Several factors combined together to cause me years of spaciness and difficulty concentrating. Highlights of this period included giving the wrong last name when called on in class and almost getting my head wedged between two floors of a department store while riding the escalator. Most of the causes were ferreted out after I went gluten-free, and now I can face a big project and a tight deadline without sweating it too much, given enough Pepsi.
The problem is that metabolizing an acre’s worth of high-fructose corn syrup when you’re 25 is one thing; now it’s quite another. I’m still looking for the final pieces to this puzzle.
The main causes were:
1. and 2. High histamine, caused at least in part by low iodine
I discovered this by accident when I was working day and night on a project while playing host to a cold. Out of desperation I started mainlining vitamin C — something like 1,000 mg an hour, all day. After two days of that I realized I was thinking a lot better than normal. After some research I discovered that vitamin C lowers histamine; that in some people histamine is too high all the time, and not always with allergy-like symptoms; and that histamine occurs naturally in food, some much more so than others. Now I finally had part of the answer as to why certain foods had recently started making me spacey: eggs, rice, large amounts of protein, kimchee.
The second part of the question was why I had it now, when I hadn’t before. An uncorrected, and thus steadily worsening, iodine deficiency would explain it. According to some experts, it is rampant now that we avoid (iodized) salt. Insufficient iodine will cause a rise in histidine, which the body converts into histamine.
Another theory is that I’m not making enough of a certain enzyme, amylase, that breaks down carbs. Which with a recovering celiac’s innards wouldn’t be surprising.
3. Leaky gut
A classic celiac legacy. A damaged gut can cause dairy to be only partially broken down, and it so happens that some of those only-partially-broken-down particles happen to be in the form of opioids, as in opium, which then escape into the bloodstream and make you loopy.
4. Iron deficiency
Common enough among all women, never mind celiacs. For various reasons though, it was never possible for me to get my levels up to ideal numbers.
5. Folate deficiency
Folic acid, a type of folate supplement, never did much for me so I never investigated it very far. When I learned that it’s not a very efficient form of folate, I tried the superior form (methylfolate) and discovered that large doses made a noticeable difference in my ability to concentrate. However, at a certain amount — which sadly is also the amount that makes my fingernails look REALLY GOOD —
it then raises histamine, which leaves me back where I started it made me really spacey, which felt like elevated histamine. I am not clear on what that was — my understanding is that unmethylated folic acid can raise your histamine if you’re a poor methylator, but that methylfolate would not. I really don’t know.
6. SAD, which is probably vitamin D deficiency
If I don’t use my high-intensity lamp in the fall and winter, I turn into a zombie and eat everything in sight. And stop sleeping. And think thoughts that make me look around for Hank Williams.
7. Insufficient essential fatty acids (EFAs)
These helped for about a year, then made my insomnia worse. Now they give me scary headaches AND total insomnia.
Other suspects I’ve looked at in my brain fog investigation were candida, digestive enzymes, vitamin B12, zinc, and calcium and magnesium. The latter two, once I got levels up to normal, reduced jitteriness and listlessness, which made it easier to concentrate. The rest did not seem to be involved. YMMV.
