can you give a basic "Good food" list or "avoid foods" list?

I currently work with blind and severely handicapped children- in a school setting.In a 5 day program- school monday -friday home Fri- Sun.- Situation: 16 yr. old girl, not a lot of parental involvement, girl is known to have "Gerd", premature at birth: 1.5lbs. currently 66lbs., asmatha, will eat a half portion of school regulated breakfast, lunch and supper.

usually Mon. after breakfast ( usually consists of scrambled eggs, slice of american or motz. cheese, 8oz whole milk w/ instant breakfast) could be anywhers from 20- 1 hr. later, continued coughing which then leads to phlem being brought then followed by breakfast.

after some gravy meals( chicken pot pie, potatoes and gravy ect.) some chicken meals, I am really just starting to jot down any and all of a pattern,

she is unable to tell excatly what or where she feels discomfort or the feelings of situations, just after and episode that her stomach and head really hurt, ( with no doubt as she puts every muscle into action as she goes through these vometing episodes.)

I would like to follow up if I'm on the right path before I continue to fight on her behalf.

she is curently on nexium, but I am not sure this is her best defense product, school officals are secure with the idea that this is anirexia, I on the other hand am not convinced, as there are many days she will come to me and say she is hugry - eat something and be fine. 

a pattern of days she seems to be very tired, drawn out, fatiqued it seems.

I will try to answer any questions that you may have- but please understand I am searching for answers, with not alot of back up (parent really does not feel theirs an issue-says shes fine at home)
