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. I've been hearing this negative information on soy for so long, but it defies common sense. Japanese live the longest of anyone on Earth, and they eat tofu and edamame nearly every day.
Now, are there people who shouldn't eat soy? Yes -- it's a common allergen, for one thing.
