Sugary Drinks Tax

Debate between John Glen and John McNally

Monday 30th November 2015 Westminster Hall

[John Mc Nally]

I could not agree more. That is one of the biggest problems. People drink lots of sugar, which gets them high quickly, but they then come down and go into a never-ending cycle of having to drink it again. It is an extremely worrying state of affairs for everybody, so I totally agree with the hon. Lady.

I believe that raising tax on sugary drinks would be an effective means of reducing childhood obesity. I thank all the MPs here, and I hope they all agree that Jamie Oliver should be applauded for setting up this petition and making use of his profile and that of the charity Sustain. I, for one, echo his concerns about the health and welfare of our future generations, and I share his belief that

“we can shift the dial on the epidemic of childhood obesity.”

I thank the right hon. Member for Leicester East (Keith Vaz), who is no longer in his place, for his diligent work in pursuing better public health awareness for the people of this country.

It is commonly known that sugar-sweetened drinks are associated with a higher risk of weight gain than similarly calorific solid food. Evidence indicates that there is a link between the habitual excess consumption of sugar, type 2 diabetes, and weight gain. A large study of European adults showed that there is a 22% increase in diabetes incidence associated with the habitual consumption of one daily serving of sugar-sweetened drinks. Sugar-sweetened drinks contribute a significant amount of sugar to children’s diets. A reduction in their consumption would, in my view, significantly lower the intake of sugar and therefore reduce obesity and the associated detrimental effects on personal health.

According to statistics released in 2014, 64% of adults in the UK are overweight or obese, which cannot be good for anybody. I am sure my hon. Friend the Member for Central Ayrshire (Dr Whitford) will talk about that fact later. International comparisons indicate that the UK has above-average levels of overweight and obese adults. The cost of our obese population is not just felt in the increased risk of a range of serious diseases, including type 2 diabetes, hypertension, heart disease and some cancers; there is also an economic cost. It is estimated that obesity costs the NHS up to £600 million in Scotland alone, and the McKinsey Global Institute estimates that the cost to the UK is equivalent to 3% of gross domestic product. The Scottish Government await the outcome of the Cochrane review on that issue.

Worryingly, for the majority of adults, obesity starts in childhood. Evidence shows that being obese in childhood increases the risk of becoming an obese adult. If we do not encourage adults and children to reduce their sugar intake, the economic costs and the cost to the NHS will continue to be a significant burden. Perhaps that is where a bit of libertarian paternalism is needed. As was said earlier, it is possible and legitimate to nudge people.

[John Glen]

Will the hon. Gentleman reflect on the fact that, sadly, a massive proportion of those who are obese are the poorest in our society? No Government of any party can ignore that fact. The poorest do not have a free choice when they buy sugary items.

[John Mc Nally]

The hon. Gentleman is right. Once again, it is the poorest who do not know how to make such choices. I hope to come on to that point later.

Although I welcome the proposal to increase tax on sugary drinks and agree with the rationale behind it, I am slightly cautious about it, simply because the body of evidence on this subject does not robustly demonstrate the effect it would have in isolation on rates of obesity and type 2 diabetes. I feel strongly that a raft of measures should be developed to reduce sugar intake and obesity. Taxation of this kind is an important tool in shifting the population’s dietary patterns. Educational messages alone simply will not achieve the reduction that we need, so fiscal and reformulation measures need to be introduced. We MPs can help to nudge that decision. We should improve the decision-making process to allow the choosers whom the hon. Gentleman mentioned to make better choices for their own welfare.

In conjunction with a sugar tax, we require legislation on the reformulation of foods to reduce overall calorie intake. If that is not possible, the industry should be compelled to reduce portion sizes—although not of Mars bars. We also need to introduce marketing restrictions on unhealthy foods to restrict the marketing of foods that are high in salt, sugar and fat to children. Restrictions should be applied most stringently to TV and online advertising, as evidence suggests that under-16s are strongly affected by advertising through those mediums.

We must improve our confused labelling system. We should continue to support a consistent front-of-pack labelling system and should extend caloric labelling, such as the traffic-light system, to all food and drink. Arguably, it is most crucial for the Government to invest more heavily in active travel by dedicating a national budget to walking and cycling; I am absolutely with the hon. Member for Warrington North on that.

The obesity epidemic is not going away. If anything, it will get worse for successive generations unless the Government take action. Implementing and evaluating a sugar tax as part of a childhood obesity strategy would be one step towards improving the health of our nation. I urge the Government to take heed of the petition and implement such a tax.

Finally, I holidayed in Cornwall this year, so I appreciate what the hon. Member for St Austell and Newquay (Steve Double) said about weight—such is the quality of the food in Cornwall.
