Taxes on sugar-sweetened drinks drive decline in consumption: Study

A brand new examine by researchers at UC Berkeley and elsewhere reveals that after excise taxes had been positioned on sugary drinks, purchases declined dramatically and steadily throughout 5 American cities. The findings have been printed in JAMA Well being Discussion board.

Though different research have evaluated the influence of beverage excise taxes—taxes on a per ounce foundation–in a single metropolis, this is likely one of the first that estimates the influence of native excise taxes on purchases and costs of sugar-sweetened drinks throughout a number of giant cities. The cities included Boulder, Philadelphia, Oakland, Seattle, and San Francisco, all of which applied taxes between January 1, 2017, and January 1, 2018.

Sugar-sweetened drinks—akin to sodas, fruit drinks, sports activities drinks, vitality drinks, and sweetened espresso drinks—are the main supply of added sugars within the American eating regimen, in accordance with the Facilities for Illness Management and Prevention. They’re related to severe destructive well being outcomes, together with kind 2 diabetes, weight problems, coronary heart illness, kidney illness, non-alcoholic liver illness, gum illness, tooth decay, and different circumstances.

Taxes on these kind of drinks are promoted as a key coverage to carry beverage corporations accountable for and cut back the well being harms related to their merchandise, however complete analyses of such taxes have been tough because of the absence of sufficiently giant samples of information and methodological limitations.

“Estimating a extra common, extra correct influence of native sugar-sweetened beverage taxes within the US supplies higher perception into the general effectiveness of those taxes,” mentioned examine lead creator, Scott Kaplan, who’s an economics professor at the USA Naval Academy. Kaplan acquired his Ph.D. from the UC Berkeley Division of Agricultural and Useful resource Economics in 2021. “This examine might higher inform the potential effectiveness of SSB taxes on the state or federal degree.”

This new examine builds on an earlier examine that regarded solely at information from town of Oakland.

The brand new examine discovered that retail costs of sugar-sweetened drinks elevated by 33.1% over the 2 years following tax implementation in every metropolis studied, and that there was a corresponding lower in purchases of 33% over the identical timeframe. The value improve and buy decreases appeared instantly after the taxes had been applied and continued to be sustained months later.

On the identical time, there was no proof that customers had been touring to bordering areas with out sweetened beverage taxes to make purchases there.

This examine’s findings recommend that “these taxes are fairly efficient by way of well being outcomes and societal cost-savings,” mentioned Kaplan. He hopes this will likely result in comparable coverage motion in different places throughout the nation, and on the state and nationwide ranges, as was executed with tobacco taxes.

A earlier examine co-authored by Dr. Kristine A. Madsen of UC Berkeley College of Public Well being confirmed that tax income from sugar-sweetened beverage (SSB) excise in seven cities had been used to assist initiatives to enhance group well being, develop human and group capital, and advance fairness.
