The vegetable fiber that is derived from the roots of a plant called "Amorphophallus Konjak" takes the name of glucomannan; by extension this name is generally given to the entire plant. Given its remarkable healing properties, glucomannamo in Western societies is available mainly in the form of supplements that can be found in herbalist's shops. However, in East Asia - the area in which glucomannan is most widespread - the plant is mainly used in the kitchen: it is in fact cultivated with the aim of enriching the typical dishes of the local tradition and to make special tagliatelle and vegetable dishes. Amorphophallus Konjak is a plant belonging to the group of perennial herbaceous plants: it is in fact always green and can be found at any time of the year. This plant is part of the large Araceae family and is known mainly in Indonesia and Japan, the countries from which Amorphophallus Konjak comes from. In the kitchen the entire plant is used, while in herbal medicine - that branch of alternative medicine that uses the medicinal properties of flowers, plants and fruits to treat more or less serious pathologies - the root and the glucomannan are used. Amorphophallus Konjak is a plant with a very particular appearance that over time evolves in a completely unexpected way: initially it looks like a thick and rather heavy tuber; its dimensions, in fact, are those of a grapefruit. The flowering takes place in the months of April-May and is accompanied by a smell that recalls the decaying meat. However, within a month the flower withers and a leaf grows in its place. Only at this point in its growth, Amorphophallus Konjak begins to develop its roots, the part of the plant from which the fiber of glucomannan is extracted, characterized by a very light odor and a strong taste. The root of the Amorphophallus Konjak is also called Koniak: it consists of 64% glutamate, a white powder.

How to grow glucomannan

The Amorphophallus Konjak, the plant from which glucomannan is obtained, is usually planted in the months of March, April or May, therefore at the beginning of spring. It is very important to sow leaving some space between one seed and another, since once it has grown, the plant must have enough space to develop its roots. Amorphophallus Konjak needs a lot of water, especially after flowering, when it starts to develop roots: it should be planted in always damp soils, better if enriched with natural nutrients, and it should be watered regularly. This plant does not particularly need sunlight, but likes it; it tolerates both heat and cold well, provided they are not excessive. Only in a second phase, when the flower is now wilted, can the plant be moved to a drier and more protected environment.

The beneficial properties of glucomannan

Thanks to some of its special characteristics, glucomannan is particularly suitable for those on a diet, to the point of being used as a dietary supplement by many people who follow low-calorie diets and want a guaranteed weight loss by suffering as little hunger as possible. And the action of glucomannan is precisely to reduce appetite, thus limiting the amount of calories ingested per meal. This is possible because this vegetable fiber, in addition to being extremely viscous, once swallowed swells, increasing its volume by almost sixty times: thus doing it fills the stomach, stimulates the perception of satiety and consequently reduces hunger considerably. Furthermore, glucomammane is easily dissolved in water or other beverages, and for this reason it is very practical to be synthesized in herbal preparations and to be used. This fiber is made up almost entirely of sugars (especially mannose and glucose) which, however, the human body does not assimilate: this means that the organism's blood sugar levels remain constant, an extremely important characteristic for those suffering from diabetes. Not only: in addition to reducing hunger, glucomannan prevents the body from metabolizing - therefore assimilating - fats; in fact, they become trapped in the fiber and expelled with the faeces. Its weight loss function is therefore extremely valuable, as is its ability to prevent colon cancer. Glucomannan, in fact, traps and eliminates toxic substances, potentially carcinogenic, which we ingest with food. Finally, some studies highlight the ability of this fiber to regulate intestinal functions, particularly helping the lazy intestine.

How to use glucomannan

Glucomannan is therefore used as a food supplement and can be found in herbalists and pharmacies in the form of tablets or powder to be diluted in water, either alone or in combination with substances having a similar effect. The tablets contain titrated dry extract of glucomannan: their use is subject to the approval of the doctor, who will advise them also prescribe the most suitable dosage. Generally they are taken from three to six tablets a day, each of which contains 500 grams of dry extract; to carry out their anti-hunger effect, the capsules must be taken before each meal. However, this is not its only use: as a viscous, almost rubbery substance, it is also used in the food industry and more properly as a confectionery. It can be found in some types of candy, in some drinks and in ready meals such as soups, frozen sauces and many other products. Here glucomannan is used mainly as a thickener or emulsifier.
