Adults in Mexico claim to be drinking fewer sugary drinks since the introduction of a sugar tax, a new poll has revealed.  

About half of respondents (52%) said they were consuming less soda in 2014 than last year, according to a national obesity survey released yesterday. Only 17% admitted to drinking more than three litres a week compared to 25% last year.

The obesity survey was carried out in August among 1,500 adults in Mexico.

The survey follows a tax of MXN1 (US$0.08) per litre of “sugar-sweetened” beverage implemented in January that targets growing rates of obesity in the country. Coca-Cola FEMSA blamed the tax for a decrease in its volumes for Mexico in first-half results.

Yesterday's survey, from public health advocates the Alliance for Health Food, revealed that a majority of the country's population (53%) support the sugar tax, up by 7% on last year. 

A separate study released earlier this year said that taxed beverage sales were down 10% in the first quarter of 2014 with non-taxed beverage sales up 7%, according to the alliance.
