Konjac, also known as Amorphophallus konjac, is a root vegetable native to Asia. It has gained popularity in recent years due to its low-calorie, low-carbohydrate nature and potential health benefits. However, when it comes to nutritional value, the answer may not be as straightforward as some might expect.
The Basics of Konjac

Glucomannan is a polysaccharide that can absorb significant amounts of water, forming a gel-like substance in the digestive system. This characteristic is what makes konjac a popular ingredient in various food products such as noodles, supplements, and even vegan alternatives.
