Schizophrenia / Mental Problems and Celiac Disease

The following was written by Dr. Kalle Reichelt who is a leading celiac disease researcher at the Pediatric Research Institute in Oslo, Norway. Please direct any questions regarding this article to him at: K.L.Reichelt@rh.uio.no

What most people ignore is that both peptides and trace (biologically significant amounts) amounts of proteins are taken up across the gut mucosa (1,2). Because one molecule of gluten contains at least 15 opioid sequences it is quite clear that this could cause a problem. Increased peptide excretion is found in the urine of celiacs before treatment (3) (Reichelt et al in prep). This is confirmed by a series of papers that demonstrate intact food proteins in mothers milk (4-7). A Canadian group has confirmed that gluten does change a brain enzyme and monoamine levels in cats (8). Their findings a significant even though cats are not gluten eating animals. There is increasing evidence that components from food can indeed cause serious psychiatric (9-12) and neurological (13-16) diseases. Even rheumatoid arthritis may have a link to food proteins (17), and it well established that stress increases gut permeability. Nobody denies the possibility of reactive depression, but there is little reason why this could not be made worse by dietary factors. Because antibodies are indeed induced by peptides it may even be so that dietary peptides by mimicry to endogenous cell surface peptide sequences, may be responsible for many autoimmune diseases (18).

I feel the same. Every so often, someone will roll their eyes. I try not to discuss it unless I have to, only because I don't love having the topic of conversation become me, but others seem genuinely curious. Every so often I have a pity party over not being able to just pick up a sandwich a...

I can't remember, but it was a few years ago and maybe it had Maltodextrin in it, or maybe it was the 'flavorings' - which I never eat unless it's from a company like Kraft or McCormick that labels clearly. But given that you eat it safely, maybe I'll contact the company for a clear answer.

So the simple explanation is - You eat gluten. It travels along and gets to your small intestine. For some reason, your small intestine feels it is an invader. but instead of making antibodies that "attack" the gluten, the small intestine cells make antibodies that attack itself. Sort of misg...

Hi - I think some of the issue here may be stemming from confusion about the word "exposed" and the two things in bold above -- while you are very strict about eating gluten, am I right that you've been accidentally eating some and for the past month have accidentally been not-gluten-free? If so...

my thinking was that if I ate gluten tonight again , then the reaction would be there tomorrow not that there would be gluten for them to find exactly. So from what your saying It would make sense - i.e. if my body was going to react to gluten with antibodies then by eating gluten say tonight it ...
