Konjac is a kind of plant that can live upto 3 years long, it mostly grows in the Southwest China mountainious region, the same beautiful area where Pandas live, Konjac plant has a very nice flower and fruit. The konjac root (tube) is rich of glucomannan fiber, 40-60%
dried konjac root is glucomannan fiber.
Konjac Root Fiber
Konjac fiber has the highest viscosity soluble fiber in nature, according to medical research, the higher the viscosity, the better to control blood sugar levels. Konjac fiber is the best soluble fiber for people with diabetes that want to control blood sugar level naturally.
How is Konjac Glucomannan unique from
other soluble fiber?
Konjac Glucomannan is the most viscosity soluble fiber
in nature - it forms an extremely viscous solution.
Konjac Glucomannan has the highest molecular weight of any dietary
fiber known to science - molecular weight is between 200,000-2,000,000
Konjac Glucomannan has the highest water holding capacity of any soluble
fiber - up to 100 times its own water weight.
Konjac Glucomannan can form either a reversible or a thermo-non-reversible

What are the health benefits of soluble
The US Food and Drug Administration has approved food manufacturer
use of the following information on product labels:
- Diets low in saturated fat and cholesterol that include fruits,
vegetables, and grain products, which also contain fiber (particularly soluble fiber), may reduce the risk of coronary heart disease.
- Diets low in saturated fat and cholesterol that include 3g of soluble fiber from whole oats per day may reduce the risk
of heart disease.
- A low-fat diet rich in fruits, vegetables, and whole grains containing
fiber, particularly soluble fiber, may lower blood cholesterol
levels, reduce the risk of heart diseases, and possibly prevent
some types of cancer.
- Diets low in saturated fat and cholesterol that include a daily
intake of soluble fiber from whole oats or psyllium seed
may reduce the risk of heart disease.
The American Dietetic Association recommends that people consume
20 to 35 grams of fiber per day, of which 5 to 10 grams should be
soluble fiber. However, Americans typically average only about 12
to 17 grams of total fiber and only 3 to 4 grams of soluble fiber
a day - about half the recommended amount.
How does soluble fiber work?
Soluble fiber is the only known food component that will lower blood
cholesterol when you add more to your diet. Foods high in soluble
fiber help prevent sugar from rising too high after meals by keeping
food in the stomach longer. Sugar is absorbed more slowly, preventing
free fatty acids and triglycerides from rising too high after meals.
Free fatty acids bind to insulin receptors and prevent insulin from
doing its job of driving sugar from the bloodstream into cells. In
addition, soluble fiber does the following:
- It binds to fat in the intestines, preventing some fat absorption.
- It dissolves fluids in the large intestine and forms a gel that
binds with bile acids in the intestines. As a result, the liver
converts more cholesterol to bile acids, and blood cholesterol levels
- It slows digestion and the absorption of nutrients, resulting
in a slow and steady release of glucose from accompanying carbohydrates.
- It soaks up excess bile acids found in the intestinal tract -
the same acids that are converted into blood cholesterol.
- It delays stomach emptying, triggering satiety (a feeling of
fullness) that can be helpful in people with type 2 diabetes trying
to achieve weight loss goals.
Soluble Fiber Intake & Type 2 Diabetes
Mellitus: The Research
Research proves that the higher the viscosity of soluble fiber, the
better the control of blood sugar level in patients with Type 2 diabetes:
New England Journal of Medicine (May 11, 2000. v342: 1392-1398)
Beneficial effects of high dietary fiber intake in patients with
type 2 diabetes mellitus.
"A high intake of dietary fiber, particularly of the soluble
type, above the level recommended by the ADA, improves glycemic control,
decreases hyperinsulinemia, and lowers plasma lipid concentrations
in patients with type 2 diabetes"
Excell Nurse Pract.(September 2000; 4 (5): 272-6)
Dietary fiber and type 2 diabetes.
"Water-soluble fiber appears to have a greater potential
to reduce postprandial blood glucose, insulin, and serum lipid levels
than insoluble fiber. Viscosity of the dietary fiber is important;
the greater the viscosity, the greater the effect. "
Hypotheses. (June 2002; (6): 487-90)
Glucomannan minimizes the postprandial insulin surge: a potential
adjuvant for hepatothermic therapy.
"Glucomannan (GM) is differentiated from other soluble fibers
by the extraordinarily high viscosity of GM solutions. Administration
of 4-5g of GM with meals, blended into fluid or mixed with food, can
slow carbohydrate absorption and dampen the postprandial insulin response
by up to 50%. "

