Serving healthy choices in the lunch room, limiting availability and marketing of unhealthful foods and sugary drinks, and making water available to students throughout the day are some of the ways that schools can help prevent obesity. Making these types of changes in the school food environment will be no easy task, however. In the U.S., for example, the Department of Agriculture recently finalized comprehensive new school meal guidelines that will increase vegetables, fruit, and whole grains and curb sodium, saturated fat, and trans fat. (1) But due to political pressures, the agency was not able to fully implement the meal guidelines recommended by an expert panel at the Institute of Medicine. (2) (Read more about the political battles over school lunch, on The Nutrition Source website.)
Now that the new nutrition standards are on the books, will schools actually be able to meet them? It may be difficult to answer that question, since compliance is not strictly monitored week to week. And schools and face many other challenges to creating a food environment where the healthy choice is the default choice. Among the obstacles: budgeting for the higher costs of purchasing and preparing more healthful foods; coaxing children to accept the more healthful options; and addressing the multitude of ways that unhealthful foods and drinks are sold or served outside of school meals, from classroom birthday parties to school-wide bake sales and sporting events.
Here is a summary of obesity prevention recommendations for school meals and the school food environment, based on a review of expert guidance from the Centers for Disease Control and Prevention, the Institute of Medicine, the World Health Organization, the School Nutrition Association, the American Heart Association, and others. For more detailed guidance on these recommendations and ideas for putting them into practice, explore the source list and the links to other resources.
