Mark, totally agree with you listening to your body is the most important thing. I'm gonna check out the metabolic typing, my consultants and doc's have always suggested that high fibre things (veggies etc)are the way to go but these are a complete nightmare for me, so I could be a protien type like your dad, meat never really causes a problem for me (unless it's covered in a veggie based sauce of course!). Thanks again for the info :-)

Donald - My consultant did mention something about a new type of medication that has been successful but I thought it was in the US. Something to
do with treating and removing a type of bacteria in the gut. I think some research has shown that this type of bacteria is present in everyone and is one of the "healthy" ones but in some people it creates an immune system response which causes the inflammation. As mentioned before no-one can say why one person reacts and another doesn't. Don't know if thats the one your friend had heard about.
I have also read about trials of thalidomide to treat Crohn's.
I'd be interested to hear of any other info.
