Prebiotic Inulin Shown to Help Control Blood Sugar Levels
Soluble fiber has been shown to slow the absorption of sugar and reduce blood sugar spikes. A recent study found that taking supplements of the prebiotic soluble fiber inulin improved blood glycemic control.
Study participants included 49 women with type-2 diabetes. Over the course of two months, half of the women took 10 grams of inulin while the other half took a malodextrin placebo daily.
At the conclusion of the trial, the researchers noted an 8.5% improvement in fasting plasma glucose, a 10.4% improvement in glycosylated hemoglobin, and a 37% decrease in malondialdehyde, which is a marker of oxidative stress. They also noted an 18.8% increase in antioxidant capacity and a 4.4% increase in the activity of the antioxidant enzyme superoxide dismutase.
Researchers from the Tabriz University of Medical Sciences in Iran conducted the study. It was published in the April 2013 issue of Diabetes & Metabolism Journal.
Inulin is soluble dietary fiber that is non-digestible. It passes through to the large intestine and becomes healthy intestinal micro flora. Dandelion root, chicory root and elecampane root all have high concentrations of inulin.
Previous studies have shown that inulin strengthens the immune system, enhances the absorption of minerals such as calcium and magnesium, improves digestion and lowers cholesterol.
