Plant-based food taboos in pregnancy and the postpartum period in Southeast Asia – a systematic review of literature

Purpose Food taboos during pregnancy and the postpartum period have been linked to increased risk of maternal and neonatal death. This paper aims to present plant-based food restrictions on Southeast Asian women during pregnancy and after giving birth and the rationale behind such cultural practices. Design/methodology/approach Google® Scholar, PubMed and Scopus search using the term food taboo, its synonyms and truncations, in combination with the terms pregnancy, postpartum and breastfeeding, and with the name of the Southeast Asian countries, was conducted from January to February 2017. Articles were included in the review if their full texts were accessible online, in English, published from 2005 to 2016 and if they contained primary data from either quantitative or qualitative method. Findings A total of 281 articles were downloaded, and 28 were included in this review. The food taboos and the reasons for avoidance were collated and grouped per their occurrence and according to the country or countries where they are practiced. In total, 14 papers generated data on food taboos during pregnancy, 16 papers on postpartum food taboos and/or 6 on breastfeeding. Research limitations/implications This review pools together relevant information about plant-based food taboos Southeast Asian women adhere to during pregnancy and after giving birth. However, data are absent for some of the Association of Southeast Asian Nations (ASEAN) countries, and there is a need for more research to get up-to-date information on the local women’s adherence to these cultural practices. Practical implication The knowledge of these practices can support stakeholders who are contributing to the reduction of maternal and under-five mortality ratios in Southeast Asia. Originality/value This is the first review paper on food taboos covering all ASEAN members and highlighting the need for cultural sensitivity to properly address maternal and child health problems in the region.
