Hmmm. Doesn't seem to be the case with me. I'm a registered dietitian and my diet is full of "superfoods" and daily turmeric and I only had a very mild case of PMR with no blood markers. I try to eat a Pegan diet, but I do include oats and a tiny bit of processed food each day. I just recently weaned off of a 2 mg. dose of Prednisone after about 6 months. I had kidney stones about 20 years ago, but since then my diet has improved and I drink more water. Water and a little wine is all I drink. My diet is full of carbohydrates, but very little processed carbs. When I eat sweet potatoes or potatoes, I always eat the skin to keep my blood glucose from spiking. Fiber is an essential nutrient--probably the most important. It feeds your gut microbiome and that this where 70% of your immunity takes place.
