I'd like to go over the subject of soy and what forms of soy are good for you and which ones to avoid. There was a time when I avoided soy almost completely because I thought soy was bad. That is not the case and I was missing out on the very beneficial qualities that some soy products like tofu, tempeh, miso, tamari, soy sauce, whole soybeans and natto offer. These are the soy products that are good and can be eaten fairly freely within moderation. Tempeh, miso, natto and tamari are fermented soy. Fermenting soy creates good bacteria and health promoting probiotics to keep us well. It also reduces the estrogen content in soy foods. The soy to avoid is highly processed soy, especially soy isolate protein. Soy isolate protein has been linked to, some serious, and some not so serious, health issues. If possible please avoid soy milks (most), soy cheeses, soy powders (like soy baby formula and soy protein powders), soybean oil (often labeled as vegetable oil), packaged products that include soy ingredients, etc. Look for alternatives and stick with fermented soy products or buy tofu, whole soybeans and soy sauce as they are beneficial. And buying organic or at least non-GMO soy products is important as well. They do not cost much more and is well worth the few extra cents especially because soy can be very inexpensive...at least tofu is. So enjoy your crispy pan fried tofu or tofu scrambles, and use soft tofu in smoothies, cheeses, sauces and dressings....but do use it in moderation and not at every meal. Make your miso soup or use miso in dressings and enjoy the added benefits of vitamin B12, a good source for vegans, plus it's ability to aid the digestive tract. 

Below are three articles that you can read at your leisure. They will explain much better than I can. I always recommend for you to do your own research. Everything is out there just waiting to be found and I want to pass along the information that I find in hopes that we can all create good healthy habits for ourselves and the world around us.
