Addressing the Obesity Epidemic
Offering nutritious snack foods can be effective without decreasing the number of snacks sold and while maintaining financial stability of school food service programs.
♠ Inﬂuencing Healthy Snack Selection by Middle and High School Students
The obesity epidemic is well-documented in our society. Among the contributing factors is the high level of American children’s of snack foods and beverages that contain added sugars and oils. Schools can play an important role in shaping children’s lifetime dietary habits by providing nutritious foods and teaching them to make wise food selections. The school vending machine is one place where schools can have an impact on the quality of foods offered. To assist schools, registered dietitian Jaime Foster of the college’s Department of Human Nutrition and OSU Extension Family and Consumer Sciences joined with Columbus Children’s Hospital to design a practical tool to measure the nutritional value of vended snack foods. The goal was to create a research-based vending machine software program—with corresponding educational materials—that would positively inﬂuence students to make nutritious choices.At the same time, the partners wanted to show that offering nutritious snack foods can be effective without decreasing the number of snacks sold and while maintaining ﬁnancial stability of school food service programs.
♠ A Rating System Educates Kids about Choices
Working with Children’s Hospital staff, Foster helped create a nutrition rating system for processed foods offered in vending machines. The computer software program gives you an easy way to enter nutritional data and learn the category of snacks. Green means “best choice,”yellow signals “choose occasionally,”and red warns “choose rarely.” Unlike many rating programs, the program, which is called Snackwise,evaluates more than the calories, fat, saturated fat, and sugar content of processed foods. It also evaluates the following desirable nutrients that adolescents need for healthy development:
• Vitamin A
• Vitamin C
Educational labels coded red, yellow, and green on the vending machine and on the products educate the purchasers about their choices. Snackwise also offers ﬂexibility, which again sets it apart from other nutrition rating systems. School administrators can offer a variety of snacks in each category, promoting healthier snack selections without compromising sales or ﬁnancial stability. By offering a variety of choices, administrators encourage interest in healthier options while they maintain control over what is offered.
♠ Survey Results:Encouraging Healthy Choices without Lowering Revenue
Deb Kellee, the DECA teacher at Bowling Green High School, Bowling Green, Ohio, learned about Snackwise from the OSU Extension Family and Consumer Sciences educator in her county, Doris Herringshaw. With guidance from Herringshaw, Kellee and her marketing students implemented the program at the high school. The Bowling Green students conducted a marketing campaign that went beyond the information provided at the school vending machine and focused on the new and healthy choices. They developed and administered a survey to their fellow students to learn the impact of their efforts and analyzed the data. Respondents were asked,
“If you chose a ‘green’ or ‘yellow’ snack, why did you choose it?”
A total of 56 percent said they chose it because they wanted a healthy snack or because they liked the snack. In the marketing campaign, the DECA students used a variety of marketing tactics, including the following:
- Educational posters in the halls and near vending machines
- A handout for all students and a letter home to parents at the beginning of the year
- A display case in the main hallway showing healthy options sold in the vending machines
The students’ survey showed that 59 percent of respondents were at least somewhat inﬂuenced by the educational campaign. A total of 64 percent said they noticed the rating stickers on the merchandise. Sales results for the three snack categories tell the most signiﬁcant story. At the start of the school year, the purchase of red foods was high. This trend declined in November and December, most likely due to holiday breaks. However, January through March saw a steady increase in the purchase of green and yellow foods and a decline in red foods. The volume of red food sales continued to drop for the rest of year. The sales figures also showed that after the nutritional vending machine program was initiated, sales volume from the machine was signiﬁcantly higher. In terms of overall revenue, the school actually saw positive revenue changes as a result of the campaign.
