London, Sep 20 : There is a need to ban the sale of caffeinated energy drinks to children and young people to tackle obesity and mental health problems, says an expert.

Caffeine is probably the most commonly used psychoactive drug across the world as it increases activity and heightens attention and awareness.

But caffeine also increases anxiety, reduces sleep and is linked with behavioural problems in children, said Russell Viner, Professor from the UK's Royal College of Paediatrics and Child Health (RCPCH).

Recent studies have also showed that it may have concerning effects on the developing brain.

This is alarming because psychological distress can lead to risky behaviours like drug use and poorer academic attainment, Viner said.

"It's time to bring in laws to ban the sale of caffeinated energy drinks to children and young people to tackle the twin epidemics of obesity and mental health problems," he stated, in the new study published in the journal The BMJ.

The high sugar content in many of the energy drinks (as much as 27g of sugar per 250ml serving) "undoubtedly contributes to the overall calorie excess and resultant obesity epidemic among our children".

But perhaps most concerning are the effects on sleep, Viner said, because research has established a clear inverse association between caffeinated energy drinks and sleep duration.

Children and young people in high income countries consume more sugar and calories than required and are therefore unlikely to need additional energy.

This combined with regular caffeine consumption is causing concern as there is little evidence of the effect caffeine could potentially have on the developing body, Viner said.

Instead of binging on energy drinks, humans can get energy naturally from a "good diet, refreshing sleep, exercise and, most importantly, interaction with other people".

While government's consultation must drive a search for improved evidence, "there is now sufficient evidence to act to protect children", Viner noted.

New Delhi (PTI): Russian chess great Garry Kasparov hoped that his "little joke" on Indian politics does not pass for "advocacy or expertise" after his cheeky social media post on Congress MP Rahul Gandhi's love for the game went viral.

Within hours of asking Gandhi to "first win Rae Bareli before challenging for the top", the 61-year-old said it was just a joke and should be seen as one.

"I very much hope my little joke does not pass for advocacy or expertise in Indian politics! But as an 'all-seeing monster with 1000 eyes,' as I was once described, I cannot fail to see a politician dabbling in my beloved game!" the former world champion, who retired in 2005, wrote in response to a post by actor Ranvir Shorey.

Shorey's comment appeared to be a dig at Gandhi's recent assertion that he was the best chess player among all Indian politicians. Kasparov gave the same reply to a few other accounts which commented on his original post.

The Congress recently shared a video of Gandhi playing chess on his mobile phone while on the Lok Sabha election campaign trail. The MP from Wayanad named Kasparov as his favourite chess player and drew parallels between the game and politics.

A user on X made a cheeky comment on his page, which read "feel so relieved that @Kasparov63 and @vishy64theking retired early and didn't have to face the greatest chess genius of our times."

Kasparov, rather unusually, originally responded to that post.

"Traditional (sic) dictates that you should first win from Raebareli before challenging for the top," wrote the fierce critic of Russian President Vladimir Putin who is based in Croatia after fleeing his country.

Gandhi, while naming Kasparov as his favourite chess player, described him as a "non-linear thinker" in the Congress video.

"...once you get slightly better at it, the opponent's pieces actually operate almost like your own," he said, drawing comparison between chess and politics.

He filed his nomination from Rae Bareli in Uttar Pradesh on Friday and is also contesting from Wayanad.

A former world number one for a record 255 weeks, Kasparov became the youngest-ever undisputed world champion at the age of 22 in 1985 and is a political activist now.

The iconic player is a contemporary of Indian great Viswanathan Anand.

Recently, when 17-year-old D Gukesh bettered his record of becoming the youngest challenger to the world title by winning the Candidates Tournament in Toronto, Kasparov had put out a congratulatory post on X.

He described Gukesh as "the Indian earthquake in Toronto".
