The "Dutch Hunger Winter"

In the winter of 1944, around 30,000 people died in the Netherlands due to a famine. At that time the weather was unusually severe, agricultural land had been ruined by the war, and the people were already short of food. It was found out that women who were pregnant during that time had smaller/underweight babies. This was no surprise, the surprise was that when those babies grew up, even though the war was over, they had been well fed and no genes had been tinkered with, they went on to have underweight babies themselves. Detailed birth records collected during the "Dutch Hunger Winter" allowed scientists to analyze the long-term health effects of prenatal exposure to famine. This finding is remarkable because it suggests that a pregnant mother's diet can affect her health in such a way that, not only her children but her grandchildren and possibly generations even further down the line could also inherit the same health problems.
