Barley Fiber Improves Blood Sugar Control
Fiber is known to be one of the most important dietary factors for healthy blood sugar regulation and diabetes prevention. A study in Nutrition and Metabolism supports this, finding that a drink made with a soluble fiber derived from barley, called barley beta-glucan, improved the body’s responsiveness to insulin and improved blood sugar control in people with mildly elevated blood glucose levels.
Fifty overweight or obese adults who had high blood glucose levels but did not meet the criteria for type 2 diabetes participated in the new study. They were coached in therapeutic lifestyle changes with a goal of weight maintenance, and were assigned to receive flavored drinks providing 6 grams per day of barley beta-glucan, 3 grams per day of barley beta glucan, or placebo for 12 weeks.
