MIAMI SHORES, Fla. -- A whole new era in school lunches has begun as the man who invented the South Beach Diet implements a new nutrition plan that kicked off in a handful of Miami-Dade County elementary schools this year.

It was not yet 11 a.m. at the Partin Settlement Elementary School in Kissimmee, Fla., on a sunny day last October. But lunch service necessarily begins early when there are 838 children to feed, and the meal was already well under way. Danielle Hollar walked calmly amid the lunchroom chaos, holding a large, raw, uncut sweet potato in one hand and a tray filled with tiny cups of puréed sweet potatoes in the other. That Hollar does not get frazzled even among hundreds of jabbering children is one of the talents she brings to her job. That she is tall and blond and slim, and many of the students seem to have school-kid crushes on her, is another.

For years, Arthur Agatston says, experts offered conflicting advice about what constituted a healthy diet.

Diets that distinguish between "good carbs" and "bad carbs," are not an effective way of controlling blood sugar levels, a new study suggests.
