Debate bubbles over sugary drink ban

New York City Mayor Michael Bloomberg's recent proposal to ban supersize soda and sugary drinks to fight obesity has triggered a debate that is largely between personal liberty and solid science.

Under Bloomberg's plan, any soda or sugary drink larger than 473 ml will be forbidden in local restaurants, theaters and stadiums. Diet coke, fruit juice and dairy-based drinks will not be affected, and neither will sales of sugary drinks in supermarkets and grocery stores, which are regulated by the state.

The proposal is expected to be submitted to the New York City Board of Health in the coming days. If passed, which is highly likely given that the board's members are appointed by Bloomberg, it could take effect as early as in March 2013. Businesses that don't comply could face a $200 fine.
