California school officials say a growing number of students are eligible for free or reduced-price school meals. However, not all students can afford even the reduced prices, and some have been instructed by their parents not to buy food. In response, some schools are not taking students' ability to pay into consideration when serving nutritious school meals and after-school snacks. "If you're hungry, you can't learn," said Mary Driscoll, director of nutrition services in Marysville. "It's imperative we feed as many of these kids as we can."
