What is konjac / glucomannan?
Konjac is a plant that grows in the warm subtropical regions of East Asia and whose rhizome provides a soluble dietary fiber: glucomannan. It is also found under the names konnyaku or language of the devil. Konjak is a low calorie but high fiber plant.
Glucomannan is composed of 40% of the dry weight of the plant, and is often used as an additive in Asian cuisine for its thickening effect.
In Asia, konjac has been used for a very long time as a natural remedy and as a food.
In the West, konjac fibers have recently begun to attract attention for their supposed action on weight loss.
The konjac now has an E number (E425) ( source ). E numbers are codes for substances that can be used as food additives in the European Union.
A normal serving of konjac powder is half a teaspoon (2 g), which is equivalent to about 5 calories and 2.5 g of fiber. This dose corresponds to about 10 percent of daily fiber requirements.
