The point isn't to compare one specific product to one specific product; you compare a holistic diet with a holistic diet. If I got 50%+ of my protein from seitan sausage, cautioning against processed foods might be relevant, but nobody actually eats that way. (Also, what harm does physically processing foods in machines actually do? Adding salt in the factory and running it through an extruder is no worse than adding salt at home.)

What percent of the chicken an omnivore eats is organic? Do people who say "I only eat organic chicken and beef from my uncle's special farm" never eat at restaurants or friends' houses? Never buy TV dinners? Omnivores seem to enjoy comparing the best theoretical meat-based diet with the worst theoretical plant-based diet, regardless of how people actually eat.

You kicked off this thread with "Gluten is still not considered perfectly safe if as well you read the literature," and are now not providing links to the literature that you told me to read. I'm asking for evidence that gluten is "not safe."
