Just one can of fizzy drink a day may make teenagers behave more aggressively

Some unusual humility (in red) below. High fizzy drink consumption may simply indicate high self-indulgence generally

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 US researchers are uncertain if the link is causal, but have not ruled this out.

It is possible that unknown factors causing aggression in youngsters also influence their dietary habits – which is why they opt for fizzy drinks – but previous research suggests poor nutrition may be a cause of antisocial behaviour.

The latest findings, reported online in the journal Injury Prevention (must credit), 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.

The scientists then investigated any potential links to violent behaviour. 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 per cent to 15 per cent increased likelihood of engaging in aggressive behaviour.

Violence and weapon-carrying was in any event common among the teenagers, who largely represented ethnic minorities from poor backgrounds. Of the group, 50 per cent were black or multi-racial, 33 per cent Hispanic, 9 per cent white and 8 per cent Asian.

However, rates of violent behaviour increased in a ‘dose response’ as students consumed more fizzy drinks, the researchers found.

Just over 23 per cent of teenagers drinking one or no cans a week had carried a gun or knife, rising to just under 43 per cent of those drinking 14 or more cans.

For the same increase in fizzy drink consumption, the proportion of those who had shown violence to a dating partner rose from 15 per cent to 27 per cent.

Rates of violence towards peers rose from 35 per cent to more than 58 per cent, and towards siblings from 25 per cent to more than 43 per cent.

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.

‘There may be a direct cause-and-effect relationship, perhaps due to the sugar or caffeine content of soft drinks, or there may be other factors, unaccounted for in our analyses, that cause both high soft drink consumption and aggression.’

Fish could cut risk of dementia as it boosts blood flow to the brain

Wow! They found that fish oil did NOT affect mental performance but still think it MAY be a good thing! Nothing can shake the Omega-3 religion

Eating fish may boost blood flow to the brain which could stave off dementia in later life, researchers have discovered.

The health benefits of a diet rich in omega-3, a fatty acid found in oily fish, have long been suspected, and the findings of two studies into its effects on young people suggest that it can improve reaction times in 18-35 year olds as well as reducing levels of mental fatigue after they perform tough tasks.

Although the results suggest that, contrary to popular belief, taking omega-3 or fish oil supplements may not have an impact on the mental performance of young adults, the researchers at Northumbria University say the increased blood flow to the brain it caused could be important for older people.

Lead researcher Dr Philippa Jackson said: ‘These findings could have implications for mental function later on in life. The evidence suggests that regularly eating oily fish may prevent cognitive decline and dementia, and increased blood flow to the brain may be a mechanism by which this occurs.

'If we can pinpoint both the behavioural and brain blood flow effects of this fatty acid in older healthy people, then the benefits for those with mental degenerative conditions associated with normal ageing could be that much greater.'

Researchers now plan to conduct a study on omega-3 use in people aged 50-70.

The study on soft drinks failed to determine whether the soft drinks consumed were Diet vs. Regular and/or Caffeine Free vs. Caffeinated and yet they then speculate that the behavior might have been caused by sugar or caffeine.

The whole point of their study is obviously to link soft drinks to anti-social behavior so it's no surprise that they found the result they were looking for.
