I'm just wondering if anyone has heard of this or has any experience of it? I was diagnosed with Rheumatoid Arthritis in feb, finally, but I've been unwell and in a lot of pain since July, so going on nearly 10 months now and I've got my first NHS hospital appointment next week (I had to go to Benenden to get my diagnosis). In the interim I've been reading up a lot to see if I can ease my symptoms through diet and I came across a whole load of stuff by various RA Consultants online who were talking about the theory that Leaky Gut could be a cause of RA and other autoimmune diseases. In a nutshell the theory is that after years of eating gluten/sugar/caffiene/alcohol and dairy your gut can eventually become porous, leading to particles getting into your blood stream which then triggers an immune response where your body basically attacks itself? Has anybody else heard of this? The theory is that you could ease your symptoms by removing the list of foods above from your diet thereby giving your gut a chance to heal itself. It would be good to hear what others think about this. And fyi I had a terrible diet coke addiction for about 10 years, really bad, and now I'm wondering if I brought this Rheumatoid Arthritis upon myself.
