On average, primary school children in England have at least three sugary snacks a day, Public Health England (PHE) found. This means that the sugar they consume is three times more than the recommended maximum.
Children between the ages of 4 and 10 consume 51.2% of sugar from unhealthy snacks. PHE has launched a campaign, Change4Life, to encourage parents to look for healthier snacks of no more than 100 calories, and to limit them to two a day. The campaign advises parents to give their children a maximum of two snacks a day, with each containing no more than 100 calories. The campaign will also offer parents special suggestions on a range of healthier snacks—ones with 100 calories or fewer—at selected supermarkets, PHE said.
PHE said it had also improved its app so that it could mark the content of sugar, salt and fat in food and drinks. Dr Alison Tedstone told the BBC she hoped the campaign would help parents to choose healthier snacks for their children. “If you wander through a supermarket, you can see much more goods being sold as snacks than ever before,” she said, “It’s a common phenomenon that kids’ lunchboxes are full of snacks, leading to a lot of calories for lunch. Our research shows that parents usually appreciate a rule of thumb (经验法则). However, they are surprised to know how much sugar their children are consuming in snacks now.”
Justine Roberts, founder of Mumsnet, said, “The intake (摄入量) of sugar that kids are getting from snacks and sugary drinks alone is pretty astonishing, and it can often be difficult to distinguish which snacks are healthy and which are not. The rule of thumb from Change4Life can help parents make their decision correctly and wisely. ”
