Amazing research on vegan diets and metastatic cancer.
In designing an antibiotic, you couldn’t create a drug that destroyed DNA, for example, because that’s something that both humans and bacteria share in common. It would kill bacteria, all right, but it might kill us, too. Instead, many antibiotics work by attacking bacterial cell walls, which is something bacteria have that we don’t.
Antifungals can attack the unique cell walls of fungus. Pesticides can work by attacking the special exoskeleton of insects. But fighting cancer is harder, because cancer cells are our own cells. So fighting cancer comes down to trying to find and exploit differences between cancer cells and normal cells.
Forty years ago, a landmark paper was published showing for the first time that many human cancers have what’s called absolute methionine dependency, meaning that if you grow normal cells in a Petri dish without given them the amino acid methionine, then normal cells thrive; but without…
