摄入量和患糖尿病的风险之间的统计联系,然而。

    一个明显的解释是,与高血糖的人喝一点水,反而会深远的含糖饮料 - 这可能导致体重增加和血糖受损控制。

    但Bankir和她的同事占含糖饮料和酒精,以及人们在研究开始时的体重,他们报道的运动水平和其他一些健康的因素。低水的摄入量和高血糖之间的联系依然存在。

    然而,他们可能没有考虑一切,包括一般健康或不太健康的饮食习惯。

    “健康的行为,具有较高的饮水相关,可以解释所观察到的关联,”研究人员写道。

    至于为什么没有水的摄入量与糖尿病本身之间的联系,Bankir说,在研究糖尿病患者的数量是“太小,无法得到显著的结果。”一个更大的研究可能已经能够检测统计学意义的一个环节,她说。

    还需作进一步研究,以确认血糖的结果,根据Bankir。

    但现在,她说,水取代含糖,高热量的饮料,对任何人都将是一个好主意。 “在西方国家,食糖消费量肯定是过高,肥胖,Bankir说。”

    “他们少饮酒(含糖饮料)和更纯净水只能在我看来,”她说。
