Taxes on sugar-sweetened beverages to curb future obesity and diabetes epidemics

Is it time for countries to consider taxing SSBs or raising existing taxes? This is the topic of the paper by Sanjay Basu and colleagues in this week's PLOS Medicine, in which they model the potential impact of a SSB tax for India. Assuming that sales of SSBs continue their non-linear increase, Basu and colleagues estimate that a 20% SSB tax may avert 4.2% of prevalent overweight and obesity, and reduce diabetes incidence by 2.5%, from 2014 to 2023.
