Herbs and Spices: Variety Is Best
The newly published study by Hargrove and colleagues appears in the latest
issue of the Journal of Medicinal Food.
Hargrove tells WebMD that he purchased the 24 spices used for the study at a
"We showed that herbs and spices are powerful sources of antioxidants
and anti-inflammatory agents," Hargrove says. "About a teaspoon of
cinnamon, for example, is plenty to get these beneficial effects."
When blood sugar levels are high a process known as protein glycation
occurs, which produces compounds that promote inflammation. These are known as
AGE compounds (advanced glycation end-products). The researchers found a strong
correlation in polyphenol content in herbs and spices tested and their ability
to block the formation of AGE compounds.
Spices -- derived from seeds, berries, bark, or roots -- tended to have
higher levels of polyphenols than dried herbs, derived from plant leaves.
Of the herbs tested by the researchers, oregano, marjoram, and sage had the
highest polyphenol levels, followed by thyme, Italian seasoning, tarragon,
mint, and rosemary. Black pepper had the lowest polyphenol content of any of
the tested herbs and spices.
But researcher Diane Hartle, PhD, says it is best not to focus on any single
herb or spice, suggesting that seasoning foods with a variety of spices is
In a news release, Hartle noted that different polyphenols have different
mechanisms of action within the body. "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 calorie content."
