An exceptional olive oil, naturally rich in polyphenols
What does “phenolic olive oil” mean?
Polyphenols are natural compounds found in plants, known for their powerful antioxidant effects. Olive oil contains around twenty five types of polyphenols, among which the most important are hydroxytyrosol, oleuropein and oleocanthal. These compounds are recognised for their antioxidant and anti inflammatory properties, as well as for their role in supporting good cardiovascular health.
The phenolic composition of Les Jardins d’Olya olive oil
Our olive oil shows an exceptional phenolic composition, as demonstrated by the results* of our latest cuvée:
- Total phenols: 449.2 mg/kg (compared with 100 to 200 mg/kg for a standard olive oil)
- Hydroxytyrosol: 64.1 mg/kg (compared with 5 to 10 mg/kg for a standard olive oil)
The level of hydroxytyrosol is a particularly reliable indicator, and ours is far above that of a standard olive oil.
According to a study published in Medicines**, hydroxytyrosol is considered one of the most effective antioxidants among all the phenolic compounds found in olive oil. Its regular consumption is associated with several benefits, including antioxidant and anti inflammatory effects, protection of cells against oxidative stress and support for cardiovascular health***.
According to European regulations (EU health claim), the polyphenols in olive oil contribute to the protection of blood lipids from oxidative damage. This claim applies when consuming at least 20 g of virgin or extra virgin olive oil per day containing a minimum of 5 mg of hydroxytyrosol and its derivatives, such as oleuropein and tyrosol. Based on these health claims, an olive oil is considered phenolic from 250 mg/kg upwards.
A few definitions to better understand their impact on the body
Antioxidants and free radicals
Free radicals are unstable molecules that naturally form within the body. They are produced through biological processes such as cellular respiration, but also through external factors including pollution, tobacco, stress and an unbalanced diet. These reactive molecules can damage our cells, accelerate ageing and play a role in the development of chronic diseases such as cardiovascular disorders and certain cancers.
To counter these attacks, the body has a natural defence system: antioxidants. These substances neutralise free radicals before they can cause harm. They are essential for maintaining biological balance and preserving overall well‑being.
By favouring a diet rich in antioxidants, we help our body fight oxidative stress and its negative effects. A healthy lifestyle, including a balanced diet, regular physical activity and effective stress management, strengthens this natural protective shield.
Oxidative stress
Oxidative stress is a biological phenomenon that occurs when the body faces an overload of free radicals that exceeds the capacity of antioxidants to neutralise them. This imbalance can damage cells, accelerate ageing and contribute to the development of certain chronic diseases.
The key to reducing its effects lies in a healthy lifestyle and a diet rich in antioxidants. These molecules neutralise free radicals and protect our cells. Incorporating antioxidants into daily life helps preserve cellular vitality and strengthen overall well‑being.
