Can Diet and Exercise Affect Your Genes?

17:20 minutes

DNA has been called the building blocks of life, the blueprint that we’re born with that maps out the on/off switches for genes that are hardwired into our cells. The field of epigenetics looks at how exercise, diet, and other environmental factors can affect how those genes are expressed. Andy Feinberg, Director of the Epigenetics Center at the Johns Hopkins University of Medicine, and Carl Johan Sunderberg, a molecular exercise physiologist, discuss the latest in epigenetics research and how it might lead to new treatments.
