Center for Investigative Reporting article, "Open-campus policy eats away at school nutrition effort"
from the article:
"In recent years, lawmakers, regulators and school districts have tried to improve students’ health by curbing the sale of junk food and tightening nutritional standards for school food. But those efforts are undermined when students can leave campus to eat whatever they want, as they can at dozens of Bay Area high schools. Based on the experience in Oakland, closing campuses while offering free lunches can be an effective strategy."
