Amorphophallus konjac - Araceae
Properties of Konjac+Glucomannan
Glucomannan is a granular powder, which is extracted from the root of konjac. The tuber contains a fiber, soluble in water, composed of a polysaccharide with high molecular weight, consisting mainly of glucose and mannose. It has high viscosity among all the dietary fibers known and has the ability to attract a lot of water, giving rise to a soft gelatinous mass, giving the plant property slimming and satiating.
In the presence of liquid, in fact, glucomannan generates a gel, able to increase its volume about 60 times, compared to that of its dry form; then if the environment is acid reaches its maximum expansion, up to 80-100 times, producing a sense of fullness and satiety. Therefore in the stomach after 15 minutes after, the fiber begins to swell. After about 60 minutes arrives at the maximum value, thanks to the presence of gastric juices, and here it remains for about two hours, carrying out the anti-hunger.
Recent studies have confirmed that the intake of dietary fiber and a healthy diet, reduces the risk of developing heart disease and diabetes. Glucomannan, as fiber, counteracts the absorption of fats and slows that of sugars. This cholesterol-lowering and glucose-lowering properties is indicated in overweight subjects who are in a diet diet; and in the presence of sugars or triglycerides in the blood.
Finally, the soft mass, viscous, when it arrives in the colon and is not absorbed its high viscosity exerts a laxative: massages and cleans the intestinal walls, promoting the elimination of feces in a mechanical way, ie without causing peristalsis induced by stimulation .

Description of the plant
The Konjac is a perennial herb that is part of the well-known family of Araceae, which also belongs to the calla. The genus Amorphophallus consists of about 200 species, some of which are among the most spectacular flowering plants.
The plant grows from a tuber (root) that has the shape of an apple gigantic and can reach several pounds of weight. From its center emerges in the spring inflorescence, high and more than a meter and a half, it takes a few weeks to fully develop: on a stem with a diameter of 3-4 cm. engages spadix of the same diameter, dotted at the base by a large number of tiny flowers, inconspicuous, and enveloped by a kind of leaf (spathe) that widens in a cone shape in a few days, color and texture very similar to the raw meat. The smell of this "flower", which recalls the strong stench of rotting flesh, allows the plant to attract insects that pollinate the tiny flowers.
Other particularly interesting is certainly that the inflorescence emerges from the tuber, without that this can supply water and nutrients from the soil, because at this stage is still free of roots. Once wilted flower, from the same point, at the height of more than a meter long petiole and green mottled brown, it will open a single leaf jagged in the Anglo-Saxon did give the plant the name of snake palm.
The habitat of glucomannan
A native of East Asia, is widely cultivated in Japan.
The tubers of Amorphophallus of many species are eaten in their countries of origin, but after thorough cooking, because otherwise they are toxic. Glucomannan has been used in Asia for centuries in the preparation of traditional foods such as noodles and tofu.
It is currently used in vegetarian cooking and food gelled thermostable. Glucomannan, being a natural vegetable gum is also known as Konjac gum.
Generally it is used in the food industry as a gelling agent, thickener, emulsifier, stabilizer and soluble fiber source. Konjac gum has applications in many food industry products like beverages, batters for bread, candy, salad dressings, soups, sauces, and many other products packaged and frozen.
A recipe with glucomannan
Being a fiber, glucomannan may reduce the absorption of any drugs, holding them. You should then consult your doctor about your employment opportunities in the event that you need to follow chronic therapies and distanziarne intake from that of drugs.
It is essential to a high fluid intake in order to achieve the target: if not, in fact, could paradoxically be superseded by a condition of constipation
Other possible side effects (diarrhea, heaviness in the stomach) are mostly involved in the recruitment of excessive quantities. It can promote bloating and reduce the absorption of fat soluble vitamins.
2 tablets of dry of glucomannan 1 hour before main meals, with plenty of water
