I always thought that your genes were sort of like your fingerprint — you get what you get, and you cannot change it. While this may be basically true, the field of Epigenetics helps us to understand how our behavior, environment, and other factors can alter how our genes express themselves, or change which genes get switched on or off. This has important ramifications for those faced with a genetic disorder or a family history of a certain disease. It is also important for those who simply want to live a healthier lifestyle. Listed below are five titles that incorporate Epigenetics into a plan for healthy living. For additional information on Epigenetics, try Medline Plus or Centers for Disease Control.
