What does olive oil contain? Composition and benefits

Olive oil, especially extra virgin olive oil (EVOO), is much more than a simple condiment. It's a cornerstone of the Mediterranean diet and a true "functional food," capable of positively impacting our health. But what exactly does olive oil contain to deserve this reputation?

Behind its color and flavor lies a complex chemical composition that is the true source of its renowned benefits. In this article, we'll take a detailed look at what olive oil contains, why it's so beneficial, and how to choose the best one for your table.

  • Origin and production : Olive oil comes from extracting the juice of olives, the fruit of the olive tree. Its production takes place primarily in Mediterranean countries, where the favorable climate and traditional techniques help preserve its properties.

  • Olive Oil Varieties : There are several varieties of olive oil, each with unique characteristics in terms of flavor and nutritional profile. From the delicate extra virgin variety to the versatile virgin variety, we can choose the one that best suits our culinary preferences. If you'd like to learn more about the various technical differences between olive oil, we invite you to read our article on the subject.

  • Health benefits : Olive oil is rich in heart-healthy monounsaturated fats and antioxidants like vitamin E, which help counteract the damaging effects of free radicals. Regular consumption of olive oil is associated with a reduced risk of heart disease and inflammation.

  • Culinary Uses : Thanks to its delicate flavor and varying degrees of fruitiness, olive oil is a versatile ingredient that lends itself to a wide range of culinary preparations. From salads and fish to baking, we can take advantage of its flavorful and healthy properties.

The Chemical Composition of Olive Oil: What's Really Inside?

When we analyze olive oil, its composition is divided into two main parts: a very large fraction that defines its "fat" nature and a very small fraction that contains its health secrets.

The Saponifiable Fraction (98-99%): Fatty Acids

This is the main part of the oil, composed almost entirely of triglycerides (fats). However, not all fats are created equal. Olive oil is famous for its lipid profile:

  • Oleic Acid (55-83%): This is the undisputed king. It is a monounsaturated fat (Omega-9) known for its ability to help maintain normal blood cholesterol levels, favoring HDL ("good") at the expense of LDL ("bad").

  • Polyunsaturated Fatty Acids (e.g. Linoleic Acid - 3.5-21%): Present in smaller quantities, they are essential fats that the body cannot produce on its own.

  • Saturated Fatty Acids (e.g. Palmitic Acid - 7.5-20%): Present in a much lower percentage than unsaturated fats.

The Unsaponifiable Fraction (1-2%): The "Super-Components"

This 1-2% is what turns a fat into a "superfood." It's in this small fraction that we find the bioactive compounds responsible for the oil's most powerful benefits. The main ones are:

  • Polyphenols: These are the most important. They act as powerful antioxidants and anti-inflammatories. Two notable names are Oleuropein (responsible for the bitter taste) and Oleocanthal (which causes the typical "tingling" in the throat, with an anti-inflammatory effect similar to that of ibuprofen). In particular, our specialty Mille is one of the oils with the highest concentration of polyphenols on the market.

  • Tocopherols (Vitamin E): Another powerful antioxidant that protects cells from oxidative stress and helps the oil last longer.

  • Sterols (e.g., Beta-sitosterol): Compounds that help reduce the absorption of cholesterol in the intestine.

  • Squalene: A compound that participates in the synthesis of good cholesterol and contributes to skin health.

The nutritional benefits of olive oil

Thanks to this unique composition, EVOO does not just season, but actively participates in our health.

  • Cardiovascular Protection: The combined action of oleic acid (which balances cholesterol) and polyphenols (which protect the integrity of blood vessels) is a panacea for the heart.

  • Anti-inflammatory Power: Oleocanthal, as seen, acts as a natural anti-inflammatory, helping to reduce chronic low-grade inflammatory conditions, which are at the root of many modern diseases.

  • Counteracts Cellular Aging: Polyphenols and Vitamin E fight free radicals, the main culprits of oxidative stress and the aging of our cells.

  • Brain Support: Some studies suggest that the antioxidant compounds in EVOO may help protect brain health and preserve cognitive function.

  • Gut Health: It appears to promote the balance of the intestinal microbiota, nourishing the "good" bacteria.

The health benefits of consuming olive oil

Consuming olive oil brings numerous health benefits. Here are some of the advantages of including this precious food in your diet:

  • Rich in healthy fats: Olive oil is a rich source of monounsaturated fats, such as oleic acid, which are beneficial for heart health. These healthy fats can help reduce the risk of cardiovascular disease.

  • Antioxidants: Olive oil contains powerful antioxidants, such as vitamin E and polyphenols, which help fight oxidative stress and inflammation in the body. These compounds help protect cells from damage and support the immune system.

  • Beneficial for brain health: The antioxidants found in olive oil may have positive effects on the brain, helping to protect against neuronal degeneration and improve cognitive function.

  • Anti-inflammatory effects: Extra virgin olive oil is known for its anti-inflammatory effects, which may help reduce the risk of chronic diseases related to inflammation, such as heart disease and diabetes. Source: PubMed (NIH - National Institutes of Health)

  • Promotes skin health: Thanks to its antioxidant and anti-inflammatory properties, olive oil can help keep skin healthy and radiant, protecting it from damage caused by free radicals.

  • Regulates blood sugar levels: As also indicated in the Fondazione Veronesi article " Extra Virgin Olive Oil, Elixir of Long Life ," the latter is also a panacea for our blood vessels. Olive oil can help improve insulin sensitivity and regulate blood sugar levels, offering benefits for those suffering from diabetes or wanting to prevent this condition.

Including olive oil in our daily diet can therefore bring numerous benefits to our health, both physically and mentally.

Olive oil as part of a balanced diet

We believe olive oil is an essential component of a balanced diet. Here's why:

Virgin olive oil vs. extra virgin olive oil: what's the difference?

We often hear about virgin and extra virgin olive oil, but what's the difference between the two? Here's what you need to know:

  • Production process: Virgin olive oil is obtained through mechanical processes, without the use of chemical solvents. Extra virgin olive oil, on the other hand, is produced with high-quality olives and without sensory defects, making it of superior quality.

  • Acidity: Virgin olive oil has a maximum acidity of 2%, while extra virgin has a maximum acidity of 0.8%. This indicates greater freshness and purity in the extra virgin oil.

  • Taste and aroma: Extra virgin olive oil has a richer and more intense flavor than virgin olive oil. Its aroma is fruitier and offers greater sensory complexity.

  • Culinary uses: Both oils can be used in cooking, but extra virgin olive oil is often preferred for raw dressings, such as in salads or finished dishes, while virgin olive oil can also be used for cooking at higher temperatures.

In short, the main difference between virgin and extra virgin olive oil lies in the quality of the olives used and the production process, which gives extra virgin oil a more intense flavor and aroma.

Tips for buying and storing olive oil

Here are some helpful tips to ensure optimal purchase and storage of olive oil:

  • Choose high-quality extra virgin olive oil: Opt for extra virgin olive oil produced locally or from regions renowned for their olive quality.
