Does knowing more about nutrition help people make more nutritious choices? That's the question that Dr. Erin Dancey, a faculty member in Durham College's (DC) Fitness and Health Promotion program and research lead with the Social Impact Hub, set out to answer in a recent study evaluating the changes in nutrition literacy in students taking introductory nutrition courses.
Turns out, yes. In this case, the nutrition courses had a positive impact on students' nutrition literacy, with both domestic and international students showing significant improvements in their ability to understand and apply information about healthy nutrition. The nutrition courses covered various aspects of healthy eating and dietary behavior in alignment with Canada's Food Guide.
Other findings that stood out included an upward trend in wellness, especially among international students. However, the study also revealed food insecurity, referred to as a lack of consistent access to enough food for an active, healthy life, emerged as a negative impact on academic success.
Supported by the Centre for Teaching and Learning, the study recruited students in the Fitness and Health Promotion program who were taking an introductory nutrition course, plus students from the Dental Hygiene program enrolled in a similar course. The study was inspired by the observation that a lot of international students seemed to struggle to navigate new food pathways, such as where to find nutritious food.
Students participated by responding to standard questionnaires on the topics being explored, including nutrition literacy, household food security and a wellness inventory. They took the questionnaires as a baseline at the start of the course and again at the end to measure growth in their knowledge.
Dancey says the findings of this study have important implications for educational planning and support systems at DC and beyond. "The biggest takeaway from this study was the negative correlation between food insecurity and academic success and the importance of increasing access to food resources for at risk students. Learning more about nutrition literacy, understanding what constitutes healthy food, where to access it, and how to prepare it are all important for students to know," said Dancey.
At DC, Dancey notes that nutrition literacy resources are available at the Campus Health and Wellness Centre and The Barrett Centre of Innovation in Sustainable Urban Agriculture, for example through their FoodIQ campaign that includes a food security and literacy toolkit. Calling attention to these existing resources and looking for places to develop more and increase nutrition content in courses will help to make nutrition literacy more mainstream.
Meanwhile, Dancey is also working on exploring nutrition literacy in other contexts, with a current study supported by DC's Social Impact Hub that looks at the impacts of a newcomer community kitchen program created by the Community Development Council of Durham. The study will be published on the Barrett Centre Portal in the new year.
