The konjac plant of Asia produces a starchy fiber used in many health foods of Japan. It often exists in a gelatinous form, though it also can be produced with a stiff, rubbery finish similar to Western fruit leather. Some common foods that include konjac include vegan gelatin, flour, and herbal supplements.
Konjac is typically known by more colloquial monikers. The most common is devil's tongue. The plant is also referred to as snake palm, elephant yam, and voodoo lily. In addition to Japan, the perennial plant can be found growing in China and Indonesia.
In Japan, when the plant is used in cooking, it is known as konnyaku. Konnyaku is largely tasteless. The slightly salty, grey mass is prized for its texture rather than its taste. It is typically firmer than traditional Western gelatin, and often served in the form of thin strips or a thicker, rectangular bar.
Many signature Japanese cuisine dishes and snacks contain konnyaku as an ingredient. Fruit jellies, such as lychee cups or candies, are made from the plant. Noodles, tofu alternatives, and Japanese oden all contain konjac.
Some areas have banned the sale of konjac products. Expecting a similar product to traditional gelatin, several people have underestimated the need to chew the snacks. Some have consequently fatally choked on the foods. Those who do choose to consume konjac products should remember to chew them well before swallowing.
It is also important to know that the plant is not digestible. High in fiber and nearly calorie-free, it works as a natural laxative. For this reason, it is often hailed as an intestinal aid, and taken to help people regulate bowel movements. Dieters also enjoy the food, as it is known for its appetite suppressant capabilities. Diabetic patients may also be able to manage their bodies' glucose levels with the extract.
As a supplement, konjac can be taken in a variety of ways. A tasteless powder is available for those who do not wish to consume products made from the plant. It can usually be implemented into other food dishes easily. Capsules are also available. Tablets for this supplement are typically not used, as they can swell during swallowing, causing a choking hazard.
When taking this supplement, a full glass of water is usually needed. This will usually prevent the taker from choking on the capsules or powder. Some side effects can occur while taking konjac, including flatulence, diarrhea, and stomach discomfort.
