Allergies can be a source of chronic inflammation for a variety of reasons. Foods can cause delayed allergic reactions or sensitivity reactions. Delayed reactions cause symptoms which onset between 8 hours and 3 days after ingestion. They set in motion an immune cascade that causes tissue damage. The symptoms from these type of reactions can vary widely from one person to another. Conditions as varied as arthritis, ulcerative colitis, migraine headaches, or chronic sinus infections may be caused or aggravated by food sensitivities.
Many people have inherited or environmentally acquired reactions to gluten containing grains or dairy casein or lactose.
Both immediate and delayed type antibodies can be tested in blood. The information from this testing can be used to change exposures and reduce allergic reactions. This calms the immune system and ramps down inflammation in the body as a whole.
