I like all of the answers and information that you have already been given here. I have spent years doing research on gluten, food allergies, fibromyalgia, and other neurological related diseases. I have had food allergies my whole life, my mom has food allergies and so does my daughter. I have spent 8 years battling low thyroid and low adrenal output naturally. After my daughter was born 3 years ago, my symptoms increased, my allergies increased, and I was constantly in pain, had several anxiety attacks, several bouts of depression, just over all felt like poop. My Naturopath at the time suggested I try eliminating wheat and wheat gluten from my diet along with getting tested for celiac and getting retested for allergies. I tested negative to Celiac, but agreed to go on a GF diet for 30 days. Within a week I started to feel better and my GI tract felt better. At the end of 30 days I decided to stick with the GF diet.
Over the last 3 years my allergies continued to worsen and my Fibro pain continued to get worse. I switched my from Naturopath to a Integrative Health Specialist (a trained MD also trained in Holistic Medicine) for my Fibromyalgia. After trying a few different things and eliminating a few other things, we finally decided to get another allergy test done. Apparently most doctors only do the basic allergy test (the IgE) which tests only for immediate reactions. The new test I did covered the IgE, the IgA, and the IgG. And basically each ones tests for reactions over a different period of time. Found out that I am actually very allergic to wheat and gluten (mind you I had been 95% GF for over 2 years before taking the test), all dairy, and eggs. Once I removed wheat, dairy and eggs from my diet, I started to feel better.
I still have good and bad days, but I do notice immediately (like within an hour of eating) if I ate something I shouldn't have. The Fibropain comes on and my intestines feel unsettled.
So do I think there is a direct link to what you eat, how your body digests what you eat, and how your body reacts to what you eat...YES!
I really like the information given by Dr. Andrew Weil.
