What ingredients do Bernaise sauce and fruit smoothies have in common?
Bernaise = butter, egg, vinegar (usually white wine), salt, pepper, and herbs.  It would surprise me if any of those things were in your smoothie. So, based on the information you provided, I would say they have nothing in common. Beyond that, you would have to go the the Smoothie King, and the steak house, and ask for a list of ingredients to see if there is something out of the ordinary in their recipes.  Maybe you should just go see your physician.
