Juice displaces milk and fruit in high school lunches

High school students participating in school meal programs are less likely to select milk, whole fruit, and water when fruit juice is available, which on balance may decrease the nutritional quality of their lunches, according to a new study by the Rudd Center for Food Policy and Obesity at the University of Connecticut.

The National School Lunch program reaches over 30 million students, and while fruits, vegetables, and dairy served in the school lunch undoubtedly contribute to a healthy diet, the appropriate role of juice in children’s diets has generated debate. Currently, the American Academy of Pediatrics recommends that children aged 7-18 consume no more than 8 ounces of juice daily, and juice is permitted to be served as part of the National School Lunch program only on certain days.

“Our findings suggest that on the days when juice is available as a choice in high school lunches, students do not select whole fruit and milk as often. This is a problem because compared to juice, milk and whole fruit are better sources of three nutrients of concern for adolescents—calcium, vitamin D, and fiber,” says Marlene Schwartz, Director of the UConn Rudd Center and co-author of the study.

The study, published in the Journal of Nutrition Education and Behavior, utilized cafeteria register data from 3 low-income, Northeast high schools over one school year to determine whether high school students select different meal options on days when juice is available. The study also looked at the sales of a la carte beverages, which included both water and 100% juice.

Key findings include:

  • On juice days, 9.9% fewer milks and 7.4% fewer whole fruit servings were selected with lunches.
  • 8.2% fewer bottles of water and 24.4% fewer bottles of 100% juice were sold a la carte when juice was offered.
