Researchers at the University of Georgia have opined that herbs and spices can ward off the dangerous health fallouts of high blood sugar. The study, which appears in the current issue of the Journal of Medicinal Food, tested extracts from 24 common herbs and spices. Their results reveal that the antioxidants in these herbs naturally stall the tissue damage and inflammation caused by high levels of blood sugar.
In addition to finding high levels of antioxidant-rich compounds known as phenols, they revealed a direct correlation between phenol content and the ability of the extracts to block the formation of compounds that contribute to damage caused by diabetes and aging.

Hargrove explained that when blood sugar levels are high, a process known as protein glycation occurs in which the sugar bonds with proteins to eventually form what are known as advanced glycation end products, also known as AGE compounds.
The acronym is fitting because these compounds activate the immune system, resulting in the inflammation and tissue damage associated with aging and diabetes.
The researchers found a strong and direct correlation between the phenol content of common herbs and spices and their ability to inhibit the formation of AGE compounds.
Spices such as cloves and cinnamon had phenol levels that were 30 percent and 18 percent of dry weight, respectively, while herbs such as oregano and sage were eight and six percent phenols by dry weight, respectively.
For comparison, blueberries - which are widely touted for their antioxidant capabilities - contain roughly five percent phenol by dry weight.
Study co-author Diane Hartle, associate professor in the UGA College of Pharmacy, said various phenols are absorbed differently by the body and have different mechanisms of action, so it's likely that a variety of spices will provide maximum benefit.
"If you set up a good herb and spice cabinet and season your food liberally, you could double or even triple the medicinal value of your meal without increasing the caloric content," she said.
She added that controlling blood sugar and the formation of AGE compounds can also decrease the risk of cardiovascular damage associated with diabetes and aging.
