I've looked at a few posts here about spent grain. Seems fairly common to use as an ingredient in bread and cookies. I guess one could use it for other recipes as well. But, I got to thinking last week, could spent grain be a good source as a fiber supplement? I take a fiber supplement every day. So, I thought if this were possible I could not only save a little money but also repurpose something that usually gets thrown out in the woods. I've done very little research on this subject so far, but have found articles where studies have been done and there were mentions as to its health benefits.
My question is, has anyone here at this forum ever tried to use spent grain as a fiber supplement? I suppose it would have to be well dried out and ground up quite a bit so it would be water-soluble.
Anyway, look forward to any comments you may have.
