Yep, agree with all of that. It’s a complex science. Nowadays, I use food testing to help people find their ‘healing diet’ and usually advise a Cyrex 3x if still on gluten because we need to find the kingpin allergen, if you like, plus a P88 or Cyrex 4 to find cross-reactive gluten foods and any with complement issues.
But, most importantly, I will advise a gut screen to check for clues to increased sensitivity – far more complex than leaky gut, note – and then work on whatever comes back which may be making the person become ever-more sensitive. It’s usually a combination of poor SIgA, SCFA and enzymes levels somewhere.
I will also consider neurological issues. For example, do we have a brain-gating problems or are neurons too close to threshold? Vascularly, is hypoxia, a lack of oxygenation a problem? Is there are really big issue at the heart of it like autoimmune gastritis?
So, yes, it’s complex and not just about food testing, but that does have a part to play. If you can find at least some of the key allergens, then you can reduce the impact on the body and encourage healing. And, if a person comes back with loads, you know it’s a loss of oral tolerance and the hunt then starts for why?!
