Most of us are familiar with the scary types of IgE mediated food allergies like you may have read about in articles like this one in a February 2009 edition of Time Magazine.
But scientists are starting to identify different types of immune reactions involving IgG antibodies. (Your body makes 5 classes of antibodies, IgG, IgM, IgA, IgD, IgE).
People with IgG food allergies don't break out into hives or go into shock when they ingest inappropriate foods. The symptoms can be quite varied. Headaches, irritable bowel syndrome, rheumatoid arthritis and other conditions may result. Alternately, you may actually feel fine while chaos ensues internally.
In a 2008 study, researchers stated
"We show here, that obese children have significantly higher IgG antibody values directed against food antigens than normal weight children. Anti- food IgG antibodies are tightly associated with low grade systemic inflammation.... These findings raise the possibility, that anti-food IgG is pathogenetically involved in the development of obesity and atherosclerosis."
The jury is still out on IgG food allergies. Some clinicians dismiss them as irrelevant because we don't know enough about them. But the research is trending toward the recommendation that doctors identify and manage IgG food allergies.
This may be a key component in your chronic low grade inflammation and obesity.
