Within the last few years, the First Lady has made many changes to American school lunches in order to attempt to make them "healthier". She had good intentions, but school lunches are not as healthy and nutritious as they are made out to be.
School lunches have been made so healthy, that they consist of a large number of empty and bad calories, and they are not nutritious. Also, the meals are too healthy, and children are not getting enough calories to keep them functioning.
The food is very generic, mainly consisting of very low quality frozen items that are warmed up. The quality was decreased in order to allow every child to be able to afford their lunch, but now the food is lacking any and all nutrition.
The school lunches need to have more nutritious and calorie rich items.
