I know this is a lil more extreme and Dr Greger does have an agenda of Plant based diets but he always has a decent explanation of the possible triggers.

Long-term sufferers of RA - and the people in their support networks - know first-hand that RA is a complex and progressive condition that requires some pretty hardcore medical interventions to manage. Like other auto-immune diseases, different people will experience different disease courses. A very small few will be lucky enough that their disease goes into remission for no clear reason. Others will try everything under the sun only to see their disease become worse and worse. The reality for sufferers is that there aren't quick fixes and simple triggers.
It's reasonable to expect that general lifestyle interventions such as healthier diet and the right type of exercise regime may improve symptoms within the margins permitted by the underlying disease process. But promoting content that centers the role of "lifestyle" once RA has already developed only trivializes the disease and widens the empathy gap that sufferers already face.
Now you come that this "widens the empathy gap that sufferers already face" and "trivializes the disease".
I think you are overreacting.
I'm not overreacting. There are many people who will read my comment and know exactly what I'm talking about. This is simply a "you get it or you don't" situation where you're currently on the "doesn't get it" side.
