I would recommend that you at least temporarily avoid changing the food that you eat. Try eating the same foods for a few days because I think that doing that would help give your immune system a rest not having constant immune system challenges. The body seems to adapt better to leaky gut when the foods are NOT changed.
@ljimbo423 SIBO is caused by lack of stomach acid. Increasing the stomach acid when digesting protein should help with it. Some might find it a bit gross but spitting out all saliva while digesting protein can help a lot. It allows the stomach to raise the stomach acid levels when it is not being compromised by urea from saliva. This is assuming that a urease infection is present which I believe is common to CFS.
I wish I could of got a lactulose/mannitol permeability test. I did ask my doctor but she gave me some bullshit about it not being used any more. Translation "I do not want to have to pay for such a test" NHS GP.
I bet my results would be far worse than yours. However I have no intention of paying for what I already know. It would of been nice to do a comparison but not if I have to pay for it as I can spend the money better than wasting it on a test which will not really help me.
BTW if you look in your iris at the top, use a mirror and a low powered magnifying glass if you have one, x3 might be useable, I have a x5 mag which works but is right on top of my eyeball if I use it. Place the magnifying glass against a mirror and take a look. Look for a black mark which comes from the pupil and goes out towards the top of the iris at 12 o clock most likely in the right iris. These are called Radii Solaris and represent leaky gut and only show signs in extreme cases. They only show when the infection is considerable. BTW 12 o clock is the hypothalamus and pituitary. I have 5 of these marks in my irises. I destroyed most of the largest marking late last year using reduced Colloidal Silver. Ionic silver had zero effect but reduced CS gave a feeling in the right side of my stomach. I have experienced similar feelings in my stomach when taking essential oils in the past but this was far greater and far more effective. It's the marking at 12 o clock which has the greatest effect though and until I can destroy that there will only be minor improvement.

If you look at the iris chart, notice the connection between the stomach and the transverse colon at the top of the iris! IBS and stomach are connected by these infections. Where these infections attack and their influence on the nervous system, influences the function of the colon. This is why IBS can be so common when there is a stomach infection.
I will see if I can post a picture of my before and after irises at some point when I get some time. I do have an iris photo taken back in 1993/1994 by an iridologist which I can scan. It's a bit highly magnified but the important markings are visible. It's taking a current picture which I have to work out. Focussing at close up could be difficult without the correct equipment.
