Not so much workout related but still health related in a way. lol

The fiber in beans is already good for regulation blood sugar and digestion. Fermenting them would seem to be adding to this impact by greatly reducing the carb load and further increasing the fiber content. Not to mention the fact fermented beans won't give you gas because those compounds get fermented out as well. Also an 8% increase in protein value is nice to boot. Downside is a loss of some vitamin content but I'll take that trade off.

I'm interested in how it would impact something you can make tofu out of like soy or garbanzo beans. I actually have some garbanzo beans fermenting so I plan to try it out. I made a tofu out of regular rehydrated garbanzo beans by blending them up into a paste. Straining out the liquid which I cooked down. I steamed the solids to cook them then added them back into the liquid once it was thickened. Made a paste that was like mashed potatoes and glue. lol. Once cooled in the fridge though it made a pretty firm and cuttable tofu that had more texture than a normal tofu. Going to try the same technique but with the fermented beans instead and see what happens. lol
