This is caused by an abnormal immune system reaction that occurs in people that are genetically predisposed to this disease‚ researchers have found a link to this immune system reaction in

Metabolites through the body Food that we consume is composed of very complex molecules. During the digestive process these compounds are broken down into smaller and smaller subunits in preparation for use by the body as building blocks needed for the many components of the human body.
