for more i am joined by margo wootan, director of nutrition policy at the center for science in the publicest. we invited several food and beverage companies, as well as their trade associations, to join us. but they declined our offer. margo wootan, how does the federal government, by what authority, do they reach out into all these thousands of school stricts and compel this kind of new standard? >>un, school foods say little different than other aspects of education. you know, often education is more regulated at the state and local level, but when it comes to school foods, it's for a long time been a federal program. most of the money comes from the federal government, from congress, and the u.s. department of agriculture. so they have nutrition standards as conditions for getting that funding. if you're going to take the $13 billion a year, you need to serve kids healthy food. so congress and u.s. da sets detailed nutrition standards for school meals and now they will have standards that compete with those school meals. >> suarez: will cafeterias and companies that make prepared foods
