I've written a blog or two previously on the NORI protocol, an approach to cancer treatment that restricts dietary levels of methionine more aggressively than this, and adds a cocktail of "nutraceuticals" that have been shown in various studies to trigger apoptosis (cell death) in cancer cells only, with no harmful effect on the trillions of healthy cells that comprise the body.
The diet Dr. Witkowski recommends here, a standard whole foods plant based diet, is thought to be cancer preventative, while the NORI Protocol is designed to treat cancers that are already malignant.
I was curious about Dr Witkowski so I looked for the web site he mentions here. It appears to have morphed into a different web site, where I found his "my story" page.
