Transitioning food environments and diets of African migrants: implications for non-communicable diseases

Non-communicable diseases disproportionately affect African migrants from sub-Saharan Africa living in high-income countries (HICs). Evidence suggests this is largely driven by forces that include migration, globalisation of unhealthy lifestyles (poor diet, physical inactivity and smoking), unhealthy food environments, socio-economic status and population ageing. Changes in lifestyle behaviours that accompany migration are exemplified primarily by shifts in dietary behaviours from more traditional diets to a diet that incorporates that of the host culture, which promotes the development of obesity, diabetes, hypertension and CVD. The current paper presents a critical analysis of dietary change and how this is influenced by the food environment and the socio-economic context following migration. We used a food systems framework to structure the discussion of the interaction of factors across the food system that shape food environments and subsequent dietary changes among African migrant populations living in HICs.

Automated summary

Non-communicable diseases have a greater impact on African migrants from sub-Saharan Africa living in high-income countries. This is largely due to factors such as migration, globalization of unhealthy lifestyles, unhealthy food environments, socio-economic status, and population aging. Changes in dietary behaviors accompanying migration, primarily shifting from traditional diets to the host culture's diet, contribute to the development of obesity, diabetes, hypertension, and cardiovascular diseases. The paper critically analyzes how dietary changes are influenced by the food environment and socio-economic context following migration, using a food systems framework.
