- Societies in which morning sickness was not observed will be significantly more likely to have (i) only plants as a food staple, (ii) corn as a staple, and (iii) corn as the only staple than societies in which morning sickness was observed (129).Flaxman, Samuel M. - Morning sickness: a mechanism for protecting mother and embryo, 2000 - 4 Variables
Pregnancy sickness is characterized by nausea, vomiting, and food aversions during pregnancy, particularly during the first trimester. Previous work has asserted an adaptationist explanation for this phenomenon: pregnancy sickness protects the embryo from the toxic compounds found in many foods via expulsion (i.e., vomiting) of potentially dangerous foods and by encouraging aversions to foods likely to harbor toxins or pathogens. The authors reexamine 27 small-scale societies previously investigated by Minturn and Weiher (1984) for evidence of pregnancy sickness and food aversions in light of the fetal protection hypotheses.
