Auto-immune wackiness runs in my family--AITD, Lupus, Alopecia Universalis, autoimmune aplastic anemia, and the gamut of allergies/sensitivities....
So, if you have this stuff, too, I feel your pain!
Anyway, READ THIS if you have AITD/Hashimoto's and you're still eating those recommended 'healthy whole grains' with gluten. Seriously, look into it. Read WHEAT BELLY by Dr. Davis, while you're at it, too.
And if you already know you're sensitive (Debbi, Deb Willbefree, etc), put down the dang gluten!!!!! Stop that!!! Ditch it!!!! Don't look back!!!! :)
Hashimoto’s often manifests as a “polyendocrine autoimmune pattern”. This means that in addition to having antibodies to thyroid tissue, it’s not uncommon for Hashimoto’s patients to have antibodies to other tissues or enzymes as well. The most common are transglutaminase (Celiac disease), the cerebellum (neurological disorders), intrinsic factor (pernicious anemia), glutamic acid decarboxylase (anxiety/panic attacks and late onset type 1 diabetes).
It's not your thyroid. It's your immune system whacking your thyroid (and, maybe, other tissues). Take care of yourself from the gut in.
And be well...
