Last month the British Medical Journal published a study on the highly anticipated purchasing data examining the impact of taxing sugar sweetened beverages (SSB) in Mexico (1). This study reported that the 10% tax on SSBs was associated with an overall 12% reduction in purchases and a 4% increase in purchases of untaxed beverages one year after implementation. In this blog we examine this latest study, how it fits in with existing evidence, and how these results might apply to improving the control of obesity and improving child oral health in New Zealand.
