This isn't something I've looked into but its certainly interesting. Do you have any more background as to why it interests you?
On the surface, it would appear that increasing Sex Hormone-Binding Globulin would be a bad thing for hormonal enhancers. After all, we'd like to have as much bio-available testosterone as possible, and not have it bound to SHBG.
Are any of these studies double-blind or are they all epidemiological? SHBG is affected by so many factors, like insulin levels.
Its been a while since I've read NHE, but it appears that an insulin spike from carb loading would drastically reduce SHBG levels for a while since insulin stimulates IGF-1 production, and both insulin and IGF-1 suppress SHBG.
The track record for fiber being good for anything is pretty dismal. Here's an interesting artical that Michael Eades wrote on it:

Hey all,
I have been looking into it and it seems that fiber increases SHBG,
though there may be other factors at play. Anybody have any suggestions
as to fiber intake and optimal T levels?
