Truth is she is 83 yrs old and stuck in her ways. She's been in this country since she was 19, but still goes to Chinese dr.s almost exclusively. If they tell her it's good, she will try it. If not... no one knows. I think at this point it is a security thing in case she can't handle the pain.
Hubs was just texting her... bone broth is the one thing she really wants. You could live a pretty good life on nothing but that. Your DD should try it. Full of collagen that coats the digestive tract and prevent all sorts of problems.
