Description

Healthy school lunch initiatives modify the food environment during school lunch periods, prominently displaying, marketing, and increasing the convenience of healthy foods and providing many healthy options, especially fresh, whole foods and foods cooked from scratch. Healthy school lunch initiatives can focus on food served through the National School Lunch Program (NSLP) as well as competitive or à la carte offerings. Under the Healthy, Hunger-Free Kids Act (HHFKA) of 2010’s strengthened nutrition standards, NSLP meals include more whole grains, fruits and vegetables, low-fat milk and dairy products, and less sodium and fat than previous years (USDA-HHFKA). Regulations for the availability and nutritional content of competitive foods vary by state and community. 

Expected Beneficial Outcomes

Increased healthy food consumption
Increased healthy food purchases
Improved dietary choices
Improved nutrition
Improved weight status
Increased academic achievement
Increased food security

Evidence of Effectiveness

There is some evidence that healthy school lunch initiatives increase healthy food selection and consumption, and improve students’ eating behaviors (Driessen 2014, Williamson 2013, Cohen 2013, Hanks 2013). Such initiatives can also improve childhood nutrition (Williamson 2013). Additional evidence is needed to confirm effects (Driessen 2014).

Small modifications to the school lunch environment that are appropriate to the age of the students, such as pre-slicing fruit in middle schools and giving vegetables appealing names (e.g., X-Ray Vision Carrots) in elementary schools can increase students’ selection and consumption of healthy food, and decrease plate waste (Wansink 2013, Wansink 2012). Verbal prompts alone can also increase fruit consumption (Schwartz 2007). Students participating in Chef Initiative healthy school lunch programs have been shown to consume more fiber, vitamin C, and vitamin A and waste fewer vegetables than peers in schools with traditional school lunches (Cohen 2013). Reducing availability of sugar-sweetened beverages and french fries as part of a healthy school lunch initiative is also associated with improved dietary intake (Briefel 2009). Healthy school lunch initiatives that combine cafeteria environment improvements with classroom nutrition education improve fruit and vegetable consumption and dietary choices more than cafeteria improvements alone (Song 2016).

Healthier school lunches can improve academic outcomes and reduce authorized absences related to illness (Belot 2011). Healthy school lunch initiatives have been associated with increased free National School Lunch Program (NSLP) participation (Wojcicki 2006). Many school districts report increased participation following implementation of the Healthy, Hunger-Free Kids Act of 2010 (HHFKA) (USDA-HHFKA implementation 2014, PEW-School food 2012).

Schools with a majority of students (two-thirds or more) eligible for free and reduced-price lunch (FRPL) report more participation in healthy school lunch programs and less plate waste than schools with fewer FRPL eligible students (BTG-Terry-McElrath 2014). Offering healthy, culturally relevant foods can increase participation in such programs (Wojcicki 2006); a culturally sensitive approach is suggested to increase effectiveness of obesity prevention efforts such as healthy school lunch initiatives (CDC-Health equity resources, NRC NPAA-Cultural diversity).

Early examinations of HHFKA suggest that strengthened school lunch standards increase fruit consumption, reduce plate waste (especially vegetables and entrees), and do not change milk consumption (Schwartz 2015). Surveys suggest that changes in plate waste may vary, with the least waste reported at urban and suburban elementary and middle schools with a large proportion of students from lower income families (BTG-Terry-McElrath 2014). Careful implementation of HHFKA and healthy school lunch initiatives is necessary to maintain gains in food security realized through the NSLP (Gundersen 2015).

Many aspects of healthy school lunch initiatives are low cost, easy to implement, and scalable, such as appealing names, attractive displays, verbal prompts, and pre-slicing (Wansink 2012, Wansink 2013, Schwartz 2007). Cooking from scratch can also be cost-effective; lower food costs and higher labor costs often lead to small changes in total costs (Woodward-Lopez 2014). Inadequate equipment, kitchen infrastructure, and staff training to support new cooking, food safety, equipment operation, and healthy food promotion responsibilities along with revisions to menu development and food purchasing processes can be challenges for healthy school lunch initiatives (PEW-Urahn 2013).

Implementation

United States

As of 2013, 28 states and Washington DC have authorized funding for school nutrition grants to improve the school food environment or passed school nutrition legislation. These state actions complement the new nutrition standards outlined by the 2010 federal Healthy, Hunger-Free Kids Act (HHFKA) (NCSL Winterfeld-Obesity prevention 2014). According to the USDA, over 90% of schools already meet the new HHFKA standards, and only 0.15% of schools have opted out of the NSLP following implementation (USDA-HHFKA implementation 2014).

More public elementary schools offered school lunches with healthy foods in the 2013-14 school year than the 2006-07 school year. The portion of schools serving whole grains, for example, increased from 76% to 97%, those serving vegetables (other than potatoes) increased from 74% to 83%, fresh fruit from 61% to 80%, and the portion of schools with salad bars increased from 17% to 31%. Unhealthy foods also decreased during this time period. Just over half (53%) of elementary schools always offered fried potatoes (73% in 2008-09); 37% of schools always offered higher-fat pizza (down from 70% in 2010-11), and 35% of schools always offered higher-fat milk (down from 79% in 2006-07) (BTG-Turner 2015).

Many non-profit organizations support healthy school lunch initiatives. The Alliance for a Healthier Generation, for example, supports efforts in over 28,000 schools, touching every state (AFHG-Lunch). Santa Barbara’s School Food Initiative features a Culinary Boot Camp and kitchen staff training to bring cooked from scratch lunches into Santa Barbara public schools (Orfalea-School food). In Massachusetts, Project Bread’s Chefs in Schools program helps school kitchen staff learn to prepare healthy meals and supports farm to school efforts (Project Bread-Schools). Let’s Move Salad Bars to Schools has donated over 4,000 salad bars to schools across the country (Let's Move-Salad bars). In Colorado, The Lunch Box’s Rainbow Day program encourages students to eat from the salad bars in their school lunchrooms (The Lunch Box-Rainbow days). 

Wisconsin

Wisconsin’s Team Nutrition provides school foodservice professionals training and technical assistance towards healthy school meals and supports healthy school lunch programs throughout the state (WI DPI-Team nutrition). The Chetek-Weyerhaeuser School District is an example of a district with a healthy school lunch initiative; the initiative was part of a series of changes that lead to a declining rate of overweight and obesity for children in grades K-12 (RWJF-WI progress 2015).
