Whey protein with fiber lowers blood sugar response to food

Whey protein with fiber lowers blood sugar response to food An estimated 30 million people in the U.S. have diabetes and at least twice that number have pre-diabetes, two conditions associated with dysregulation of blood sugar. Recent evidence indicates that regular consumption of whey protein may help manage blood sugar levels.  

Australian researchers wanted to find out if low doses of whey protein combined with fiber would be an effective strategy for significantly lowering blood sugar levels. The diabetic and pre-diabetic test subjects consumed a standardized breakfast consisting of 2 slices of bread, margarine, jam, and tea or coffee. Fifteen minutes before breakfast, subjects consumed water only (control condition) or a whey-fiber drink consisting of whey protein (17 grams), lactose (5 grams) and guar gum (5 grams). Compared to water only, the whey-fiber drink significantly reduced the blood sugar response to breakfast. For example, blood sugar levels 45 minutes after breakfast were 38 mg/dL lower when the whey-fiber drink was consumed 15 minutes before the breakfast. The whey-fiber drink reduced blood sugar levels during the 3 hours after breakfast by an average of 14 mg/dL.

Consuming a modest dose of whey with fiber prior to breakfast was effective at significantly decreasing blood sugar responses to a standard breakfast, and therefore may represent an effective strategy for better management of high blood glucose. Guar gum is a fiber from the seed of the guar plant. It is found in a few multi-fiber powders. You should expect similar results from more common fibers like psyllium, acacia, glucomannan, oat bran or chia seeds. Consider adding fiber to a whey shake to reduce the normal rise in blood sugar that occurs after a meal.
