Sometimes easier said than done. Where I live, students only get 15 minutes for lunch. Which encourages unhealthy eating habits. Mind you, they only get 15 minutes of recess as well. While school lunch portions are okay, the calorie content calculations I did a few months ago brought me to the conclusion that the school assumes that none of the students eat dinner at home. The kids are being given their entire day's worth of food between the school-provided breakfast and lunch.
