Indeed. I completely agree with the hon. Gentleman, and I shall come on to that subject later. I am relieved to hear that he is not on a sugar high for the debate.
I want to set out not only the scale of the problem but its consequences. It has consequences for the whole lifetime of our children, in relation to their physical and emotional health. They also suffer the impact of bullying at school, as they are too often stigmatised in the classroom because of their weight. There is increasing evidence that obesity is a factor in causing many preventable cancers, and it also has an impact on conditions such as diabetes and heart disease. This has a cost not only to individuals but to wider society and to the NHS.
The Minister will know how essential it is that, as part of the five-year forward view, we tackle the issue of prevention. We cannot do that without tackling obesity, particularly among children, given the lifetime impact and consequences of the condition. She will know that 9p in every £1 we spend in the NHS is spent on diabetes. We estimate from the evidence that the Health Committee took during our hearings that the overall cost of obesity to the NHS is now £5.1 billion a year, and the wider costs to society have been estimated to be as high as £27 billion, although the estimates vary. We simply cannot afford to take no action.
Physical activity is of course extraordinarily important and I am confident that it will feature strongly in the Government’s strategy, but it is no good focusing solely on that. Physical activity is good for children, whatever their weight. Indeed, it is good for all of us, whatever our age. However, any strategy that assumes that we can tackle childhood obesity solely through physical activity will simply be ignoring the overwhelming evidence that most of the gain will be in reducing calories. That is not just about sugar, however. It is easy to be accused of demonising sugar. The fact is that children have more than three times the recommended amount of sugar in their diet, but that is perhaps the easiest aspect of the problem to tackle. The Minister will recognise the fact that we are talking about overall calories, which also include fats.
