Does Germany not have an ingredient list on food products? Unfortunately it's usual full of things we didn't evolve to eat, but that's the place to look
Also, while actual plants are pretty great, the "plant based" products aren't imo. I find that they are very processed. They aren't throwing the "plant based" label on the salad mix. Every now and then it's put on something that was already plant-based prior to the fad, like falafel, but that's not the norm. The label in itself is tantamount to non-meats "other than what we humans evolved to eat"
Chimpanzee's still eat meat as part of their diet, they don't eat highly processed soy topped with thickener laden vegetable oils.
