Food access, dietary acculturation, and food insecurity among international tertiary education students: A scoping review.

The number of international students within tertiary education facilities continues to increase globally, but the challenges for this population in achieving a healthy diet in an unfamiliar environment receives insufficient attention. This scoping review aimed to synthesize current literature that investigated dietary changes and food security status of this student population. We followed a five-stage methodological framework developed by Arksey and O'Malley. Six electronic databases were searched. All types of research methods, including qualitative, quantitative, and mixed methods, were considered for inclusion. This review included 30 articles reporting dietary changes and 12 articles reporting food insecurity in international students. The students were able to explore novel foods in their host country without totally abandoning their original diet, thus developing a hybrid diet. Dietary habits oscillated between the new and traditional dietary cultures with many students consuming foods from their new food environment but less so in the long term. Changes in diet may contribute to weight change and some negative health impacts, but none of the included studies investigated the effects on academic performance. Additionally, international students appeared to be more vulnerable to food insecurity, but the contributing factors and impacts of this issue were insufficiently researched. International students often experienced dietary acculturation and faced more challenges in food security than their domestic peers. More specific support should be provided by tertiary institutions and governments to international students including regular culturally appropriate nutrition education programs.
