I just came back from the ER, having found out I have inflamed gall bladder. They told me to eat low fat diet. Do you have any suggestions as to diet, dietary supplements, any other procedure to dampen effects of, reduce future recurrence of this problem?
A low fat diet is your best bet.  Along with that you should try to be at ideal body weight. Other remedies or supplements don't usually work. If you have gallstones or have recurrent problems you may need your gall bladder removed
