Red meat contains branched-chain amino acids that can prevent mTOR activation and TMA, which the liver converts to TMAO, a molecule that accelerates cardiovascular disease and cancer.

“One of the things that's not appreciated about red meat. And I'll just mention this is that it's not just that they have more of these three branched-chain amino acids that prevents mTOR from doing its good stuff to the body. There's also a molecule called TMA that is in the meat that goes into the bloodstream, the liver turns it into a toxic molecule called T-M-A-O. And this TMAO is showing, at least in animals, probably in people, to enhance, accelerate cardiovascular disease.”
