(CNSNews.com) – New York City Mayor Michael Bloomberg said the large soda ban set to go into effect this month at city restaurants, street vendors and movie theaters is how government tells the public what’s in their best interest. “We're not banning anything. It's called portion control,” Bloomberg said Sunday on CBS’s "Face the Nation." “It's a typical way that companies use to and governments use to explain to people what's in their interest and what isn't.”
