I don’t want to scare you, but, I was very enthusiastic to try shirataki until I read that someone ate them, felt like shit since he/she couldn’t digest them at all and it ended up with him/her throwing them up, whole and completely undigested.
That made me think it would basically be like eating strings – no nutrition and impossible to digest. But maybe this was just one scary story out of a houndred more optimistic. Like I’ve seen Able write on here: If it doesn’t benefit your health, don’t eat it.
They’re pretty much just water. I’ve had the stuff they’re made from (kon’nyaku). The fibre is indigestible because it’s prebiotic, i.e. it’ll be fermented in the colon. Maybe that guy threw up because they don’t taste particularly good 🙂
