I'm not a vegetarian but I have had a type of allergy testing done called delayed reaction where you might have a reaction a couple of days later. In this instance regular allergy testing or food elimination diets don't identify them. I'm trying to tough out the pre-op and post-op liquid diet with protein shakes, etc but feel terrible. I am sensitive to milk and milk products including whey, wheat, peanuts, and eggs. The only other things I can think of to eat in liquid stage would be maybe some pureed beans or tofu shakes. Any suggestions?

If you have dairy intolerance, try the soy or hemp protein powders.

Had to laugh. I hadn't heard of hemp protein but I work in nuclear power and have security clearances and drug screens all of the time. That would be so funny to try to explain that! Thanks for the input.
