Carbon footprint of food you buy

Never heard of "aminos" but an "invented" food puts me off!
" Liquid aminos are an unfermented liquid soy product invented by health food pioneer Paul Bragg and is a soy sauce alternative preferred by many health aficionados."

I like firm tofu, sliced into...........erm, slices, dipped in soy sauce and coated with sesame seeds - then fried until crusty.

Well, presumably someone invented soy sauce in the dim and distant past 

Mmm, crusty tofu!
