From The Associated Press: The first major nutritional overhaul of school meals in more than 15 years means most offerings, including pizza, will contain with less sodium and more whole grains, with a wider selection of fruits and vegetables on the side. First lady Michelle Obama, U.S. Agriculture Secretary Tom Vilsack and celebrity chief Rachael Ray announced the changes. Pizza won't disappear from lunch lines, but will be made with more healthful ingredients. The new rules aren't as aggressive as the Obama administration had hoped. Congress last year blocked the Agriculture Department from making some of the desired changes.
