GI Disease and requesting dietary accommodations from college

My daughter has been diagnosed with GI disease from a gastroenterologist. Basically she has to be very careful on what she eats or she gets ill in the morning. Often times even when she is careful she still gets ill. Typically she gets severe stomach pains and often times resulting in vomiting.

She has minimized this with medication and diet - she also worked with a nutritionist to help her. The long and short is there is a lot of trial and error to determine what causes this to trigger it. She has found that having smaller more frequent meals, and staying away from a lot of different types of foods.

This year she is living in a house shared with 5 other girls - it is campus housing, but it is a house with a full kitchen so one would think there is no need to be on a college meal plan. We found out it is mandatory that all students be on a meal plan because apparently these 20+ young adults are incapable of being adults and feed themselves (summary of what campus housing explained to me). We can get a medical exception.

Next medical exception is insane. We had the form filled out by her primary care doctor - they denied it saying they needed it filled by the GI specialist. He was unsure how to answer some of the specific questions - these are written for any sort of special accommodation to fulfill any sort of disability. So instead he wrote a note on letter head.

They denied it saying it wasn't specific enough. That saying that she (meaning my daughter) feels like.... is not factual - this was in reference to the reason that most of the cafeteria food makes her feel ill - there is a lot of crap that they serve - lots of processed foods so basically she would eat salad and cereal , banana when she lived in the dorm previously due to the lack of quality foods.

The thing is we are not asking them to make anything special for her - just exempt her from paying $1,000 to the school for food she will not eat. And use this $1,000 to go to the grocery store and buy fresh food that sits well for her.

Any suggestions - I tried calling and left a message explaining that this sort of disorder is not specific so it is difficult for the doctor to give specific details - it varies from person to person.

I am thinking of moving up the chain of command because this is really ridiculous - these are supposed to be adults and should be able to prepare their own food if they have a full kitchen easily accessible - what is the point of renting a house? This is one reason why she wanted to get a house on campus.
