Autoimmune Protocol Diet (AIP)
The AIP is also known as Paleo Autoimmune Protocol because it is derived from the Paleolithic diet (which is based on meat, fish, vegetables, nuts, and seeds) (Medical News Today), although it is a stricter version, eliminating foods that may be antigenic, stimulate the immune system, or create dysbiosis. There are three phases: the initial elimination phase removes grains, legumes, nightshade vegetables, sugar, dairy, eggs, nuts, seeds, alcohol and coffee, processed foods, and industrial seed oils; the reintroduction phase, where items are individually reintroduced while monitoring for symptoms or progression of disease; and the maintenance phase, in which patients sustain their personalized restrictions and reintroductions as long as they are symptom free.
