Autoimmune Diet? in Sclero Forums (MAIN) Posted April 23, 2013 Good info! Thanks. I don't know if changing my diet would change my symptoms at all, but I can only imagine that cutting out alcohol and caffeine, both affect blood vessels, would help. Alcohol would be an easy cut but caffeine? Oy. I don't know if I am ready mentally to make a big change like cutting gluten or all sugars from my meals. I have been waiting over a month to see my rheumatologist, and that appt is next week. I will make sure to add DIET to my list of questions!!
