Research proves that the higher the viscosity of soluble fiber, the better the control of blood sugar level in patients with Type 2 diabetes:
The 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"
Clin 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. "
Med 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%."
Diabetes Care (1999 Jun v22, i6; 913-919)
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"
Diabetes Care (2000; 23: 9 - 14)
Beneficial effects of viscous dietary fiber from Konjac-mannan in subjects with the insulin resistance syndrome: results of a controlled metabolic trial.
"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."
Journal 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."
