Behavior or environment can trigger chemical modifications in the body that affect which genes are turned on and off, the study of which is known as epigenetics. In the new study, published inHuman Molecular Genetics, tea drinking for women was associated with epigenetic changes in 28 different gene regions known to interact with cancer or estrogen metabolism.
