Konjac
The short version
Glucomannan from the konjac corm — a powerful thickener and the gelling agent in shirataki noodles. Choking hazard in jelly minicups.
It's permitted and generally considered safe, but there are a few reasons to be mindful — like sensitivities in some people, debated studies, or intake limits. The Safety section below explains the specifics.
Safety profile
ADI not specified — considered safe as a soluble fiber when consumed in solution. The critical safety concern is texture: konjac jelly minicups (small pop-out cups) caused fatal choking incidents in children and were banned in the EU, US, Canada, and Australia. Consumed in liquid or paste form (noodles, drinks), no choking concern; soluble fiber may contribute to gut motility changes at high intake.
