Pregnancy is often described as one of the most cooperative ventures that a woman can experience in her lifetime. But when one considers the biological changes that occur during pregnancy, it becomes clear that pregnancy is not as cooperative as it seems on the surface. The current research uses a genetic conflict framework to predict how underlying conflict between mother and fetus over resource transfers is expected to alter eating behavior and food preferences, and how these changes in eating behavior and preferences should then be associated with certain pregnancy complications. Across two studies, women who had recently had a baby (Study 1) or were currently pregnant (Study 2) recalled changes in their eating behavior during pregnancy as well as any pregnancy complications they experienced during that pregnancy. Providing partial support for the hypotheses, women who reported increased vomiting in response to maternal-favoring foods were more likely to experience preeclampsia during pregnancy. In addition, the results provided preliminary evidence that changes in pregnancy eating behavior were associated with an increased the likelihood of experiencing high blood pressure, gestational diabetes, and infections during pregnancy. Taken together, these studies show that the framework of genetic conflict makes testable predictions about the relationship between eating behavior in pregnancy and pregnancy complications, and that several pregnancy complications that are relevant to genetic conflict (high blood pressure, pre-eclampsia, gestational diabetes, and infection) are associated with changes in eating behavior in pregnancy. Future research should continue to investigate how genetic conflict influences the relationships between pregnancy eating behavior, pregnancy complications, and how these associations impact postpartum health.
