During pregnancy, many women report feelings of disgust toward ordinary foods, and cravings for particular foods. The purpose of this study is to answer questions about the socioecological, environmental, psychological, and adaptive influences of such dietary shifts in pregnancy. Specifically, this study aims to answer the following questions: 1) What role does social learning (culture) and social norms have in the types of foods/non-foods that are craved and avoided during pregnancy? 2) Do environmental factors, such as resource scarcity (i.e. food insecurity) and pathogen risk, influence putative dietary shifts in pregnancy? 3) What role does nausea and vomiting in pregnancy (NVP) have in predicting dietary shifts?
