- School study demonstrates importance of water in teenagers’ diets -

Coinciding with school dinners making the political agenda, a new study commissioned by water filter expert Brita reveals startling evidence to highlight the crucial role drinking water plays in improving teenagers’ concentration and behaviour. In just a week, Brita’s trial found that teenagers drinking only filtered water saw their concentration levels improve by up to nine times, and felt five times more alert than at the beginning of the study.

It found that their ability to recollect information also improved and their energy levels increased, leaving the teenagers feeling, on average, three times more energetic. However, this extra energy wasn’t expended in bad behaviour: feedback from teachers and the teenagers themselves pointed to a calmer classroom and greater participation in class activities.

The study was carried out on 45 pupils aged between eleven and fourteen, with half drinking only filtered water during school hours and half (the control group) drinking their usual soft and caffeinated drinks.

Findings included:
- Those drinking filtered water reported an increase of better concentration from 9% to 82% in the space of just a week, while those in the control group reported no increase at all.
- The control group reported a 50% drop in alertness by the end of the study whereas filtered water drinkers reported feeling on average five times more alert.
- While filtered water drinkers felt three times more energetic at the end of the study, only 5% of the control group reported increased energy levels.
- The number of filtered water drinkers feeling more calm than normal tripled by the end of the study whereas again, only 5% of the control group noted an improvement.

Psychologist and counsellor Philip Hodson who supports the study said: “The TV programme Jamie’s School Dinners highlighted the connection between young peoples’ behaviour and the food they consume. But until now, no-one has investigated thoroughly the equally vital relationship between behaviour and the liquids consumed. Brita’s study provides sufficient evidence for schools to consider the role of water hydration in the classroom, to promote concentration, enthusiasm and a better behaved class!”

David Banfield, managing director for Brita said: “Being a parent myself, I understand the need to provide a healthy diet for our families, but equally, the pressure on young people to buy into ‘cooler’ drinks that also contain high levels of sugar, additives and often caffeine. We know that some young people are put off drinking water because they don’t like the taste of tap water: Filtering the water can make it more appealing to young people, enabling them to increase water consumption and improve their wellbeing at such a crucial age.”
