It's the stoplight of the nutrition world. Schools in Charlottesville, Virginia are implementing a color-coded system designed to help kids quickly know if a food is a healthy choice or not. The system, which codes foods with red, yellow, or green colors, was originally implemented by the University of Virginia Medical Center. The system, called "Signals for Health" ranks the foods into the three color categories based on the food's calorie, fat, and sodium content.

I'm 100% behind any program that helps kids eat more healthfully. Hopefully Signals for Health will take away some of the guesswork, and help steer kids toward the green light choices.
