I'm disappointed they switched away from seitan / gluten protein to soy protein. I just like wheat protein better, it feels better to me. But there's tremendous--and unfounded--pressure to eliminate gluten. Sad.
It's not unfounded ... for whatever reason, it seems very few people are allergic to soy, whereas more than 1% of population (Americans ? not sure) have 'allergies' to gluten.
My daughter has diagnosed celiac disease, so I'm glad for any pressure to eliminate gluten :) I'm also amazed at how many things you wouldn't imagine have gluten :(
