    Abstract

    The prospective cohort study examined whether Ecuadorian women with early pregnancy nausea and vomiting (NVP) are more likely to develop food aversions and cravings, and if so, whether the specific foods identified as aversive or craved are the same as those predicted by the popular maternal-embryo protection hypothesis (MEPH). Consistent with MEPH predictions, women with NVP were more likely to report increased odor sensitivity and aversions for some predicted "toxic" foods and more likely to crave fruits. However, other hypothesis predictions were not supported. The relationship of food aversions and cravings with NVP appears more complicated than that explained by the MEPH.
