I recommend avoiding potato chips whether they give you migraines or not. 😂

And there are lots of food sensitivies.  You just have to figure out what works for you.  I don't think medical science can tell you.  I cannot handle whole wheat - my gut dumps itself... but I can have white bread no problem so it's not a gluten thing.  In any case I gave up wheat for 3 weeks and my IBS is gone.  I've had a full week of amazing poops.  So I am definitely sensitive to wheat.  For some people it is FODMAPS but on me they make no difference.  Cabbage, beans, I handle these just fine.

I'm not even anti-Keto.  I think a 100% sardine diet is near ideal.
