Why are Nuts on the Autoimmune Protocol List to avoid?

Nuts are no small player in the nutrition world which is why it is somewhat surprising that they would be excluded from the AIP diet. Almost every diet anyone could possibly go on would allow the consumption of nuts but not AIP, why?Well the easy and simple answer is that nuts contain lectins and phytic acid (we talk more about lectin in our nightshade post) but with a closer look we learn that there is a bit more going on than that.
