18 Aug 2017 --- The health agency Public Health England (PHE) has shifted its focus away from solely targeting sugar to cutting excess calorie consumption from all sources in its anti-obesity strategy for children in the UK. “A third of children leave primary school overweight or obese and an excess of calories – not just excess sugar consumption – is the root cause of this,” says Duncan Selbie, Chief Executive of PHE. “We will work with the food companies and retailers to tackle this as the next critical step in combating our childhood obesity problem.”
