I will say 1 thing related to arthritis, and 1 thing related to broccoli.
Arthritis: I've heard CBD (Cannabidiol) is great for arthritis and similar painful medical conditions.
Broccoli: I'm not sure about helping with arthritis, although your conclusions would suggest it does help. But what I have to say is this: I'm not sure if Broccoli makes arthritis better, but it makes my flatulence worse LOL great post by the way!
That's all the fiber :)
