I usually bristle when public health bodies preach and tell us what we should and should not be putting inside our bodies. But nowadays, I welcome some of their interventions especially when it comes to trying to tackle the out-of-control obesity epidemic. The latest intervention comes from Public Health England which is urging parents to be stricter about the sweets, cakes and fizzy drinks they give their children. According to the PHE, the diet of the average child contains three times more sugar than is recommended. So the advice is to limit them to two snacks a day of no more than 100 calories each.
