美國研究發(fā)現(xiàn)飲水不足或導致肥胖

　　食品伙伴網(wǎng)訊   據(jù)外媒報道，《家庭醫(yī)學年報》（Annals of Family Medicine）刊登一項最新研究指出，飲水量不足可能導致肥胖。

　　美國密西根大學研究員分析9528名年齡介于18至64歲成年人的飲食習慣、喝水量，以及透過尿液濃度測量身體水化水準。

　　結果顯示，飲水量不足的人身體質量指數(shù)（BMI）較飲水充足的人高。

　　研究人員表示，雖然身體水化水準與體重之間的關聯(lián)不明顯，但維持水分充足應有助減輕體重，因為身體通常可以解釋饑餓和口渴的感覺。研究人員建議女性每天攝取2.7升，男性3.7升的水。

　　Researchers are learning whether a simple part of our diets might be linked to a healthier weight -- and it has nothing to do with carbs, fat or protein.

　　The potential secret weapon? Water.

　　People who are obese and have a higher body mass index （BMI） are more likely to be inadequately hydrated and vice versa, suggests new research from the University of Michigan published in Annals of Family Medicine.

　　“The link between hydration and weight is not clear. Our study further explains this relationship on a population level using an objective measure of hydration,” says lead author Tammy Chang, M.D., MPH, MS, an assistant professor in the Department of Family Medicine at the U-M Medical School.

　　Chang and colleagues looked at a nationally representative sample of 9,528 adults from the Centers for Disease Control and Prevention's National Health and Nutrition Examination Survey （NHANES）。 Roughly a third of the adults, who spanned ages 18 to 64, were inadequately hydrated.
