Dangerous quack science. Convincing people of it has the very real potential to kill people.

Well, I could link you to a bunch of studies that say otherwise, but then you would tell me all the reasons that those studies are bogus, and then show me a bunch of studies that show there is no connection (probably sponsored by those peddling chemotherapy et al.), so I guess we'll just avoid the rathole and stay convinced of our own opinions :)

"peddling chemotherapy"

This is the most stupid and obnoxious thing I've ever seen on HN. Chemotherapy saves lives every day. You can believe that good diets are healthy and helpful for sick people without insulting people that sell nasty but powerful medicine that is proven to work.

Agreed. Posting those two comments was a mistake.

Don't worry, I've got your back; I'll do it for you, dougk16.

Link me to some peer-reviewed studies that show that cancer can be cured with only dietary changes.

Link the (peer-reviewed) articles, rather than guessing peoples responses to the hypothetical articles.
