I'm trying to understand what anti-inflammatory foods are well-supported by evidence. I saw the old Multiple Sclerosis Diet book by Dr Roy Swank, which says to eliminate oils, dairy, processed and red meats, etc. I also just found this review from a couple years ago by Yasmine Abushukur and Rebecca Knackstedt (respectively from the Beaumont School of Medicine and the Cleveland Clinic) that says supplements of curcumin (turmeric), vitamin E, vitamin B12, melatonin, alpha-lipoic acid (ALA), and CDP choline can help recover peripheral nerve injury (https://doi.org/10.7759%2Fcureus.25135). I'm already getting turmeric and other gingers in my diet. My issue isn't an injury, but an autoimmune disorder, so I wonder what could help.

As for caffeine, @mistyisle44, do you know of a study that has shown the reducing caffeine helps? I found this 2016 paper by Brian Cairns (https://doi.org/10.1586/14737175.2016.1157471) that says that although caffeine can be associated with pain, reducing caffeine doesn't always reduce pain. I've switched to one cup of half-caff coffee per day, which seems to help with anxiety, but I don't notice any improvement in my nerves.
