It wouldn't surprise me at all to learn in years to come that bipolar illness is
partly caused by a severe allergy of some sort that reacts in a way that
makes it appropriate to say, in part, that it might be a "brain allergy".

Years ago, I read that bipolar patients have an extreme allergy to grains. With all the new research now on the re-engineering of grains and the problems appearing in exorphins in wheat, barley, and rye, it's quite possible that exorphins play a role in wide mood swings. Sugar certainly does, and caffeine is harmful for people who have a sensitivity to it.

Dr. William Davis confirms the exorphin problem in "Wheat Belly", but says that more research is needed to make affirmations about wheat, barley, and rye gluten (and its exorphins) in relation to ADHD and ADD illnesses.

The brain is so sensitive in bipolar illness for many of us. For those of us who are sensitive, these things are very, very important to control in our diets for feeling-well tone. I was identified years
ago as having an inherited allergy gene, and I can tell you that when I've had something I shouldn't have in my diet, I both feel it and know it within hours. You may also have that kind of sensitivity if you're bipolar.
