In Mexico, a 10% tax on sugar sweetened drinks has been associated with an overall 12% reduction in sales and a 4% increase in purchases of untaxed beverages one year after implementation, finds a study published by The BMJ this week.
The findings have important implications for policy discussions and decisions, say the researchers.
Mexico has some of the highest levels of diabetes, overweight, and obesity in the world, and reducing the consumption of sugar sweetened beverages has been an important target for obesity and diabetes prevention efforts.
From Jan 1. 2014, Mexico implemented an excise tax of 1 peso per litre on sugar sweetened beverages.
