As politicians seek ways to combat the obesity epidemic here in the U.S., taxes and even bans on sodas have been floated in cities across the U.S. When former New York Mayor Michael Bloomberg first tried to tax and then limit the size of sodas in the Big Apple, howls of “the nanny state is here” roared across the country. Beverage industry trade groups screamed bloody murder over the cap on soda sizes that could be sold in NYC, and eventually New York State’s Court of Appeals ruled against the ban, saying the city’s health board lacked any such authority. Now an ex-mayor, Bloomberg has not given up. And a recent study on the effects of a similar policy in Berkeley, CA may give him even more ammunition as a campaign he bankrolled in Philadelphia was approved by its city council earlier this year.
