Fun fact. Many autoimmune issues can be triggered / worsened by diet. There is an auto immune protocol diet that is all about reducing inflammation.

Spend a few months on any of the support forms and you’ll see a pattern where people take years to be diagnosed. Most have a mystery illness for several years before it’s diagnosed.

Then they go through years of various medication options with mixed results. Eventually many end up going to diet as a solution.

Many of the various low sugar tend to be fairly close. So a lot of people dealing with autoimmune via diet without realizing it.
