Darius, I have some history working with people with eating disorders. People will purge for different reasons but after repeated behaviour
of this type, it can actually cause damage. I am not sure if your mother is Indian and if so, she may be used to the spices in indian food which can be different that those wonderful salads at Panera Bread. I also like their coffee. In some cultures, people learn ways of dealing with medical issues without consulting doctors and simply use cultural norms instead. Is it possible that your mother is tied into cultural foods as well as cures?
