A Mexican tax on sugar-sweetened beverages has cut soft-drink sales by 6 percent, according to a new report.
The data, taken from the National Income and Expenditure Surveys across the years before and after the tax, found the reductions were higher among lower-income households, residents living in urban areas, and households with children.
The study, published by the Journal of Nutrition, also found after the tax was implemented there was a 16 percent increase in low and middle-income households purchasing water.
In 2016 The New Zealand Government ruled out a sugar tax, but said it would keep a close watch for emerging evidence that it was effective overseas.
More than 70 percent of Mexico's population is either overweight or obese.
