Whole Foods
I pick up my Think Thin protein bars from there but it may be a while before you can tolerate protein bars. However, gluten free products helped me transfer from puree stage to whole food stage. I would for now look at what they have and try to keep a mental picture and as you progress you know what you may want to try. They have vitamins and several different kinds of natural protein. Again, I would at least see what they have you may need within the next few weeks. But realize after the surgery your taste will change and somethings you will not be able to tolerate anymore.