Konjac-mannan (glucomannan) improves glycemia and other associated
risk factors for coronary heart disease in type 2 diabetes. A randomized
controlled metabolic trial.
"KJM fiber added to conventional treatment may ameliorate glycemic
control, blood lipid profile, and SBP in high-risk diabetic individuals,
possibly improving the effectiveness of conventional treatment in
type 2 diabetes"

Beneficial effects of viscous dietary fiber from Konjac-mannan
in subjects with the insulin resistance syndrome: results of a controlled
"A diet rich in high-viscosity KJM improves glycemic control
and lipid profile, suggesting a therapeutic potential in the treatment
of the insulin resistance syndrome."
of the American College of Nutrition (2003, February, 22(1): 36-42)
Konjac supplement alleviated hypercholesterolemia and hyperglycemia
in type 2 diabetic subjects--a randomized double-blind trial.
"The KGM supplement improved blood lipid levels by enhancing
fecal excretion of neutral sterol and bile acid and alleviated the
elevated glucose levels in diabetic subjects. KGM could be an adjunct
for the treatment of hyperlipidemic diabetic subjects."
Are there natural food sources of soluble
Soluble fiber is found in oats, oatmeal, oat bran, beans, legumes,
barley, citrus fruits, and psyllium. It can also be found in gums,
including; Konjac gum, vegetable gum, pectin, guar gum and gum Arabic.
But generally, most have only a small percentage soluble fiber. Oat
bran contains the highest level of soluble fiber, about 14%. All other
grains contain much less. In comparison, fresh Konjac contains an
average of 13% dry matter, of which 64% is glucomannan, making glucomannan
the richest soluble fiber resource in nature.
How can Konjac Glucomannan powder be
Drink it with water:
Three times daily before each meal, briskly stir one level
teaspoon konjac powder (about 4 gram) in 1 cup water, drink immediatly
before the begins to gel.
Use it as thickener:
Like cornstarch, but with 10 times the viscosity, Konjac Glucomannan
powder thickens sauces, gravies, puddings and pie fillings without
Konjac Glucomannan is easy to use, dissolving easily into hot or cold
Can Konjac pasta be made at home?
In addition to buying Konjac foods in the super market or online,
you can them make them yourself. You can easily prepare Konjac foods
at home using the following simple recipe:
- 2 teaspoon of glucomannan (contains 6 grams of soluble fiber.)
- 1/8 teaspoon of pickling
lime, a food grade calcium hydroxide.
Pour 2 cups of cold water into a pot. Stir in a 1/8 teaspoon of pickling
lime. Then, add 2 teaspoon of Konjac Glucomannan powder, stirring
continuously to a boil. Boil the mixture for about 3 minutes. Remove
from heat. A thermally stable (non-reversible) gel is formed once
the mixture cools down. Cut gel into small pieces, dip in water or
steam about 3-5 minutes and then cook in the way you like.
How is Konjac pasta prepared?
Konjac pasta can be boiled or cooked with vegetables, meat, or seafood.
It can then be tossed with sauces, vinegar, hot salsa, or ingredients
like pepper, onion, or garlic. To prepare Konjac pasta, simply dip
it in water for 3-5 minutes, and then prepare it any way you like.
