20% tax on soda could reduce obesity
Introducing a tax on soda may be a good method for reducing obesity, according to new research from the U.K. The research adds to evidence linking the consumption of sugary drinks and weight gain.
In the study, published in the BMJ, researchers from the Universities of Oxford and Reading analyzed data from surveys of grocery purchases, drink consumption and the price of drinks, body mass index (BMI) and drink population.
Their findings showed that an approximate 20 percent sales tax on sugary drinks could be particularly effective in fighting weight gain among people between ages 16 and 29. This age group consumes the most sugar-sweetened drinks.
The scientists suggested that more countries should adopt this kind of tax and then measure the results. It is unclear, however, how many governments would be willing to impose such a tax to help researchers gain more evidence.
