由于一罐普通汽水中咖啡因的含量比一杯咖啡要低,大多数喝汽水的人大可不必为选可乐还是雪碧而发愁。但如果你体内的咖啡因含量已接近临界值,可能就要好好考虑清楚了。
The claim: Carbonated drinks weaken the bones.
误区三:碳酸饮料损害骨骼。
The reality: Research has zeroed in on the link between soda and bone density. A 2006 study found that women who drank three or more cans of Coca Cola a week had a significantly lower bone density. Researchers believe that the reason is phosphoric acid–found more often in dark sodas–which acidifies the blood, The Daily Beast reported. The body then “leaches some calcium out of your bones to neutralize the acid”, study author Katherine Tucker told the website.
事实:科学家们花大力气来研究汽水与骨密度之间的联系。一项2006年的研究表明,每周喝三罐以上可乐的女性骨密度明显较低。《每日野兽》网站有报道称,研究人员认为这是由于深色汽水中较为常见的磷酸成分使得血液酸化。该研究报告的作者凯瑟琳•塔克尔在接受采访时表示,人体骨骼将流失一部分钙质以中和这些酸性物质。
Others have suggested that it’s simply the carbonation that hurts bones, but the effect from a single soda is negligible, Popular Science reported.
《科技新时代》报道称,尽管一些人认为碳酸化作用会伤害到骨骼,但仅仅一瓶汽水的作用是微不足道的。
