Ice Cream
Eric,
Now I eat regular ice cream (when I do eat it) and I haven't had a problem with it. Early on, after my surgery, when I ate ice cream (it was rare to be honest), I got the "no sugar added" rather than the lowfat. I figured that I needed some amount of fat in my diet and at that point sugar was more of an enemy than fat. I like the Blue Bunny and Edy's brands the best.
HTH
Eric, the answer to that would be NONE. Protein shakes are not literally typical "shakes". Didn't your doc give you a packet of recipes, foods, etc? I used chocolate protein powder, skim milk, and if I wanted it thicker I blended up with some ice. Other than that it was just usually the milk and powder. I guess if you HAVE to have it, go with ice milk rather than ice cream.
