Serving meals and snacks at school is fraught with politics and pitfalls. While the battle rages in school cafeterias over menu choices, beverage sales, vending foods, and outright bans on what students can buy or even bring to school, there is some good news. More school districts are reducing the number of fried foods, increasing the levels of fruits and vegetables, and paying attention to fat, calories, and the sugar content of the meals they serve. In 2009, the School Nutrition Association found that, nationwide, nearly every school district offers students fresh fruits and vegetables, whole grains, and salad bars or pre-packaged salads. Many parents believe that outright bans are not the correct way to fight obesity, and suggest that the push to legislate food in schools may do more harm in the end. In truth, tackling obesity is more complicated than creating lists of foods that "thou shalt not eat." No studies prove that children who eat more fruits and vegetables are thinner than classmates who eat only french fries and milkshakes. One study summarized in a 2009 article in the "International Journal of Behavioral Nutrition and Physical Activity" suggests that cutting out the fat in children's diets may not be the best strategy for fighting obesity. There are many paths toward building a better, more nutritious school lunch, and not all of them demand extra resources. However, the author stresses that the best school lunch will always be the one that can pass the kid taste test, the cost test, and the nutritional demands of the National School Lunch Program.
