Students, Your Lunch Tray is on Candid Camera!

San Antonio health officials are determined to improve eating habits in elementary schools. And with the help of object-recognition software, they're taking their fight to the cafeteria. 

Thanks to a Department of Agriculture grant, five local schools will participate in the program, which will measure children's nutritional choices and caloric intake. At lunchtime, cameras will photograph each student's tray, before and after they eat. 

A computer object-recognition program will analyze each item of food and its size, and then compare that information to a database of nutritional data. The program will compile the information in order to track the students' overall health habits and choices. 

The pilot program will run in poor, minority campuses, where obesity and diabetes are already an issue. Here's hoping this high-tech approach to nutrition will yield the results officials need to turn things around.
