Actually, the problem with tofu is that it has a very high fat to protein ratio. If I were to get my protein from tofu, I'd take in way too many calories from fat.
Yes, you are right - I left out highly processed foods (tofu, seitan, etc) because I don't think they are healthy.
The processing in tofu is merely blending of soy beans, filtering and curdling, unless cheese is in the same category for you, I'd say that particular millenia-old foodstuff is not in the same category as Beyond Burgers or hot pockets.
This is not the typical definition of "highly processed foods". I'm curious what you do eat.
