Not so fast food

As long as I can remember, children have been notoriously wasteful when dining in school cafeterias. Even those children who bring their own food often return home in the afternoon with their lunches half eaten. Not surprisingly, the food tossed out is often the healthier portion of the meal. Schools have tried a variety of strategies to curb this wastage, including using volunteer student monitors to police and encourage ecologically based recycling.

The authors of a recent study published on JAMA Network Open observed that when elementary and middle-school students were allowed a 20-minute seated lunch period they consumed more food and there was significantly less waste of fruits and vegetable compared with when the students’ lunch period was limited to 10 minutes. Interestingly, there was no difference in the beverage and entrée consumption when the lunch period was doubled.

The authors postulate that younger children may not have acquired the dexterity to feed themselves optimally in the shorter lunch period. I’m not sure I buy that argument. It may be simply that the children ate and drank their favorites first and needed a bit more time to allow their little guts to move things along. But, regardless of the explanation, the investigators’ observations deserve further study.

When I was in high school our lunch period was a full hour, which allowed me to make the half mile walk to home and back to eat a home-prepared meal. The noon hour was when school clubs and committees met and there was a full schedule of diversions to fill out the hour. I don’t recall the seated portion of the lunch period having any time restriction.

By the time my own children were in middle school, lunch periods lasted no longer than 20 minutes. I was not surprised to learn from this recent study that in some schools the seated lunch period has been shortened to 10 minutes. In some cases the truncated lunch periods are a response to space and time limitations. I fear that occasionally, educators and administrators have found it so difficult to keep young children who are accustomed to watching television while they eat engaged that the periods have been shortened to minimize the chaos.

Here in Maine, the governor has just announced plans to offer free breakfast and lunch to every student in response to a federal initiative. If we intend to make nutrition a cornerstone of the educational process this study from the University of Illinois at Urbana-Champaign suggests that we must do more than simply provide the food at no cost. We must somehow carve out more time in the day for the children to eat a healthy diet.

But, where is this time going to come from? Many school systems have already cannibalized physical education to the point that most children are not getting a healthy amount of exercise. It is unfortunate that we have come to expect public school systems to solve all of our societal ills and compensate for less-than-healthy home environments. But that is the reality. If we think nutrition and physical activity are important components of our children’s educations then we must make the time necessary to provide them.

Will this mean longer school days? And will those longer days cost money? You bet they will, but that may be the price we have to pay for healthier, better educated children.
