It is a hospital menu, it's not going to be perfect.... there are people starving in this world, people in war torn dumps that would be happy to see any of the food on that menu. There are some things on it I'd eat and some I'd not, purely my personal choice. We are pretty lucky to be able to pick and choose what we want in this world. There are many who do not have that luxury.
It could be improved upon, obviously, but diet guidelines for diabetics are set by health care professionals as far as I know. And I doubt they have diabetes, maybe that is the problem. Having cystic fibrosis, I've spent plenty of time in hospital and used the cafeteria whenever possible or had food brought in. Where there is a will, there is a way.
