Sometimes, due to certain conditions like stress, infections, mycosis, environmental poison, etc, the integrity of the intestinal wall is compromised which causes some foods to trigger an immune response as a result of which our immune system starts to produce specific IgG antibodies against them. These antibodies may cause delayed symptoms of inflammatory reactions which may lead to various chronic complaints. Such food sensitivity is called Type III food allergy with delayed symptoms. Even if you are eating healthy foods, type III food allergies can trigger low-grade inflammation which underlies many health problems such as migraine, irritable bowel syndrome (IBS), crohn’s disease, excess weight, skin problems and more.
