(PhysOrg.com) -- Taxing sugar-sweetened beverages a penny-per-ounce could reduce consumption and generate significant revenue, finds a study by the Rudd Center for Food Policy and Obesity at Yale University and the Bridging the Gap program at the University of Illinois at Chicago.
Researchers created a model to estimate the potential impact a tax on sugar-sweetened beverages would have on consumption and revenue, based on regional beverage consumption data, historic trends in beverage consumption, and recent estimates of how price affects sugar-sweetened beverage demand.
The Yale researchers projected that a national penny-per-ounce tax on sugar-sweetened beverages could generate revenue of $79 billion over five years. This tax could also reduce consumption of these beverages by 24%, which translates into a daily caloric reduction of up to 200 calories, if no other beverages or food are added into the diet as substitutes.
Co-authors Tatiana Andreyeva, Ph.D., Frank Chaloupka, Ph.D., and Kelly Brownell, Ph.D., note that public health may be substantially impacted if the revenue is invested in obesity prevention programs, especially in populations with particularly high sugar-sweetened beverage consumption, such as youth and low-income groups.
According to lead author Dr. Tatiana Andreyeva, the Rudd Centers director of economic initiatives, Such taxes could help the nation and many states address serious budget deficits, both by generating considerable revenue and potentially decreasing health care costs from declining sugar-sweetened beverage consumption.
While several states and cities have attempted to institute an excise tax on sugar-sweetened beverages, all have been unsuccessful so far.
