The Efficacy and Cost-Effectiveness of Replacing Whole Apples with Sliced in the National School Lunch Program

The National School Lunch Program (NSLP) serves 29.6 million lunches each day. Schools must offer ½ a cup of fruit for each lunch tray. Much of this fruit may be wasted, leaving the schools in a dilemma. The objectives of this study were to evaluate the consumption of whole vs. sliced apples and determine the cost-effectiveness of the intervention. Researchers weighed apple waste at baseline and three post-intervention time points in one rural Midwest school. The costs of the intervention were collected from the school. The cost-effectiveness analysis estimates how often apples need to be served to offset the costs of the slicing intervention. A total of (n = 313) elementary student students participated. Students consumed significantly more sliced as compared to whole apples in intervention months 3 (β = 21.5, p < 0.001) and 4 (β = 27.7, p < 0.001). The intervention cost was USD 299. The value of wasted apple decreased from USD 0.26 at baseline to USD 0.23 wasted at post-intervention. The school would need to serve 9403 apples during the school year (54 times) to cover the expenses of the intervention. In conclusion, serving sliced apples may be a cost-effective way to improve fruit consumption during school lunch.

Behavioral Health and Most-Interested Topics Among Older Adults in Three Aging-in-Community Programs in Florida

This study compares behavioral health and most-interested topics among older adults in three aging-in-community (AIC) programs: a university-based lifelong learning program (LLP; 38%), a county neighborhood lunch program (NLP; 29%), and a village program sample (33%) (total n=289). Mean age was 72.4 (SD=8.68) years. Although perceived health was similar (mean=3.76), LLP and village members reported higher quality of life than NLP participants (p=.004). Two-thirds of the participants indicated at least half of their daily plates filled with fruits and vegetables, and at least 10 min. walking in 4.5 days during a typical week. The duration of each walking was lower among NLP members (23 min.), compared with village (31 min.) or LLP members (35 min.) (p=.002). The top three most interested topics were brain health, giving back, and keep community healthy. Older adults in AIC programs were overall healthy and active. Results have implication on tailored program development.

Design of a distribution network for the school lunch program

The national school lunch program (NSLP) is crucial for providing healthy, inexpensive, or free lunches to children, thus benefiting society. Designing a distribution network for the program requires solving a location and routing problem. In this paper, first, we formulate a multi-objective non-linear integer programming formulation of the problem. Next, we develop a two-step approach since the problem is Np-hard. The first stage presents a K-mean clustering method that deals with routing decisions by determining the locations of food processing centers and allocating schools to these centers. The second stage offers a multi-objective mixed-integer linear mathematical model for finding the locations of distribution centers. Besides economic and environmental factors, we optimize travel time in the network as perishable items are involved. A weighted sum approach is presented for different weights of objectives. We provide a real case study in Turkey to demonstrate the applicability of the two-stage approach proposed in this study. The numerical results provide valuable information for decision-makers and authorities to prioritize and prepare action plans.

Authorship Correction: The Good Food for Learning Universal Curriculum-Integrated Healthy School Lunch Intervention: Protocol for a Two-Year Matched Control Pre-Post and Case Study (Preprint)

BACKGROUND Good nutrition affects children’s health, well-being, and learning, and schools offer an important setting to promote healthy behaviors that can last a lifetime. Once children reach school age, they spend more of their waking hours in school than in any other environment. Children’s eating habits may be easier to influence than those of adults. In Canada, households with children are more likely to experience food insecurity, and school food programs that are universally available to all children can support the development of healthy eating patterns across groups of varying socioeconomic status. There is a significant gap in the rigorous community-engaged academic research on the impact of school meal programs, especially universal ones. OBJECTIVE The aim of this population health intervention research is to study the impact of a 2-year universal, curriculum-integrated healthy school lunch program in elementary schools in Saskatoon, Saskatchewan, Canada, on food consumption, dietary quality and food and nutrition-related knowledge, attitudes, and practices. METHODS This population health intervention study will be conducted in 2 intervention elementary schools matched with 2 control schools. We will collect preintervention data, including objective measurements of food eaten at school and food-related knowledge, attitudes, and behaviors. This will be followed by the intervention itself, along with qualitative case studies of the intervention process in the 2 intervention schools. Then, we will collect postintervention data similar to the preintervention data. Finally, we will finish the data analysis and complete the ongoing sharing of learning from the project. RESULTS This study was funded in April 2020 but because of the COVID-19 pandemic, data collection did not begin until May 2021. The intervention will begin in September 2021 and end in June 2023, with end point data collection occurring in May and June 2023. The case study research will begin in September 2021 and will be ongoing for the duration of the intervention. CONCLUSIONS The opportunity we have to systematically and comprehensively study a curriculum-integrated school lunch program, as well as the promising practices for school food programs across Canada, is without precedent.

Nutrition Supports Deconstructed and Disrupted: An Evaluation of a Multilevel School-Based Intervention during the Time of COVID

The Best Food Forward (BFF) project aims to provide multiple nutrition supports and interventions to improve family food security (FS) and health outcomes associated with FS within two metropolitan school districts. A quasi-experimental time-series design guided a multilevel evaluation for BFF through surveys, biometric screenings, focus groups, and observations among a random sample of caregiver–child dyads. FS, utilization of school meal programs, and nutrition behaviors were observed and analyzed at three time points: preintervention, postintervention pre-COVID-19, and postintervention post-COVID-19. Participants included 122 parents and 162 youth. Families reported (1) an income less than $35,000 annually (48.8%) and (2) a COVID-19-related job loss (36.9%). Parents used Supplemental Nutrition Assistance Programs or Women, Infants, Children benefits prior to (51.1%) and following COVID-19 (50.0%). No significant differences in FS were found. RM-ANOVA indicated an increase in breakfast consumption at home and a decrease in use of the school breakfast program (F(1.78, 74) = 19.64, p < 0.001, partial η2 = 0.21) and school lunch program (F(1.51, 74) = 23.30, p < 0.001, partial η2 = 0.24). Rates of FS and eating behaviors did not change significantly over time. Correlations of program usage and eating behaviors demonstrate the importance of promoting participation in school meal programs. BFF may have prevented significant decreases in FS during COVID-19.

Evaluation of the National School Lunch Program at a Public Charter School in Duval County, Jacksonville, Florida, USA

The National School Lunch Program (NSLP) is the second largest meal program in the United States, operating in Elementary, Secondary and not for profit private schools. The goals and objectives of the NSLP is to provide free, healthy, nutritious and balanced meals to students each school day so they can develop into healthy adults. This study sought to assess whether the goals and objectives of the NSLP were being met. A mixed method with a convergent design was employed with a sample of 30 students and 2 staff. Findings revealed that majority of students believed that meals served are healthy, nutritious and balanced and are served timely. Majority of the respondents indicated that staff and servers in the school cafeteria are friendly and accommodating. It can be deduced from the findings that the school met the objectives of the program to a great extent but there is room for improvement since there are students who were served with nutritional foods but still did not consume portions of it. It is therefore recommended that the school incorporate healthy eating habits in the school’s curriculum including health education and promotions, which can help to boost consumption and increase the nutritional intake of vital nutrients in students.
