The hon. Gentleman may be reading from one of those notes that the Whips have been passing around, but I have not got around to mentioning the NHS yet. I will come to it.
I want to comment on the points made by the hon. Member for Vale of Clwyd. I agree that high-sugar diets are associated with a large number of serious conditions, including tooth decay, cardiovascular disease and type 2 diabetes. I will not repeat the figures, but I am grateful to him for giving the stats for five to nine-year-olds and for saying that such diets are the leading cause of hospital admissions for that age group. Of course, that imposes a considerable cost on our already overstretched NHS. He also rightly said that sugar is a leading cause of tooth decay for 15-year-olds, whose permanent teeth are being damaged. That is all preventable, as he said.
I think we are agreed that excessive sugar consumption is the main cause of tooth decay, so in principle I am in favour of a soft drinks levy. However, I am worried that it is an isolated policy and that it will fail to bring about the lasting change we hope for in the consumption habits of the public.
The hon. Gentleman gave the example of Mexico. If he looks carefully at what actually happened, however, he will see that, after an initial dip in sales of soft drinks, they subsequently rose and are now slightly higher than their pre-tax levels. The risk of such an isolated policy is that it may not have the long-lasting effect we seek. Indeed, it is debatable whether there is any robust evidence that an isolated levy on soft drinks will actually reduce the prevalence of any of the health conditions associated with high-sugar diets.
