There is a lot of focus on sugar-sweetened beverages (SSBs) internationally, due to their role in tooth decay, obesity and diabetes [1-3], their lack of beneficial nutrients, and potential acceptability as an intervention target [4]. Our just published study has shown that an intervention to reduce the size of all single serve SSBs would probably be cost-effective in NZ [5]. In this Blog we elaborate on the issues and consider this intervention in the context of other interventions for addressing NZ’s obesogenic environment.

From 1 April 2018, the UK is putting in place a type of sugary drinks tax – actually a “soft drinks industry levy”. This blog reviews how they are doing it, early signs of its success, and ponders its relevance for NZ.  We also take this opportunity to point out some problems with a recent NZIER Report on sugary drink taxes.

In this blog we consider recent literature (particularly reviews) on the effectiveness and cost-effectiveness of dietary counselling as a health intervention. Most studies suggest that dietary counselling is effective though the benefits are typically modest and short-term. The literature on cost-effectiveness is mixed, and there is substantial uncertainty about long-run cost-effectiveness given the typically short-term trials involved. Addressing the obesogenic environment will have potentially (much) larger gains, and due to substantial reductions in obesity-related disease it is likely to be cost-saving. However, governments, policy-makers and the public are often interested in counselling interventions, necessitating close attention to cost-effectiveness of these interventions relative to more structural changes to the environment.

The Government has an action plan to tackle childhood obesity, but it lacks a tax on sugary drinks – a strategy for which there is good evidence.  A new Treasury Report on soft drink tax price elasticities has just emerged. It has the look of a strategically published document that if and when – during election year – certain politicians need to defend non-action on taxing sugary drinks, they can point to this Report and obfuscate.  Indeed, this New Zealand Treasury Report has already been used for this purpose in Australia. We critique this Report in this blog, with a view to preventing its misrepresentation and to encourage a more informed discussion on taxing sugary drinks.

In this blog we look at such successes to date and consider what could be done to further reduce availability of these products which are both harming oral health and fuelling the obesity epidemic.
