Thanks for your very prompt reply. Unfortunately what I did not make clear is that I cannot do any cooking. I have very compromised mobility and cannot stand for more than a few seconds. Also, my trigeminal nerve is dead, giving me a numb face, mouth and throat, and difficulty swallowing, so nuts and any hard food is out of the question. I will source some of the books, but the best I suppose I'll be able to do is to add some healthy options.
I do have porridge or muesli for breakfast!
