I have Rheumatoid Arthritis and have read the Clever Guts Diet Book recently regarding gut biome and the the anti-inflammatory effect of having a healthy gut. I have been looking in to taking specifically fermented Kefir and also fermented foods such as sauerkraut (I have made my own). The company where I got my kefir from provide a booklet with the product which states that it shouldn’t be taken if you are on immuno-suppressants as it negates the purpose of the kefir, namely in boosting your immune system. (Rather like having your foot on the accelerator at the same time as the brake).
I eat a very healthy diet. Very little or no sugar, reduced carbohydrates and eating more wholegrains etc. and also to eat fermented foods. But this appears to be very conflicting advice. By eating a very healthy diet I would be boosting my immune system, but am at the same time knocking it back because I am on Methotrexate and Golimumab for my RA! I would be interested to hear what my best course of action is.
