Okay this might seem like a silly question, but I'm wondering if there are many examples of eating specific organ meats being good for that specific organ in your body. For example:
Liver: Liver appears to be one of, if not the richest source of choline. Choline is quite important to liver health and, according to Chris Masterjohn, it's deficiency is a huge driver of fatty liver disease.
Joints: Joints, which can made into bone broth/gelatin, may be good for joint health.
It makes sense in theory, that organs would contain nutrients they need for proper functioning. Anyone know of some other examples?
