I contacted nuts.com and they responded with: They are not shared on processed lines or contaminants. They are on an exclusively gluten free line.

I am following the COMB study as documented in the NIH PubMed web site. This involves calcium, magnesium, strontium,  DHA, vitamin D, and vitamin K2-MK7. If I don't consume the nutrients in my diet I take supplements.  My second bone density test showed significant improvement without taking drugs as my GI doc predicted. My case is several standard deviations from normal, so common medical advice for osteoporosis doesn't apply.

Nuts.com has a different label for gluten-free (gluten-free in a circle), and one for GFFP certified (GFFP icon). Which one was on your package of nuts?

Until I was 19 years old, docs told me I was anemic and to take iron. I had the same side effects from the iron that you describe, felt awful. Then when I was in college, I had a really bad reaction and it took a medical student to actually give me iron and retest within 30 days to find that the iron was not improving my anemia at all.  He found out that I had thalassemia minor, a genetic blood disorder that is not due to iron deficiency.  It's also called Cooley's Anemia or Mediterranean Anemia, not uncommon in people with ancestry around the Mediterranean, southern Asia, and into Africa. Since iron is not water soluble, taking more iron than the body uses can build up in organs, like the liver, and cause problems years later. I don't mean to alarm you, but please make sure she is getting retested to make sure the iron is actually helping her anemia and there's not some other cause.

We decided along with the pediatrician based on his results and his sister having it that he does have it and proceeded with the gluten free diet. His behavior seems a little different so we will see how things change over the next few weeks! We think we just caught it really early.    He can always do a gluten challenge when he's older if he wants to, but my hunch is that when he eats it on accident we will find out pretty quickly!
