During a United Nations General Assembly summit on non-communicable diseases -- a discussion that included diet and eating habits -- New York City Mayor Michael Bloomberg said "governments at all levels must make healthy solutions the default social option."

Speaking on the government's role in diet and health last week, Bloomberg told the UN General Assembly, "There are powers only governments can exercise, policies only governments can mandate and enforce and results only governments can achieve. To halt the worldwide epidemic of non-communicable diseases, governments at all levels must make healthy solutions the default social option. That is ultimately government's highest duty."
