Highly polyphenolic olive oil: naturally healthy
High polyphenol olive oil is valued for its high content of polyphenols - antioxidant plant compounds that offer numerous health benefits. Studies show that olive oils with a polyphenol content of over 250 mg/kg are particularly valuable for health.
Health Benefits of High Polyphenol Olive Oil
Highly polyphenolic olive oil is not only a culinary delight, but also offers a variety of health benefits. Polyphenols, the natural secondary plant substances, not only give olive oil its distinctive taste, but also contribute significantly to its positive effects on health. Here are some of the most important benefits in detail:
1. Cardiovascular protection
Polyphenols in olive oil promote heart health by helping to regulate blood pressure and maintain the elasticity of blood vessels. Studies show that regular consumption of polyphenol-rich foods, such as extra virgin olive oil, can significantly reduce the risk of heart disease. The antioxidant effect of polyphenols protects LDL cholesterol particles from oxidation, a key factor in the development of atherosclerosis. [Studie]
2. Antioxidant effect
The antioxidant power of polyphenols protects cells from the damaging effects of free radicals that can be caused by environmental factors such as air pollution, UV radiation or stress. As a result, polyphenol-rich olive oil prevents cell damage that is associated with aging processes and chronic diseases such as cancer and diabetes. Studies suggest that olive oil high in polyphenols plays an important role in an antioxidant and anti-inflammatory diet. [Studie]
3. Anti-inflammatory properties
Chronic inflammation is an underlying factor in many serious diseases, including arthritis, Alzheimer's disease, and heart disease. Polyphenols in olive oil have anti-inflammatory effects by reducing the activity of pro-inflammatory enzymes. This may help lower the risk of chronic inflammation and related diseases. [Studie]
4. Support of the immune system
High-polyphenol olive oil contains compounds that can strengthen the immune system by supporting the body's defenses against infections and diseases. The polyphenols promote the healthy function of immune cells, thus contributing to a balanced and efficient immune system. [Studie]
5. Promoting cognitive health
Studies show that polyphenols in olive oil may have neuroprotective properties by reducing oxidative damage in the brain and supporting nerve cell function. Regular intake of polyphenol-rich olive oil may help reduce the risk of age-related cognitive decline and neurodegenerative diseases such as Alzheimer's. [Studie]

Polyphenol content: Why is it not always stated?
Good olive oil usually has high polyphenol levels. However, we only list these if an analysis is available. Unfortunately, this is not the case for all olive oils, as there is no legal minimum value and measurement is not mandatory. For cost reasons, the value is often omitted in standard analyses.
How do polyphenols get into olive oil?
Polyphenols enter olive oil by being extracted from the flesh and skin of the olive during the pressing process. The polyphenol content depends heavily on the type of olive, the degree of ripeness, the growing conditions and the processing. Olive oil with high polyphenol content is mainly produced by early harvesting and careful cold extraction.
Important factors that influence polyphenol content:
- Olive variety: Some olive varieties, such as Koroneiki or Picual, are naturally richer in polyphenols than others. These varieties are often specifically selected for the production of high-polyphenol olive oil.
- Ripeness: Unripe olives that are still green contain the highest concentration of polyphenols. During ripening, polyphenol levels decrease as they are converted into sugars, making the oil milder in taste.
- Processing techniques: Cold extraction below 27 °C is crucial to preserve the heat-sensitive polyphenols. Gentle mechanical processes also prevent oxidation and preserve the natural antioxidants in the oil.
- Growing conditions: Environmental factors such as drought stress promote the production of polyphenols in the olive tree, as these serve as protective substances against environmental influences. Soil quality and sufficient sunlight also play an important role in the development of polyphenols in the olives.
Which olive oil has the highest polyphenol content?
In Spain, Cornicabra and Picual olive oils in particular are among the varieties with the highest polyphenol content. These varieties often have particularly high concentrations and are therefore ideal for those looking for an olive oil with a high polyphenol content .
