Effort to Improve schools meals will have difficult road

From The New York Times: With 20 percent of the nation’s children obese, the U.S. Department of Agriculture has proposed new standards for federally subsidized school meals that call for more balanced meals and, for the first time, a limit on calories. The current standard specifies only a minimum calorie count, which some schools meet by adding sweet foods. But this effort is up against an array of powerful forces, from economics to biology, all of which are playing out in Philadelphia, where the obesity rate is among the nation’s highest.
