I can come back and post a few links for you. What made them decide to look into grains and bipolar I think was the results of schizophrenia and glutenous grains, and two.... reasearch that showed high correlation between bipolars and bovine casein antibodies. That's the gist I got from what I read, I'm sure that this has been looked into often. They have seen higher anti-gluten antibodies in a significant amount of bipolar patients. And an increase in anti- gluten antibodies in manic patients. As well as up to half the bipolars tested against a control group, half the bipolar patients had the genes the predispose you to Celiac Disease.

Honestly I could not find a lot of research into this. Three studies that I could find, but what they did find was rather interesting. I think they need to do more research into this. One thing that I do think is sad, is that there isn't a ton of research into this, and I fear there won't be anytime soon, as cutting out food from your diet doesn't take a prescription and it's quite profitable for pharma companies. I know that's a bit pessimistic of me, but I think it's a real concern.

I'm in the process of removing gluten right now because my Dr. Suspects Celiac. I have a lot of physical health symptoms. But I am very curious how this will affect my mental health as well.

I'm not sure that it's all grains, the articles I have read pointed to grains that contain gluten. that's quite a few grains tho. Not to mention they add gluten in different forms to almost anything you can think of.
