A study released today by UCLA and the California Center for Public Health Advocacy called "A Patchwork of Progress: Changes in Overweight and Obesity Among California 5th, 7th, and 9th Graders, 2005-2010" found that while in some counties, including Los Angeles, the childhood obesity rate is showing some decline, there has been an increase in more than half the state's counties. Much of the proposed policy covers kids' access and exposure to unhealthy foods at school, in their neighborhoods, and through the media. Now for the longer answer.
