Epigenetics refers to the study of how genes are expressed. Scientists have found a definitive link to conditions in the womb and what genes are expressed later on in life. Methyl groups are known as gene silencers and they are programmed in the womb. These groups of DNA can stop certain genes from being used and expressed.One specific phenomenon was the Dutch Hunger Winter of 1945. It was found that women who were pregnant during the famine gave birth to children who were at higher risk for obesity and diabetes later on in life. Their children’s bodies had learned to latch on to nutrients at a higher rate in the womb and continued to do so even in old age. More on this topic can be found in my Now Comment page: .
