Taxing soda to slow the obesity epidemic

Adding a penny per ounce tax to sugar-sweetened beverages could slow the growth of obesity in the U.S.—and could raise billions of dollars for obesity prevention and soda-cans-mediumother health programs, according to a new analysis by seven public health experts in The New England Journal of Medicine.(1)

Overweight-and obesity-related medical costs in the U.S. total an estimated $147 billion a year—nearly 10 percent of all health care spending—and sugary drinks are a major contributor to the nation’s obesity epidemic. (24)

A penny-per-ounce excise tax would likely spur consumers to cut their sugary drink calorie consumption, potentially by 8 to 10 percent—enough to promote weight loss and lower the risk of sugary drink-related chronic diseases—and could raise nearly $15 billion per year, the authors write. Levying an excise tax directly on beverage manufacturers—rather than a sales tax on consumers—would likely be the most efficient way to collect the tax and lead to the greatest effect on consumption because consumers would see this as a higher price. A tax on the sugar content of beverages would also give manufacturers an incentive to cut down the sugar content of drinks.
