Hi @ingekunga, I think your question is a good one and that it helps with any autoimmune condition. I have no medical training or background but what I believe has helped me with keeping my PMR in remission is changing some of my lifestyle habits - eliminating fast foods and processed foods, sugar and getting more exercise. I do have my slip ups though but I do my best to keep away from unhealthy eating habits. Here are some things that may help.
