I bought this book for my brother, who had just been rushed into hospital with a bad attack of ulcerative colitis. During his 5 week stay in hospital, he had nothing much to do, so decided to read the book. Under normal circumstances, he would have thrown the book to one side saying "it's probably a load of rubbish". However, being in hospital made him a captive audience!
He decided to put the suggestions into practise. He made note of what he'd eaten and what reaction he had. He said the reason he implemented changes to his diet, was because the reasoning was logical. It appeared that every time he deviated from the recommendations, he took a retrograde step.
It's difficult to judge the full extent of any improvement, because he came out of hospital with 4 different kinds of tablets. The main immuno suppressants were changed from intravenous to oral, which slightly impeded his progress. He firmly believes the findings are true and regards the book as his 'bible'. Hospital food is notoriously bad, but somehow he managed to order steamed fish etc. and the staff ended up bringing him different food!! He even asked his daughter to bring in sardines - for the Omega 3. A sceptic turned advocate, over night!
I sent the book straight to him, so I haven't yet read it. I'm due to see him soon, so will read it myself.
