Konjac Glucomannan

What Is Konjac Glucomannan

Konjac Glucomannan (KGM), also known as glucomannan, is the main component of Konjac. Konjac glucomannan is extracted from the tuber of konjac. It is a kind of natural plant neutral polysaccharide formed by the polymerization of glucose and mannose through the β-1, 4-glucoside bond. Glucomannan is a kind of high molecular weight, non-ionic water-soluble polysaccharide. It is also a natural polymer polysaccharide with the highest viscosity among known plant polysaccharides. It can form a high viscosity solution in water, which is similar to galactomannan. Glucomannan is a commonly used food additive used as an emulsifier, stabilizer and thickener. In addition, due to its fiber characteristics, it is used by some people as a nutritional supplement for constipation, acne, obesity and type 2 diabetes. Konjac polysaccharide has a variety of biological functions, including improving the level of glucose and lipid metabolism, promoting immune function, preventing cell lipid peroxidation, and combating skin inflammatory factors.

How Does Konjac Glucomannan Work

Konjac glucomannan (KGM) is a kind of soluble dietary fiber in konjac. The content of KGM can reach 6% ~ 10% in mature fresh taro and 50% ~ 80% in Konjac powder. Konjac’s super satiety is mainly derived from Konjac glucomannan, which has super water absorption and can absorb water and expand to 100 times the original volume! KGM is almost not digested in the human gut, and it can continue to expand even after eating, bringing a stronger sense of fullness. It’s easy to fill up and low in calories. Glucomannan may treat constipation in the stomach and intestines by absorbing water to form a large fiber. It can also slow the absorption of sugar and cholesterol in the gut, helping to control blood sugar levels and lower cholesterol levels in people with diabetes.

Health Benefits of Konjac Glucomannan

There are an array of potential health benefits of Konjac Glucomannan, such as Weight Loss， Laxative Effect, Stabilizing Blood Sugar and so on, here we will browes some of its important Health Benefits as below:
Weight Loss
Preliminary evidence suggests that konjac glucomannan is well tolerated and may promote weight loss. For example, Keithley in the United States did a study on the mechanism of action of KGM on weight loss. Studies have found that whether in a normal diet or a high-calorie diet, KGM has a certain role in reducing weight. Therefore, the researchers speculate that the mechanism of KGM weight loss is that the intake of KGM food increases the viscosity of gastrointestinal contents, thereby prolonging the gastric empting time and increasing the sense of fullness of people, while reducing the absorption rate of small intestine food and reducing the fluctuations of glucose and insulin after meals. There is some evidence that KGM plays a beneficial role by promoting satiety and improving its safety and reducing the loss of energy in the stool.
Laxative Effect
First of all, KGM can promote bowel movement by absorbing a lot of water to increase the volume of stool. Secondly, KGM can improve intestinal flora. After KGM enters the intestine, it is collyzed by intestinal bacteria to produce short-chain fatty acids and stimulate intestinal peristalsis, all of which are conducive to defecation. Moreover, studies have shown that the consumption of KGM in constipated patients can increase the daily fecal wet weight and fecal water content, shorten the time of food operation in the intestine and the average defecation time, and increase the number of bifidobacterium. And eating KGM produces the effect of natural defecation, promoting defecation without causing diarrhea. It can improve the symptoms of chronic and habitual constipation.
Stabilizing Blood Sugar
An important measure for diabetes treatment is to control diet, because KGM does not contain calories, is not digested and absorbed after consumption, and has a sense of fullness, and can reduce and delay the absorption of glucose, so it is a good auxiliary food for diabetes. Studies have shown that KGM can significantly improve glucose metabolism, while insoluble fiber has no significant effect. Chengyu Huang et al. from West China University of Medical Science studied the influence of KGM on the blood sugar of diabetic patients, and the results showed that KGM has a hypoglycemic effect, and the hypoglycemic effect of heavy patients is better than that of light patients, and it is more effective in reducing postprandial blood sugar and fasting blood sugar. At the same time, KGM delays glucose absorption and also helps to inhibit hypoglycemia.
Reducing Blood Lipids and Anti-fatty Liver
The main components of blood lipids are triglycerides and cholesterol. KGM helps in lipid metabolism and can lower cholesterol and triglycerides. Professor Zhang Mao-yu studied 110 hyperlipidemia patients with KGM food. After eating konjac, serum TG (triglyceride), TC (cholesterol), LDL-C (low density lipoprotein cholesterol) were significantly reduced, and HDL-C (high density lipoprotein cholesterol) was significantly increased in 46 people. Fatty liver improved and blood lipid decreased. When the blood lipid reaches the normal level, it does not continue to decline, which plays a role in regulating lipid metabolism and preventing hyperlipidemia.
Anticancer
The results show that Konjac powder can obviously promote the immune function of mice and increase the thymus index and spleen index. It can promote the synthesis and release of interleukin-1 and tumor necrosis factor α by macrophages. In addition, it also has a certain promoting effect on improving the serum tumor necrosis factor α level. Therefore, KGM may be used as an immunomodulatory adjuvant food for the prevention and treatment of tumors. In addition, KGM was found to inhibit spontaneous liver cancer, liver injury induced by β-galactosamine, and colon cancer.

Konjac Glucomannan Side Effects

Avoid the use of KGM in people with abnormal esophageal or intestinal structure, which may cause difficulty swallowing, obstruction of the esophagus or stomach, and even the risk of suffocation. In addition, do not use pregnant and breastfeeding women, because the relevant safety is unknown. Because glucose-mannan has the potential to lower blood sugar, it should not be used in combination with hypoglycemic drugs or insulin, which may lead to hypoglycemia.
