WHY TEST IGG SENSITIVITIES?
Immunoglobulin G (IgG) food testing is a useful guide for structuring elimination diets for patients with many chronic conditions. Individuals with neurological, gastrointestinal, movement, and behavioral disorders often suffer from IgG food sensitivities. People may continue to eat offending foods unaware of their potential adverse effects. Symptoms associated with food sensitivities may occur hours or days after the offending food was eaten because IgG food antibodies remain for a much longer time than IgE antibodies. IgE food allergy causes the release of histamine, producing an immediate hypersensitivity reaction. In contrast, IgG food sensitivity is triggered by the binding of complement to IgG food antigen complexes, causing an inflammatory response. This is a delayed hypersensitivity reaction in which symptoms appear anywhere from hours to days after eating the offending food. Elimination of IgG-positive foods may improve symptoms of irritable bowel syndrome, autism, AD(H)D, cystic fibrosis, rheumatoid arthritis, and epilepsy, according to numerous clinical studies.
Many stool tests use quantitative polymerase chain reaction (qPCR) or metatranscriptomics using RNA, rather than DNA. These methods can miss up to 50% of the microbes present in a stool sample and doesn't offer information dysbiotic ratios.
A rotated diet is KEY to reducing negative responses to foods. It reduces inflammation, toxic load, hidden food sensitivities, and the prevention of developing additional sensitivities.
