My hon. Friend makes a very good point, and I will come on to that in a bit more detail. The important element is that any approach we take must be evidence based. I absolutely agree with her that we need to look at all the evidence.
I stated that the proportion of those aged two to 10 who were obese had gone from 17% in 2005 to 13% in 2013. The evidence suggests that childhood obesity rose quickly in the mid-2000s and has slightly fallen ever since. That is an important fact for two reasons. First, it suggests that our education programmes in our schools and the Government-backed campaigns on obesity within the last decade have had a positive impact in halting the increase in childhood obesity. Secondly, it undermines the scaremongering that suggests that childhood obesity is rocketing year on year. It simply is not; the reality is much more complex.
As my hon. Friend the Member for Totnes as already mentioned, there is a growing clamour for a sugar tax on soft drinks to combat childhood obesity. She has called in a recent article for a 20% tax on sugary drinks as part of that overall solution. Her calls have been echoed by the BMA and other public health campaigners. I have huge respect for my hon. Friend, but I think that a sugar tax is completely the wrong answer. A sugar tax is illiberal and patronising—in my view, nanny statism at its worst.
Given how sugar tax campaigners argue, one might think that consumption of sugar in the UK is at a record high. It is not. Consumption of sugar per head in the UK is falling, from a high of more than 50 kg a year in the 1980s to less than 40 kg a year now. What is more, soft drink consumption in the UK is falling. The latest household food survey from the Department for Environment, Food and Rural Affairs shows that household soft drink consumption purchases have fallen by 5.2% since 2011 and by 19% for high-calorie soft drinks in the same period. Regular soft drink purchases are now at their lowest level since 1992.
