Because of how much of it is added into every alternative meat replacement product, and it's a shockingly high amount if you read the labels on some "organic" and "plant-based" products.
I have a few issues with this. As far as I know health concerns related to meat replacements aren't to do with sugar levels, probably more likely with saturated fat and sodium (which exists in regular meat too). Also I don't know why you bothered to put organic in there as well since the we're talking about meat replacement. Finally I think you're making the assumption that if we don't eat meat we need meat replacements at all.
