There are several other foods unrelated to this article that are known to cause inflammatory response including Gluten, which comes from wheat and other grains.
Since you mentioned that a low-carb diet seemed to help, maybe it is the gluten you are avoiding. Some people are sensative to it, and it even causes problems with people who aren’t but have preexisting arthritis etc. I know they had my mom avoid gluten and a few other things like sugar to help her knee arthritis pain.
I actually thought gluten early on (since avoiding carbs meant avoiding wheat) but the test didn’t show anything. I also wondered about yeast which I also don’t eat on a low carb diet. I think when summer is over (traveling etc done) I’m going to try adding things back one and a time and see if I can pinpoint something.
Until then—pass the steak!
