you will probably find the answer to her eating habits buy remembering what
she was like as a child

was there a struggle?
was she breast fed?--was it cut short or prolonged?
did she mess with her food--spit it out
etc etc
there are stages of human development which are almost cannabalistic-- oral
stage where children put everything in their mouth Iwant to devour our
love--i want you to be part of me etc

fwiw
