I have that book. I have not eaten gluten for about three years. That and carbs are important to watch.

My favorite book it 'Minding my Mitochondria.'

How has that helped, and to what degree? Thanks.

Keeping carbs to the healthful kind and simple carbs to a minimum has helped me heal. Important to do for nerves and whole body. Blood sugar needs to be kept level without spikes and lows.

That and the supplements, infrared dome etc. are all important.

Is being gluten intolerant or celiac start from childhood/younger years (but not manifest symptoms until later in life) OR can they develop even during adulthood?

I believe it can be acquired. I read a paper from 1999 once suggesting use of NSAIDs could contribute to acquired gluten intolerance. But this is still just a theory.

Cox-2 cytokines work in the GI tract to block absorption of undesirable substances ...and when suppressed by NSAIDs this can lead to "leaky gut" .

Mrs.D,
Thank you so much for your quick reply.

I threw the question because this gluten intolerance/celiac is still hanging over my shoulder. Although, my panel is negative but i become paranoid in looking for a reason for some of my symptoms. I was a pleasant and cheery person but now my mood swings. I think i have anxieties, brain fogginess. But then all these can be caused by a chronic illness. So, I am not sure where these mood swings and anxieties are coming from.

I tried a couple of times to go on gluten free but i tend to cheat because of lack of a black and white diagnosis. I know this is not a right attitude but with my losing weight, elevation of sugar, GI problem, lung issue, I could not focus on one thing.

Idiopathic-you sound like me a little. I have tried, but never commit, because I don't have a diagnosis yet for my PN.
Also, had the blood test done for Celiac and it was negative, but some will argue that the only true way to test is from a biopsy of the tissue itself. We just can't trust these blood tests in general, can we! Everyone you ask has a different answer !! B12 in particular has many variables, like the ranges considered normal, and intrinsic factor,

Anyway, I think for anyone with idiopathic p.n, it is always worth a shot to cut out gluten for as long as possible, then re introduce and note any symptoms.

Another thing I wanted to ask is if you have ever considered candida ? This is yeast overgrowth. A quick Google search will explain , if you're not familiar. The possible symptoms go on and on. You mentioned brain fog, mood swings and anxiety. I remember these in particular from working at a health food store for years.

Food for thought :-)
