Millions have been served to children across the nation in varying stages of life, and they are an integral part of the nutrition of growing children.Children who may not receive a warm, home-cooked dinner can receive one at school.Nutrition standards have been upgraded to include more fruits and vegetables, and meals must include whole grains. Calorie standards must be adhered to.There has been some complaining at some schools about the calorie count; 650 for grade schoolers, 750 for middle schoolers and 850 for high school children.Multiply each times three, and that is plenty of food for the day. Children are supposed to be hungry at supper time.
