Plant-based diets may prove to be a useful nutrition strategy in both cancer growth control as well as lifespan extension, because these diets are naturally lower in methionine.
Methionine restriction—best achieved through a plant-based diet—may prove to have a major impact on patients with cancer because, unlike normal tissues, many human tumors require the amino acid methionine to grow.
A higher rate of cancer deaths among those that handle and process meat is attributed to infection with viruses, and chronic exposure to animal proteins.
