Eating konjac noodles makes my stomach upset.

Konjac contains tannin, which is the kind of substance that raw persimmon causes astringency. Eating too much will upset your stomach. However, in the processing of konjac, alkali treatment is usually added to remove astringency. Whether it is tannin or alkali, eating too much at a time may cause gastrointestinal reactions in some people.

I hope to adopt.
