Cranberries May Help in Lowering Diabetes Risk

Studies reveal polyphenols in cranberries can help manage blood sugar levels and protect against inflammation as part of a healthy balanced lifestyle

LAKEVILLE-MIDDLEBORO, Mass.--(BUSINESS WIRE)--Cranberries continue to impress scientists with their whole body health benefits as evidenced by the profusion of cranberry studies presented at the 2015 Experimental Biology conference in Boston last week. The research buoyed the tart fruit’s reputation for supercharging well-being and spotlighted the cranberry’s emerging role in helping to maintain blood sugar levels, a finding that could provide promising news for the future management of diabetes risk factors.

Cranberries and Managing Diabetes
Given cranberries are naturally low in sugar, fat-free and a good source of fiber, researchers from the University of Oklahoma and Oklahoma State University joined forces to determine whether cranberry consumption could improve blood sugar levels in adults with Type 2 diabetes¹.

The spotlight study split participants into two groups: Both ate a high-fat breakfast, however, one group had dried cranberries with their breakfast, while the other was given bananas. Blood draws taken after the meal revealed modest but notable beneficial effects in blood sugar among those who had eaten cranberries with their breakfast.

“These findings are very promising,” explained Dr. Arpita Basu of Oklahoma State University. “It suggests there may be a buffering effect for blood sugar from eating polyphenol-rich cranberries. Which means that simply adding a serving of cranberries to a meal could help protect against the spikes and dips in blood sugar that are related to internal damage of blood vessels.”

The findings set the stage for future research, which may provide welcome news for the 29.1 million people in the U.S. living with diabetes each year².

The Body’s Inner Armor
Among the common themes emerging from the other featured studies is that cranberries provide a rich source of protective compounds called polyphenols that support our body’s antioxidant enzymes so that they are better able to protect our body against inflammation, in effect, strengthening the body’s own defense system³.

“The collective research shows that when you consume cranberries – whether in whole fruit or liquid form– their protective compounds are absorbed and present in the body,” said Dr. Christina Khoo, Director of Research Sciences, Ocean Spray Cranberries, Inc. “This is an important finding as we continue to understand the protective role of cranberries and the many applications for whole body health.”

Cranberries contain more naturally occurring polyphenols than most other common fruits and studies suggest that consuming cranberries may have a positive effect on health by maintaining cellular health. Here’s what the latest research revealed about the protective benefits of this exceptional fruit:

• 25 percent less cell damage was experienced by human liver cells bathed in cranberry polyphenols for 20 hours, as compared to untested cells⁴. Unprotected over time, this cell damage could lead to heart disease and a number of chronic diseases⁵.
• 15.2 oz., or two glasses, of high polyphenol cranberry extract beverage consumed daily over time was enough to promote the activity of the body’s natural antioxidant enzymes, which fight off damaging free radicals in our bodies⁶. The benefit of less free radicals is clear in lower inflammation levels.
• 8 weeks of drinking low-calorie cranberry juice may help maintain plasma cysteine, an essential amino acid for synthesis of glutathione, an important component of our body’s own defenses⁷, and may help keep our bodies balanced and functioning optimally⁷.

These studies continue to build on the body of evidence supporting cranberry products as part of a healthy diet and balanced lifestyle. For more information about the whole body health benefits of cranberries, visit http://bit.ly/1F9ynGf.
