This substance is still little known, so the questions that arise when it comes to this topic are many:

  • The glucomannan works?
  • What is it for?
  • Makes you lose weight?
  • What are the contraindications?

On this page we will give you all the useful information onglucomannanstarting from what it is and what it is used for.

We had already talked about theglucomannanin the article dedicated to flours without carbohydrates or better, to alternative flours without friends or carbohydrates derived from wheat. Today we will talk to you about the use of theglucomannan in tabletsor in the form of pasta, products marketed forlose weight.

Glucomannan: what it is

Theglucomannanit's awater-soluble polysaccharide. To make you better understand what it is, wanting to simplify, I will tell you that it is a type of carbohydrate with a high molecular weight and that, in nutritional terms, it has a low calorie intake.

Now you will understand immediately that if the pasta provides carbohydrates (extracted from durum wheat flour) it is also possible to produce pasta based on glucomannan (extracted from the root of the konak plant).

Theglucomannanin fact, it is a polysaccharide that is produced starting from the root of the plantAmorphophallus konjak: its structure makes it perfect for those who want to lose weight.

The carbohydrates that we take with ordinary pasta or rice are starches. Starch is a polysaccharide with a high glycemic index and consists of polymerized chains of glucose.

Theglucomannaninstead, it is a polysaccharide composed of several simple carbohydrates, in particular mannose and glucose. Its branched structure makes it highly viscous and like any other fiber, it allows it to absorb a lot of water, lowering the risk of constipation.

Glucomannan: what it is for

Thanks to its properties (low caloric intake, ability to absorb liquids ...) theglucomannanit is widely used in weight loss diets.

Theglucomannan tabletsthey are very controversial as they are marketed in order to counter cholesterol levels and fight obesity. Theglucosamane tabletsare considered food supplements, the sale is free, however it is important to emphasize that the FDA has not approved glucosamane tablets for the treatment of obesity, cholesterol, constipation, diabetes or more generally for the loss of weight.

What is it for?
While some need it as a dietary supplement for weight loss, the food industry has always used it as an additive, emulsifier and thickener. It is indicated among the ingredients with the initialsE425.

Does glucomannan work? Does it make you lose weight?

Undoubtedly a dish ofglucomannan pastemakes you ingest fewer calories than a traditional pasta dish. With a lower calorie intake, any pasta substitute would be able to make you lose weight! So yes, in these terms it works.

But what about the tablets?
In commerce they are found glucomannan tablets apt to trigger a sense of satiety in order to make you ingest fewer calories. In blogs and even on wikipedia we read that glucomannan "captures fat", this is very unlikely or in any case this mechanism of operation has not been highlighted.

Also on wikipedia and in many blogs we read that "glucosamane creates a viscous mixture that would take up space in the stomach causing a long-term sense of satiety".

Nothing could be more false: glucosamane, once it reaches the stomach, is processed like any complex carbohydrate. It is the acidic environment of the stomach that initiates the digestion of this dietary fiber!

The statement that theglucomannanwould create a "gel when mixed with water" is quite misleading because even when you drink plain water it takes up volume in your stomach and slightly slows digestion. So, no, in these termsdoes not work: even drinking plain water you would feel full after eating any food.

In summary: it makes you lose weight when kojak pasta (glucosamane paste) is used in place of traditional pasta to lower the level of calories. It does not make you lose weight when taken in tablets because there is no scientific proof that this ingredient can actually create a sort of gel in the stomach!

Glucomannan: contraindications

Although the Italian Ministry of Health still does not speak about it, other countries have issued warnings on this ingredient. We have already talked about the FDA alert. Even Heath Canada has published a warning stating that the use of glucosamane tablets can only be considered "safe" for health if accompanied by a lot of water.

If you're going to take the glucosamane tablet for weight loss, be sure to drink plenty of water, even more than the manufacturer recommends.

Glucomannan paste

Thereglucomannan pasteor pasta konjakit can be an excellent alternative to the classic wheat pasta we are used to. It has a very low calorie intake and, with the right condiments, you can also eat with pleasure!

In this context, theglucomannancan be a good ally forlose weightand yes, if integrated into a proper diet, it works.

Where to buy it?If glucomannan tablets are now everywhere, it is more difficult for pasta. Among the many online promotions, I would like to point out a package of assorted packs which includes:

  • 1 package of kojac rice (glucomannan rice)
  • 5 packs of Noodles type spaghetti
  • 4 packs of traditional spaghetti

Each package is 200 gr, for a total of 2 kg of konjac pasta. On Amazon, these products are offered at a price of 21.99 euros with free shipping costs. For all the information, I refer you to the official Amazon page: assortment pack.

Please note: this is onegluten-free pasta, also suitable for those suffering from celiac disease.
