The nutrition transition, food retail transformations, and policy responses to overnutrition in the East Asia region: A descriptive review

Summary Background The East Asia region is facing an increasing burden of overweight, obesity and related noncommunicable diseases, resulting from an ongoing nutrition transition. This study aimed to document the growing burden of overweight and obesity, and the accompanying dietary shifts, in the East Asia region and describe the policy responses to this. Methods We present noncommunicable disease risk factor collaboration data on trends in the burden of malnutrition, and Euromonitor International data on trends in dietary purchases, in the East Asia region. We searched the NOURISHING and GINA databases to identify food and nutrition policies implemented in these countries. Results There is an ongoing nutrition transition in the East Asia region, notably in upper‐middle and lower‐middle income countries. The prevalence of overweight, obesity, and accompanying health conditions, purchases of ultra‐processed foods and beverages, and purchasing from supermarkets, fast‐food and takeaway outlets, and other convenience retailers, are increasing. The policy response to this nutrition transition is limited, with the majority of policies implemented in higher‐income countries. Conclusions East Asian countries are facing a growing burden of malnutrition, due in part to the dietary shifts occurring here. An ecological approach to policy intervention is needed to drive transformative food systems change.
