Just to clarify for you - peanuts are legumes, not nuts. I actually stored this information in some tiny corner of my brain from nutrition class as a youngster - but brain fog didn't let me access it until I was educating myself about food chemistry after Celiac diagnosis.
Eliminating many food groups is tough and may not be necessary - but it can't hurt and very well may help. Not sure what your medical team will suggest, but I would not go longer than six months without trialing the removed foods individually with at least three days to a week between trials while keeping a detailed food symptom log. There are many healthy foods you may be able to reincorporate into your diet.
Exactly (peanuts are legumes, as are probably other "nuts" from the ground).
And eggs are NOT dairy (milk). They are eggs, technically a protein.
You need to educate yourself about food. You need to be able to discern if what you are reading, hearing, and doing are correct.
If someone tells you something, look it up. Does it sound reasonable? Because doctors (all types) and nutritionists toss random crap out there. Some of it is good advice, and some of it is opinion, outdated, nebulous, or just flat-out WRONG.
There are excellent resources out there for people dealing with AI issues. People who have DONE IT. Not just professionals who give advice, talk the talk, but don't walk the walk. And while professionals (MD's, MD's, nutritionists,RD's) can give excellent advice and on some days save your life, it is rare to find one who has "walked the walk".
And if more followed the advice they dished out, AI management would be light years ahead, IMO.
