Using a healthy scaling index, 100 points being the best - school lunches scored just 52 points - based on what kids actually ate and packed lunches were slightly higher, at 58 points. Scores were lowest for vegetables, especially greens, followed by seafood, whole grains and plant proteins. While other protein foods and fruit were well represented, foods with empty calories took the top spot.
