Gluten, the protein found in the most common grain eaten in America - wheat - as well as barley, rye, oats, spelt, triticale, and kamut, is an excellent example. Gluten is one common factor that can create so many illnesses and diseases it would be hard to count them all.
A recent review paper in the New England Journal of Medicine listed fifty-five "diseases" that can be caused by eating gluten. These include many neurological and psychiatric diseases such as anxiety, depression, schizophrenia, dementia, migraines, epilepsy, and neuropathy (nerve damage). Gluten is also linked to autism.
Besides making the brain inflamed, gluten can be broken down in the gut into odd little proteins that are almost like psychedelic drugs (opium-like peptides called gluteomorphins). These change brain function and behaviour.
Gluten also contains significant amounts of glutamate, a molecule that accelerates, activates, excites, and damages brain cells through a special brain receptor or docking station called the NMDA (N-methyl-D-aspartate) receptor. Overactivation of this receptor by glutamate is implicated in many psychiatric orders. Glutamate is called an excitotoxin (a substance which overexcites and kills or damage brain cells).

You're welcome! Those who have allergies like coeliac disease may experience an immediate reaction to gluten, but that does not mean those who don't seem to be allergic can take it without any long term consequences. I personally have reduced my gluten intake by a large amount and found my body is not as inflamed as before.
