Epigenetics

Hi all. I am new to Dr. Joes teachings and what brought me here is an attempt to heal my body from various issues. The main thing that peaked my interest is DJ explaining how through his works one can silence specific degenerative inherited genes. Does anyone have any advice on where to start with this? I know it’ll take time and work but I believe I can do this because the science and testimonies are there so I know it’s possible I just need to know where to start and where to go from there. I have already started living his teachings but with only the basic knowledge from any free content I can find of his. Any help would be greatly appreciated!
