I use Kroeger's Organic tofu by Simple Truth and Safeway's Organics. I also love Soy Curls by Butler Foods. Butlerfoods.com. Are these acceptable sources of soy?
Without seeing each label, here is John's guideline for soy. This can be found on page 28 of our Master Plan Manual. This is a simple guideline John uses, and I believe this will be helpful. If you need further clarification, simply send us a label for his opinion.
