常喝汽水易导致暴力？

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.
