In the UK, the main suppliers of soya based products - Alpro, Cauldron Foods, Linda McCartney Foods, are all GM free.
Unless you are eating raw beans then there will be a level of processing involved. I don't see this is a bad thing! Most of the soya crop in the world is grown for feeding animals for slaughter so that adds another layer of processing. I prefer to cut out the middle man for protein.
I eat or drink soya daily and am happy to do so as it is low carb/high nutrition. I am a female who recently lost her ovaries so I welcome the plant estrogens it contains. Phytoestrogens can be found in many other low carb favourites such as flaxseeds, walnuts, cauliflower and broccoli.
I am happy with both my diabetes and hormone control at the moment.
