Science and the medical community are finally catching up to our elders and "raw foodies" who have, for years, claimed that eating your [natural non-GMO] vegetables will keep you healthy. I can't remember it now, but I watched a convincing movie several years ago where a collection of last-resort cancer patients went into seclusion on a raw food diet and most (if not all) returned cancer free.
I have to say, that the secondary benefit of healthy eating might be reducing obesity, gave me a "duh!" reaction. Anyway, ridiculously interesting, you really should watch it.
