What is High Phenolic EVOO and How is it Good for you?

Over two thousand years ago, Hippocrates and Dioscorides referred to early harvest olive oil as medicinal. Modern science has identified the polyphenols, or more accurately phenolic compounds, that are health protective and continue to research the effectiveness  of these phenols for the prevention and treatment of many of todays chronic illnesses, including heart attack and stroke, high blood pressure, rheumatoid arthritis, obesity, Alzheimer’s, Parkinson’s, Type II Diabetes and cancer.

It is well known that most illness is the result of inflammation and it is the phenolic compound Oleocanthal that is known for its anti-inflammatory properties. Oleocein is a known antioxidant. These compounds are only found in olive oil. EVOOs that test high in these and other phenols are in fact nutraceutical and, since olive oil is a natural food, daily consumption of High Phenolic EVOO is a smart choice for optimum health, vitality and longevity.

What Makes Aristoleo an Authority on High Phenolic EVOO?

In 2012, the EU made a health claim labelling regulation 432-2012. In it is stated that olive oils with polyphenols over 250 mg/kg can put a health claim on the label as it reduces LDL oxidation. In the same year, Dr. Prokopios Magiatis and Dr. Eleni Melliou of the University of Athens discovered a method to accurately measure individual phenolic compounds in olive oil using NMR (Nuclear Magnetic Resonance). The following year they invented a test kit to measure the combined phenolic compounds Oleocanthal and Oleacein. It is the AristoleoTest Kit.

Aristoleo Ltd. patented the invention and has dedicated the interim years to identifying High Phenolic EVOOs, expanding consumer awareness of the health benefits of High Phenolic EVOO and continuing to work with Drs. Magiatis and Melliou and are now partner in the EU funded 3-year, 5-country ARISTOIL Interreg MED Program to study High Phenolic EVOO production and how to deliver it to the world. We are proud and love what we do!
