I doubt it was personal Retro. I agree with you that when you post in 50+ it is to address this crowd rather than others. In general I would argue that pretty much any health or nutrition topic is relevant to us aging riders and thus appropriate. But to make sure, you should probably explicitly draw such a connection in the originating post. When I saw the wheat thread moved I immediately guessed that mods saw some of the posts heading off toward diet religion land and figured let's just move it before it blows up. Since no one mentioned any connection to riding I can see where worried mods figured better safe than sorry.
