The days of trading turkey sandwiches for Twinkies at school might be ending.

A new law went into effect July 1 requiring public schools nationwide to adopt nutrition and exercise goals before the new academic year begins.

Many parents are happy with the new requirements, which can mean healthier school lunches, fewer sugary foods from vending machines and classroom celebrations, and more exercise and activity during the school day.

But others say the requirements are too broadly worded. They want the law to have more teeth.

And I'm sure still others think schools have no business policing the contents of kids' homemade lunches or prohibiting Susie from taking cupcakes to her class on her birthday. I happen to disagree. If schools have my child 30 or 35 hours a week, I want them to help instill good habits. There's a lot more to learn at school than math and reading...social skills, self-discipline, and, yes, healthy lifestyles.

One key point is the law does not give schools additional funding to roll out the new requirements, according to this article. Sort of like the No Child Left Behind Act, only for food, not testing.
