Building upon the sugar beverage tax in Mexico: a modelling study of tax alternatives to increase benefits.

INTRODUCTION: In 2014, Mexico implemented a one peso-per-litre tax to sugar-sweetened beverage (SSB). Even though this tax reduced household purchases and predicted population health gains, the magnitude is lower compared with taxes implemented in other settings. In this study, we assessed what would happen if Mexico modified its existing tax to get higher benefits based on currently implemented taxes elsewhere. METHODS: For each tax scenario, we estimated net benefits as the difference between healthcare savings and lost jobs. We created hypothetical scenarios in which the current tax doubled or would be modified based on existing tax designs around the world including specific taxes (sugar-density or volumetric) and ad-valorem taxes. RESULTS: We found that the largest benefits would correspond to a tax increase of 7.4 Mexican pesos (0.45 US dollars (USD)) per SSB litre, following the current tax in Bahrain (the highest tax rate option). This tax is predicted to yield net benefits equivalent to USD 24.7 billion after 10 years of the tax redesign. We also found that sugar-density taxes can result in larger net benefits since, in addition to reductions in consumption associated with responses to prices, they induce product reformulation. Middle-income households are the most benefited group because they reported the highest baseline prevalence of obesity and the largest price elasticity. CONCLUSION: Policymakers should consider pursuing a tax reform adding to the current tax, with significant increases in prices linked to a sugar-density strategy to reach a higher benefit.

How Could Taxes on Sugary Drinks and Foods Help Reduce the Burden Of Type 2 Diabetes?

PURPOSE OF REVIEW: Taxes on sugary drinks and foods have emerged as a key strategy to counteract the alarming levels of diabetes worldwide. Added sugar consumption from industrialized foods and beverages has been strongly linked to type 2 diabetes. This review provides a synthesis of evidence on how taxes on sugary products can influence the onset of type 2 diabetes, describing the importance of the different mechanisms through which the consumption of these products is reduced, leading to changes in weight and potentially a decrease in the incidence of type 2 diabetes. RECENT FINDINGS: Observational studies have shown significant reductions in purchases, energy intake, and body weight after the implementation of taxes on sugary drinks or foods. Simulation studies based on the association between energy intake and type 2 diabetes estimated the potential long-term health and economic effects, particularly in low- and middle-income countries, suggesting that the implementation of sugary food and beverage taxes may have a meaningful impact on reducing type 2 diabetes and complications. Public health response to diabetes requires multi-faceted approaches from health and non-health actors to drive healthier societies. Population-wide strategies, such as added sugar taxes, highlight the potential benefits of financial incentives to address behaviors and protective factors to significantly change an individual's health trajectory and reduce the onset of type 2 diabetes worldwide, both in terms of economy and public health.
