Raisins May Help Reduce Blood GlucoseJune 29, 2012
Raisins are a great source of potassium. Now there may be another reason to eat them.
Research was presented that suggests eating raisins three times a day may significantly lower post-meal glucose levels when compared to common alternative snacks of equal caloric value. The subjects were those who had slightly elevated blood pressure (prehypertension).
The study was conducted at the Louisville Metabolic and Atherosclerosis Center (L-MARC) by Harold Bays, MD, medical director and president of L-MARC. Please watch the enclosed video of Dr. Bays’ discussing key findings from the study.
“Raisins have intrinsic properties that could support heart and vascular health; however, we believe this is the first controlled study to specifically and scientifically support raisins’ blood pressure-lowering effects compared to other snacks,” said Dr. Bays.
Subjects were randomly assigned to snack on raisins or pre-packaged commercial snacks that did not contain raisins or other fruits or vegetables, three times a day for 12 weeks. This study showed that, compared to the control snacks, raisins significantly decreased post-meal glucose levels – by about 16%.
The study was funded by the California Raisin Marketing Board through a grant to the L-MARC Research Center in Louisville, Kentucky.
“Raisins have a relatively low glycemic index and contain fiber and antioxidants, all factors which contribute to blood sugar control,” said James Painter, Ph.D., R.D., and nutrition research advisor for the California Raisin Marketing Board. “Decreasing blood sugar and maintaining normal hemoglobin A1c levels is important because it can prevent long-term damage to the heart and circulatory system.”
This is a very small study, of course, but worth watching for further developments.
