“What you want,” says Kelly Brownell, director of Yale’s Rudd Center for Food Policy and Obesity, “is to reverse the fact that healthy food is too expensive and unhealthy food is too cheap, and the soda tax is a start. Unless food marketing changes, it’s hard to believe that anything else can work.”

The penny-per-ounce tax, favored by Dr. Brownell and others, would produce a significant increase in retail costs: the 12-pack of Coke on sale for $2.99 would go for $4.43 and a 75-cent can would rise to 87 cents. These increases, Dr. Brownell estimates, would reduce the annual per capita consumption of soda by more than 11 gallons, to 38.5 gallons. “And the revenue,” he says, “could be used to subsidize fruits and vegetables, fund obesity prevention programs for children and home economic classes in schools, and more.”
