Deep Diver, the Japanese, Vietnames, Thai peoples, Chinese, and Indonesians have been living largely on soy for protein for longer than any western civilization has existed. Shouldn't they all be dead? Granted, in
Indonesia, it's mostly tempeh
, but in
China and Japan it's mostly tofu, which is not fermented, soy milk, which is not fermented, edamame, which is not fermented. Miso is eaten in very small quantities.
