AS / axSpA N=1 diet experiment tracker

Diet evidence in AS is limited and inconclusive. Use this only as an adjunct to medical care, ideally with a dietitian if the change is restrictive.

Safety rules
- Do not replace medication with diet.
- Change one thing at a time.
- Stop if the diet increases fear, restriction, weight loss, social isolation, or disordered eating.
