Public back ban on children's junk food advertising

And one in two support a tax on sugary drinks, which could help tackle the rising childhood obesity epidemic.

This new survey shows strong support for the Government to act in order to fight childhood obesity, with most (82 per cent) thinking it's a problem.

It also found that 69 per cent support reducing junk food advertising online and 66 per cent support cutting price promotions on junk food.

Almost six in 10 underestimated the proportion of overweight or obese adults in the UK according to the survey.

Being overweight and obese is a major cause of preventable illness and death in the UK, including cancer, type two diabetes, heart disease and stroke.

More than one in five children are overweight or obese when they enter primary school, and, alarmingly, this increases to one in three in year 6. This is why Cancer Research UK is calling on the Government to take action to protect children.

Alison Cox, director of cancer prevention at Cancer Research UK, said: "Junk food is everywhere. Children are bombarded by advertising tailored to tempt them with pretty colours and cartoons which all influence the food they prefer. At a time when junk food is cheap and packed with extra calories, we need stronger action to help prevent children from choosing these foods.

"We want the Government to ban junk food adverts on TV before the 9pm watershed, put a tax on sugary drinks and enforce targets for reducing the amount of fat and sugar in food. Reducing obesity rates could save the NHS billions of pounds. And, ultimately, we owe it to future generations to reduce preventable disease caused by being overweight and obese."

Dr Julie Sharp, head of health information at Cancer Research UK, said: "To give children the best chance of a healthy future, we need to make sure there are plenty of healthy options available to them. But this is difficult when they're exposed to lots of cheap junk food.

"Obese children are more likely to be obese as adults, which in turn increases their risk of developing cancer in later life, along with many other health problems. So it's important that young people are encouraged to eat healthily and keep active and that healthy choices are easy to make.

"Obesity is the biggest preventable cause of cancer after smoking and is linked to up to 10 different types including breast, bowel, and pancreatic cancer."
