What is konjac, its benefits, types, and risks of using it



Konjac is a plant used by manufacturers to make high-fiber nutritional supplements, jellies, and flours, and more recently in weight loss products, as well as playing a role in Japanese and Chinese traditional medicine. In this article, we will learn about konjac, its types, benefits and risks.


What is konjac?


Konjac is a Japanese root vegetable full of fiber, which has been used by people in East Asia for thousands of years and is mainly cultivated in Asian countries. Similar to the oddly shaped potato (because it comes from the same family as the potato), it also contains a soluble fiber called glucomannan. In fact, it has the highest molecular weight and consistency of any known dietary fiber. Manufacturers use this part of the plant as a dietary supplement and in the production of high-fiber flours and jellies.


There are many products for konjac, including:


Konjac Flour: Producers make this by grinding dry konjac husks to make flour. This can then be used to make pasta.Konjac jelly: After further processing, konjac flour can form a jelly. This can serve as an alternative to gelatin, which people can use as a food thickener.Soluble Konjac Fiber: Purified konjac gel converts it into a soluble fiber for use as a dietary supplement.

Konjac Benefits:


Konjac has many health benefits, and many of these benefits are related to its high content of glucomannan, which is a soluble dietary fiber that is naturally found in the konjac plant.


1. Diabetes Control:


Research suggests that taking a combination of glucomannan and American ginseng can improve the control of type 2 diabetes (insulin resistance).

A 2015 study also found that glucomannan made diabetics less likely to eat foods that can increase blood sugar levels. This is because it made them feel fuller for longer.

As konjac contains glucomannan, it is a great agent to help control sugar levels in the body, and thus helps control diabetes and its symptoms.


2. Weight control:


The glucomannan from konjac may be beneficial for people looking to lose weight. A 2005 study found that a soluble dietary fiber supplement helped overweight people reduce body weight. The participants took the supplement as part of a balanced, calorie-controlled diet.


Glucomannan might help a person feel fuller for longer by slowing the rate at which the digestive system empties. Moreover, konjac weight loss supplements aid weight loss, as they help suppress appetite and increase weight loss.

It was found that the best way to lose weight from konjac is to eat foods that contain konjac as the main ingredient. Foods such as noodles, konjac rice, and spaghetti noodles are made with konjac flour that reduce carbohydrates and therefore calories, and this is a great alternative for those who want to continue eating dishes that are usually higher in carbohydrates and calories to aid weight loss.


3. Lowering Cholesterol Levels:


High cholesterol increases a person’s risk of heart disease and stroke, and doctors recommend eating water-soluble fiber to support healthy cholesterol levels and weight control.


A 2019 study in mice found that eating konjac significantly reduced levels of cholesterol, as well as low-density lipoprotein, which is known as “bad” cholesterol. A 2017 study investigated the dose of glucomannan needed to improve cholesterol levels and found 3 grams per day to be a beneficial dose.


4. Constipation treatment:


Taking a glucomannan supplement may help regulate bowel movements and prevent constipation. A 2017 study found that taking glucomannan improved the frequency of bowel movements in children with constipation. However, the researchers also found that taking glucomannan did not always improve stool consistency, so it wouldn’t be the only treatment for


supplementation can reduce symptoms of constipation during pregnancy, as glucomannan was found to increase stool frequency and consistency.

6. Wound healing:


In addition to supporting healthy skin, glucomannan may also help the body heal wounds more quickly. A 2015 study in mice found that konjac supplementation encourages wound healing by supporting the immune system. However, more research is necessary to conclude that glucomannan has the same effect in humans.
