Phenols found in olive oil benefit blood vessels

According to a new study published in the November 2005 issue of the Journal of the American College of Cardiology, phenolic compounds found in olive oil may help explain the cardiovascular health benefits associated with the Mediterranean Diet.

Phenolics are plant-based compounds believed to have antioxidant, anti- inflammatory, and anticlotting properties that are found in higher concentrations in virgin olive oil.

In this study researchers found an improvement in the functioning of the endothelium (the inner lining) of small blood vessels, and in the concentrations of certain components of blood serum, after study subjects consumed a polyphenol-rich meal. But no such changes were found after the same study subjects consumed a low-phenolic meal.

Although more studies are needed to confirm these results, these findings may help to explain some of the heart health benefits associated with the Mediterranean diet.
