Reserveratrol May Improve Blood Sugar Spikes
Studies have shown that resveratrol offers many health benefits, including lowering cholesterol, improved liver function and better brain health. A study published in The Journals of Gerontology: Series A on January 4, 2012 suggests that this powerful antioxidant may also help reduce blood sugar spikes after eating and improve insulin sensitivity.
The Albert Einstein School of Medicine based researchers recruited 10 adults with an average age of 72. All of the participants had age-related glucose intolerance. A decline in glucose tolerance is most prominent after the age of 60, as people tend to gain more weight and become less fit and more sedentary as they age.
The participants were split into three groups and assigned to take different amounts of resveratrol daily for four weeks:
• One group consumed 1 gram daily
• The second group consumed 1.5 grams daily
• The third group consumed 2 grams daily
At the conclusion of the study, the researchers noted that sugar spikes were much lower after eating for all three groups when compared to the baseline data. Insulin sensitivity was also noticeably improved across the board. Improved insulin sensitivity means the body is better able to process glucose.
The researchers were careful to note that this was a pilot study and that larger, double-blind studies need to be conducted to conclusively determine the effect of resveratrol on metabolism and vascular function.
Resveratrol can be found in red wine, grapes, grape seed extract, and peanuts. A glass of red wine a day can provide a good amount of resveratrol, but excess drinking will reverse the positive health benefits. Another good way to get resveratrol is through a high quality supplement.
