Tell It to the DNA

These studies have shown that when women are exposed to stress in the early stages of pregnancy, they give birth to children whose stress-response systems malfunction. Among the most widely studied of such traumatic events is the Dutch Hunger Winter. In 1944 the Germans prevented any food from entering the parts of Holland that were still occupied. The Dutch resorted to eating tulip bulbs to overcome their stomach pains. Women who were pregnant during this period . . . gave birth to a higher proportion of obese and schizophrenic children than one would normally expect. These children also exhibited epigenetic changes not observed in similar children, such as siblings, who had not experienced famine at the prenatal stage.
