I have LOTS of experience with delayed sensitivity testing and rotation diets. I've had both ALCAT and Immunolabs several times over the past 3 years. They all initially made me feel better and then gradually over a period of 2-3 months I would start reacting to the foods I was eating even though I was rotating as prescribed. I think there were a couple of issues at play here.
First, I was not grain-free. If rice and corn were okay on the test, I would eat rice and corn. What I understand now is that by doing so I was continuing to aggravate the leaky gut rather than help it heal. Google “zonulin” to get a better understanding of the cause of leaky gut. Zonulin is now believed to be the protein that regulates gut and brain permeability. Gluten from ANY grain interferes with zonulin's ability to do it's job. The grains give you leaky gut in a way that the ALCAT test doesn't measure. That is why rice and corn appeared to be “okay” for you when really they're not. The ALCAT test's “positive” result for gluten is just showing that you have absorbed this protein and your body has recognized it as foreign. According to Dr. Osborne, other substances that can interfere with zonulin (independently of whether you “react” to them or not) are dairy, soy, and peanuts (actually all legumes, but peanuts are the worst offenders). So, if you are trying to heal a leaky gut, avoiding these foods, at least in the short term, would be helpful. And definitely continue to follow the True Gluten-free diet.
Second, the ALCAT and Immunolab tests are not the most reliable tests out there, but since you have had it done, go with the results. Watch out, however, for reactions to other foods. If you ever decide to be tested again, the ELISA/ACT Biotechnologies test is the one recommended by Dr. Osborne for the best accuracy.
I am beginning to think that if you are truly gluten, dairy, soy, and peanut free so that your gut can heal, and if you avoid your “sensitive” foods while your gut is healing, then there is no real reason to rotate the foods that you CAN eat (Dr. Osborne, chime in here if this thinking is faulty). If you find that your gut is not healing despite this regime, then there are other things out there that you can do to promote the healing of the gut (so I've been told by Dr. Osborne–I'm not sure what those things are). I've been following this protocol for about 2 months now and i'm continuing to feel immensely better – a record I never achieved on the ALCAT diet alone.
