I think that's a compelling argument, but I find I'm still cautious about anything that we're eating, especially as a staple good. It's just extremely difficult to _know_ what the long-term effects of any significant change in diet will be for any creature, and in particular for us humans it's hard to be an outside observer since by definition we don't live long enough to observe multiple generations. There have been a lot of things that science thought were "harmless" or even "good for us" in the 20th century which we later realized was quite harmful. I see no reason to think that we've passed some magic threshold where we no longer make such mistakes.
