I'm learning ALOT on Dr. Medicis' website.. www.straighttalk.cc .a virtual goldmine of helpful information...one is an article about how scientists are looking to the microbiome to determine DNA expression.... also if you are really curious about your own gut chemistry here is a great lab test he suggested on one of his videos about gut health: https://www.gdx.net/product/gi-effec...ive-stool-test
