A recent study, co-sponsored by Gaea and The Captain Vassilis Foundation, in cooperation with the University of California, Davis and the US Department of Agriculture, revealed the results of the first-ever human trial testing the effects of different qualities of extra virgin olive oils on health benefits.
The most significant finding that sets this study apart is the direct parallel drawn between the quality of an EVOO and the correlated health benefits— quality equates to higher benefits.
Additional findings and results from the study's findings, include:
Certain EVOOs may have medicinal benefits: EVOOs contain a wide array of compounds whose relative abundances differ among olive cultivars. Many of these compounds have demonstrated anti-oxidant and anti-inflammatory properties. While the total phenolic content of an oil is a reasonable measure of its anti-oxidant capacity, "medicinal" effects may be derived from specific compounds.
Not all EVOOs are created equal: This study demonstrates that oils rich in natural NSAIDs can produce NSAID-dependent effects in humans when eaten, but that there are a wide range of such responses among individuals, needing further investigation. Therefore, all EVOOs are not created equal and the total phenolic content of oils do not show how they are different, while in parallel a relation between high quality and health protection is clearly observed.
Greek Variety of EVOO showed to be the most effective in having cardioprotective activities: High quality Greek olive oil from the Koroneiki variety, being rich in oleocanthal, a natural non-steroid antioxidant and anti-inflammatory substance, offers significantly more effective protection from cardiovascular diseases, equal to the effect of aspirin and ibuprofen.
