Why aip diet checker matters
The Paleo Autoimmune Protocol (AIP) is an elimination diet designed to reduce inflammation and heal the gut in people with autoimmune conditions. It removes grains, legumes, dairy, eggs, nuts, seeds, and nightshades during the elimination phase.
- Elimination phase removes all potentially inflammatory foods
- Focus on nutrient-dense foods: organ meats, bone broth, vegetables
- Reintroduce foods one at a time after 30-90 days
- Sleep, stress management, and movement are part of the protocol
- Work with a practitioner experienced in autoimmune protocols

What to know about seaweed
Seaweed looks like the cleanest thing on the plate and it is not. It is graded high in salicylates and high in free glutamate, moderate on histamine and moderate on nickel, which is an unusual four way stack for a vegetable. The thing it is best known for medically is iodine: kelp type seaweeds concentrate it to a degree no other food comes close to, and a single gram of dried kombu can carry more than the entire adult daily upper limit. That matters in both directions, because too much iodine and too little both push the thyroid off balance. If seaweed salad, miso with wakame or nori snacks show up in your reaction log, there are at least four separate mechanisms worth separating.
Watch for
- Iodine is the headline.Kombu and other kelps average in the low thousands of micrograms of iodine per gram dried, against an adult tolerable upper intake of 1,100 micrograms a day, so one gram can exceed the daily ceiling several times over. Nori sits far lower, wakame in between
- Graded high in free glutamate, and for good reason: kombu is the food glutamate was first isolated from, and dashi broth works because of it.If MSG style reactions such as head pressure or flushing are on your list, seaweed broth belongs in the same bucket as added MSG
- Graded high in salicylates, which puts it out of bounds on a strict salicylate elimination even though it reads as a plain green vegetable
- Moderate histamine and moderate nickel.Seaweed is grown in seawater and takes up trace metals with it, which makes it a repeat offender in systemic nickel allergy, and the dried and fermented forms lift the amine load further
- Hijiki is a special case: several national food agencies including the UK, Australia, New Zealand and Canada advise avoiding it because of inorganic arsenic levels, a chemical issue separate from every trigger above.Salted seaweed snacks also carry a lot of sodium
