I, too, worry about becoming sensitized to soy. If it weren't for soy I don't know what I would eat. I've read about people who can only eat rice!
But that's off subject. I am extremely sensitive to dairy protein and have never had a problem with Silk. I also noticed that they say lactose free
but not dairy free. Still... If there were any cross contamination I would know with one of my incredible headaches.
