Women in low- and middle-income countries are known to make changes to their diets during pregnancy. We set out to explore the subject of traditional pregnancy diets with a view to finding out if migrant women follow these practices, and if such information might help explain differences in birth outcomes between migrant women and destination-country-born women. This review found that traditional pregnancy diets vary from region to region, that migrant women may follow some of these practices, and that there is a dearth of studies looking into the impact of pregnancy diets on birth outcomes.
