Meme--my MIL lost her gall bladder to gall stones because she lived the no fat life. Her doc never told her just eat some fat at each meal---instead, that gall bladder needs to be removed. Unfortunately, more information is coming out that the trickle of bile into the GI cannot provide enough bile at the time fats and fat soluable vitamins arrive at that point in the gut to allow proper absorbtion of those nutrients. THis latter information, I just picked up from Dr Berg DC.
