Thanks guys she is currently taking ADEK and has been taking digestive enzymes since she was diagnosed at age 1. My wife and I eat high protien diets and so as a 10 year old she goes home and repeats all to her mother. Now I understand it is harder for her body to digest complex protiens we do not make her eat lots of protien we just try to have her look at what is in what she is eating before she eats it and to include as much protien as possible. She doesnt eat fish, chicken, or eggs and I am not really looking to put here on any supplements her growth is off the charts and she is doing very well. Her mother doesnt care about how she looks and I dont want my daughter to end up like that. The real issue here I guess is her mother is trying to say protien is not good for CF patients but I tend to dissagree you must have protien for growth at any stage in your life. I appreciate any help, opinions. Thanks Hardhanger
