I’ve noticed a lot of items are marked as having ultraprocessed ingredients simply because they contain vital wheat gluten. This is actually something many people make themselves. It involve making bread dough and washing off the starch and leaving the gluten. Vital wheat gluten is a common ingredient in bread making, and can readily be bought. I’ve got a package of Bob’s Red Mill Vital Wheat Gluten in my pantry.
At the same time, Soy Protein Concentrate which is added to a lot of foods to make them “high in protein”, and involves a highly commercial process to produce is not considered an ultra-processed food additive.
to me, this seems backwards. What determines whether an ingredient is considered ultra-processed?
