My comments only relate to this particular case as i have been following it with interest and is not meant to be a treatise on Diet in Human Disease.
I assume that Mic has no difficulties in swallowing and that his "pressure sores" are not the size if dinner plates oozing with fluid all over his dressings and sheets of his bed.
Fat diet:
There seems little point in having a high fat diet AND taking Simvastin and i think that it is a matter of the left hand not knowing what the right hand is doing...the medical staff not knowing she will be on a high fat diet and the Dietician not realising that he is on Simvastin.
This is no big deal and i would continue as such, with Fried eggs and bacon, Fish and chips, cheese and milk whenever he wants them.
Protein....I am presuming that he is not taking Complan or such but just needs a high protein diet. No, it is very difficult, particularly in Mic's case to take too much protein and providing that he has carbohydrates at his beck and call, then over dosing with protein will not be an issue.
I would have thought that he will have District Nurse back up and the advice of a Dietician.
If i haven't answered your question, please get back.
