Just one can of fizzy drink a day is linked to more aggressive behaviour by teenagers, claim researchers.
A new study found youngsters were significantly more likely to be violent and carry weapons if they regularly consumed fizzy soft drinks.
The study showed those having more than five cans of non-diet carbonated drinks a week were more likely to get involved in violent assaults.
The latest findings, reported online in the journal Injury Prevention, come from a survey of 1,878 teenagers aged 14 to 18 from 22 state schools in Boston.
They were asked how many cans of non-diet fizzy soft drinks they had consumed over the past week.
Up to four cans was considered "low", and five or more was classified as "high".
Just under one in three pupils fell into the "high" category, some drinking more than two or three cans a day.
Youngsters were asked if they had been violent towards their peers, a brother or sister, or a partner, and whether they had carried a gun or knife in the past year.
Overall, frequent soft drink consumption was associated with a 9 percent to 15 percent increased likelihood of engaging in aggressive behaviour.
The researchers, led by Dr Sara Solnick from the University of Vermont, said "There was a significant and strong association between soft drinks and violence. "

據(jù)英國《每日郵報》10月24日報道，研究人員稱，年輕人一天一罐汽水，易致言行暴力。

一項新研究發(fā)現(xiàn)，青少年如果定期飲用碳酸飲料，則更可能具有暴力傾向和攜帶武器。

該研究顯示， 那些在一周之內(nèi)飲用超過5罐含糖碳酸飲料的青少年更易參與暴力襲擊。

這些最新的發(fā)現(xiàn)源自一項對1878名年齡在14—18歲之間的青少年的調(diào)查。這些孩子均來自波士頓的22所公立學(xué)校。該項結(jié)果發(fā)表在《傷害預(yù)防》網(wǎng)站上。

研究調(diào)查了孩子們在上一周內(nèi)飲用的含糖碳酸飲料罐數(shù)。

飲用4罐和4罐以內(nèi)被認(rèn)為是“較低”，5罐或5罐以上則被定義為“較高”。
僅有不到三分之一的學(xué)生被劃分到“較高”一類，有的學(xué)生每天飲用超過2罐或3罐碳酸飲料。

青少年們被問及是否曾經(jīng)對他們的同齡人、兄弟姐妹或者同伴施加過暴力行為，以及是否在去年有過攜帶槍支或匕首的記錄。

總而言之，頻繁的飲用軟飲料與從事暴力行徑的可能性之間的聯(lián)系增加了9%—15%。

該研究的負(fù)責(zé)人——佛蒙特大學(xué)的薩拉索爾尼克博士說：“飲用軟飲料和暴力行為之間有著顯著而密切的聯(lián)系。”
