Well yes, I can't really remember every paper that I have read. I do read a lot on various subjects. I am sure an internet search would  give it up, but I don't have the time to search for it.

Besides it's not a life decision, it's more like a non-decision. Omnivore diet is the normal, and I have no reason to change that unless I find sufficient evidence on the contrary.

I will look more deeply into veganism later.
