Cauliflower is a cultivar that doesn't occur naturally. Our bodies were therefore not designed to eat cauliflower. While scientists say there is no evidence that cauliflower is unsafe, they said that about smoking cigarettes and they were REAL wrong.

It's terrible reasoning, you can do that for almost everything we ingest in one form or another. I've seen people make the same claims for cooking food, insisting everything has to be raw.
