Good to know, thanks. I'm already off all oats but I do eat organic gluten-free bread, rice, quinoa and must admit, I have a sweet tooth (I love dark chocolate and sometimes indulge in gluten-free cake!). I would say that my diet is mostly organic wholefoods but by no means 100% and I consume grains, including organic corn and small amounts of soy (e.g. in chocolate or tamari). I also have not tried going off nightshades (as I've seen mentioned here by many).
In truth, I would recommend you go off ALL processed foods and grains and eat a diet of only whole foods that you can be sure are 100% gluten-free. In particular, strictly eliminate corn as if it were a gluten grain as it's starting to look like corn can be a problem for some celiacs. I assume you're not eating gluten-free oats? Quite a few celiacs react to oats as a gluten grain. A strict elimination tends to be more useful/accurate than fecal testing.
The reason that I haven't yet got stricter with my diet is that there are days (sometimes even a week or so) when I am not having these episodes, whilst consuming organic almond milk, brown rice... But perhaps I am experiencing a delayed reaction?
Also, I did try an elimination diet, eating only fish and vegetables for around a week, but I couldn't get my system to 'settle' before introducing other foods. Things didn't get worse when I introduced grains (quinoa and rice). What is the idea behind eliminating all grains? Is it helpful for many celiacs?
No, I'd happily save the money... I mostly just wanted to know what my recent test results really meant. Thanks!
If you're dead-set on testing, I'd get both TTG and anti-gliadin. The anti-gliadin is prone to false positives but you might find it helpful to have as confirmation if the TTG is high.
