On the December 1st edition of Your Call we’ll have a conversation with professor Marion Nestle about her new book "Soda Politics: Taking on Big Soda (and Winning)."

Soda is so tasty, but so not good for you. One can of coke has about 10 teaspoons of sugar, and too much sugar leads to obesity, diabetes and a host of other health problems.

Widespread diabetes compelled Mexico to pass a national tax on sugary soft drinks last year, but in the U.S. it has yet to happen. That may change tomorrow, if Berkeley or San Francisco passes respective measures that would levy taxes on distributors of sugar-sweetened beverages.
