1 in 3 children in the UK will leave primary school obese, and whilst previous Sugar Smart campaigns from Change4Life had shone a light on the dangers of eating too much sugar, the problem remained and many parents found it difficult to know what was really in their food with confusing and inconsistent nutrition traffic light systems on food packaging.
