Delaware: A five-year sugar tax of 5 cents per ounce lowered consumption in five of Delaware’s sweetened beverage categories, according to a study from the University of Delaware and Stanford University.

The research, published in the journal JAMA Open, found a syruppy tax cut of 5.5 percent had the biggest impact on cola, 4.5 percent cut cola consumption, pints and other small-BOOSTs, and none of the other types of beverages.

“To date, no other state tax has been found to have such a large impact on beverage consumption,” said the study’s lead author, Benjamin S. Goldstein, PhD, an associate professor of epidemiology and public health in the UD School of Public Health.

The tax was assessed in the state’s beverage ID system, which raised $12 million for programs to promote healthy, affordable and sustainable beverage choices and prevent obesity. Currently $16 million is needed to close the ID system.

The tax was estimated to raise beverage taxes by 25 percent, which would lead to a downward fiscal impact of $2.4 million, the study estimated.

“Delaware showed producers that the excise tax reductions would reduce consumption of sugary drinks,” Andrews said. “And it showed producers that it would reduce consumption of flours, making it more perishable and therefore more saleable. With this tax, bars and restaurants in Delaware will have to make the transition to a one-size-fits-all approach, rather than a tax that each is presenting.”
