A 2011 University of Michigan study of more than a thousand middle school students found that those who regularly ate school lunches were 29 percent more likely to be obese than those who brought lunch from home. Of course, what a child eats for lunch is just one of many factors that determines whether he or she becomes overweight or obese. But many schools' dependence upon revenue from vending machines and brand-name fast-food over the past decade may be a tipping point.

The U.S. Department of Agriculture has decided to knock down the 20-year-old nutritional food pyramid and replace it with a simpler guide to healthy eating — a plate. Today the USDA will unveil how they think your dinner plate should look. But while the portion-divide plate might be a more digestible representation of a good diet, the question is will the message get through to people who really need to change their habits? Tony Geraci, former food service director for Baltimore City Schools and consultant for the Got Breakfast Foundation says that the USDA is addressing many health problems head on.

Today First Lady Michelle Obama will announce a campaign to fight childhood obesity. Part of the program will be to introduce healthier food in schools across the country. But will it work?

Local produce, farm-to-table dining, it's all the rage in foodie circles—and now, in the Baltimore public schools. For years, school systems have vowed to make lunch healthier and tastier. Luckily, Tony Geraci is used to a challenge. He has just finished his first year as head of food services for Baltimore City Public Schools, where he has dramatically changed the way Baltimore school kids eat. Joining him on The Takeaway are Michele Simpson and Rashad Epps, students at Baltimore City Public Schools.
