One of the brands uses a generically engineered yeast to create a plant heme with a gene spliced in from soy. It's GMO but seems safe (its not like a round up ready GMO). I think these engineered meat substitutes may not be as healthy as a whole food plant based diet -- but I find it hard to believe they are less healthy or have a higher environmental impact that the meat they replace.
