Sugar-sweetened beverage taxes, typically referred to as soda taxes, purpose to offer monetary incentives to shoppers selecting more healthy drinks whereas additionally funding public well being packages.
The analysis crew has been learning the implementation of sugar-sweetened beverage taxes all through the U.S. and the brand new research analyzed information from Seattle, the place the tax was applied in 2018. The Seattle information was in contrast with information from Portland, Oregon, a metropolis of comparable dimension and demographics however with no sugar-sweetened beverage tax.
“Whereas we and others have printed numerous research on the short-term results of SSB taxes the place they’ve been applied within the U.S., these taxes are nonetheless comparatively new, and we’d like scientific information on longer-term impacts to grasp if the insurance policies have the potential to generate sustained public well being advantages,” stated research lead creator Lisa Powell, distinguished professor and director of well being coverage and administration within the UIC Faculty of Public Well being.
The research are the primary to comprehensively consider the tax’s long-term impression throughout all retailer sorts and throughout all drinks and sweets bought.

“Our research present that even after accounting for potential substitution behaviors, like cross-border procuring or collection of different gadgets with added sugars, these taxes have a big, sustained impression on decreasing quantity and grams of sugar bought from sugary drinks,” Powell stated. “This means that taxes might completely cut back the demand for sugary drinks and assist to decrease charges of well being harms which can be related to added sugars.”
