Achieving healthier diets that are also sustainable is increasingly in the news. In this blog, I look at the case for reducing the amount of meat in hospital meals and gently remind our dietitian colleagues not to let their dietary advice get out of date.

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 . 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 . In this Blog we elaborate on the issues and consider this intervention in the context of other interventions for addressing NZ’s obesogenic environment.

We recently did a blog post on dietary salt and health, particularly with regard to a new large prospective study (the PURE Study). This facilitated useful feedback from others, along with input from colleagues in a journal club we ran. Based on these discussions, we now have stronger concerns about remaining reverse causation in the PURE Study (and persisting concerns regarding other aspects). Here we update some of our thinking and conclude that the totality of the available evidence is sufficient for health authorities to continue taking a range of evidence-based actions to reduce the hazard of high salt intakes. Again however we invite critical comment on our assessment and suggestions on where to from here.

A large prospective study on dietary salt and health has recently been reported in the New England Journal of Medicine. While reinforcing extensive past work that a (very) high intake of salt is hazardous to health – an increased hazard was also found for low intakes of salt (i.e., a “J-shaped” or “U-shaped” relationship). This blog post considers this new study in more detail and suggests that we need a high-level international review to clarify the research and policy agenda from here. Our interpretation should be treated as preliminary on what may be an important study; therefore, we welcome and encourage comments on this blog post. [SEE MULTIPLE COMMENTS ON THIS BLOG BELOW.

Consumers have a right to have informative yet easy-to-use nutrition labelling, and effective labelling is one tool to help control the epidemics of obesity and diabetes. Everyone agrees that on its own, the current Nutrition Information Panel (NIP) used in NZ does not achieve the goal of facilitating healthier food choices. But suggestions around more consumer-friendly front-of-pack labels have been fiercely contested by industry and health stakeholders – until now, it seems. Is the new Health Star Rating label truly a win-win consensus, or might too much have been given away to reach a compromise?
