It’s best to feed your gut bugs so they produce butyrate. But getting good gut bugs doing their good stuff is more difficult in the elderly, even with high fiber diet and yoghurt and all.

One should really discuss it with one’s doctor before taking the supplements. And do your own research, too, of course.

I am sure this is part of it, if not most of it. It runs (!) in parts of families, not the whole family. Which does not necessarily mean it is biological in origin.
