Adherence
Excise taxes on sugar-sweetened beverages (SSBs) effectively reduce consumer purchases, with a 10% price increase leading to a 12% decline in purchases, particularly among lower-income populations.
Government policies that increase the price of sugary drinks through excise taxes have been shown to significantly reduce their purchase, especially among lower-income groups. This suggests that fiscal interventions are a viable tool for public health officials aiming to reduce sugar consumption and its associated health risks like obesity and diabetes.
An analysis of the Mexican tax in The BMJ suggests that it is working. The study showed that purchases of sugary drinks fell by 12% at the end of the first year after a 10% price rise, with greater declines among those who were less well off
Why this rating
