I visited your link. That really took me back! In the late 60s and early 70s a common greeting was, "What are you eating?" rather than "How are you doing?" I ate enough raw steel cut oats for breakfast to gag a herd of horses, enough raw lunches and dinners to forever compromise my digestive system, did enough juice fasts, and made enough alkalinizing soups to last me the rest of my life. I tell ya, we aren't built to eat a lot of raw onions. So been there, done that over 40 years ago. But enjoy yourself. I'm sure my grandparents couldn't have dissuaded me from what I was doing, either.

However, and this is a big however, it is now very dangerous to eat raw meat like some on your link advocate. Don't do it.
