<<Disclaimer: Verify this information before applying it to your situation.>> I note that both Hydrolyzed Plant Protein (HPP) and Hydrolyzed Vegetable Protein (HVP) are verboten to celiacs. Does anyone know if this is just because it doesn't specify which plants or veggies it originates from? In other words are, for instance, Hydrolyzed soy protein and/or Hydrolyzed corn protein safe for us? -vance
