I haven’t done a comparison of Beyond vs seitan for their nutritional value, but as someone who used to eat a lot more seitan I gleefully moved over to Beyond/Impossible. Seitan is packed full of gluten, which is much harder to digest. Seitan makes me uncomfortably bloated whereas Beyond/Impossible do not. And no, I don’t have a gluten “intolerance” or Celiac.

Seitan has 3x-5x the protein of beyond meat by weight. It sucks that your body processes it less. For me it’s usually a treat, and I’ve never noticed any digestive issues despite having issues with more whole wheat things (beer, more natural whole wheat breads).

I’m glad you like the beyond meat though. Good for them to have actual consistent customers for the 2x / year I end up eating it!
