The Efficacy and Role of Konjac Glucomannan
Although in the eyes of most people, the impression of konjac is only delicious! But the advantages of konjac don’t stop there!
Unlike ordinary tuber and root crops, konjac tuber contains very little starch, and its main component is konjac glucomannan Powder. Don’t underestimate it, the main performance of konjac is basically related to it.
- Helps lose weight; the most famous role of konjac is to lose weight! How exactly does it do? Glucomannan in konjac is a water-soluble dietary fiber, which can absorb water to form a gel, and its volume expansion can reach about 50 times. After eating, you will feel full and avoid eating too many calories. In addition, when glucomannan enters the stomach, it can form a viscous konjac gum solution, prolong the passage of food from the stomach to the small intestine, and cover the surface of the intestinal mucosa to form a diffusion barrier to delay digestion and absorption of nutrients. In one study of obese people, subjects who took glucomannan daily for 8 weeks lost an average of 5.5 pounds without reducing their diet or changing their exercise habits.
- Lower blood sugar and reduce insulin resistance As mentioned above, soluble fiber absorbs more water and prolongs the digestion time, so it can slow down the rapid rise of postprandial glucose, thereby reducing blood sugar and insulin levels. In a 2007 study, people with type 2 diabetes took a single dose of glucomannan before consuming glucose. Compared with the blood sugar after taking the placebo, the blood sugar dropped significantly after 2 hours.
- Lowering cholesterol and blood lipids Glucomannan can combine with cholesterol in the digestive tract, hinder the absorption of triglycerides and cholesterol, and effectively inhibit the active transport of bile acids in the ileal mucosa, affecting the circulation of bile acids. A review of 14 studies found that taking glucomannan significantly reduced levels of “bad” LDL cholesterol and triglycerides.
- Maintain intestinal health. After glucomannan enters the digestive tract, it can increase gastrointestinal motility and fecal excretion, promote the decomposition of unsaturated fatty acids, increase the acidity in the intestinal tract, and is conducive to a large number of beneficial microorganisms such as lactic acid bacteria and bifidobacteria Reproduction, and effectively inhibit pathogenic bacteria and toxins, play the role of laxative.
