Olive oil is one of the most well-known components of Mediterranean cuisine. Used in a wide range of recipes for centuries, this natural oil continues to hold an important place in modern dietary patterns thanks to its distinctive flavour and versatility.

Olive oil is a plant-based oil obtained from olives and is composed primarily of monounsaturated fatty acids. It also naturally contains various plant compounds and polyphenols.¹

So why does olive oil attract so much attention, and how can it be incorporated into everyday eating habits?

What Is Olive Oil?

Olive oil is a natural oil produced by pressing olives. Different varieties are available depending on the production and processing methods used. Extra virgin olive oil, in particular, is considered one of the least processed forms and may retain more of its naturally occurring compounds.²

As one of the primary fat sources in the Mediterranean dietary pattern, olive oil can be used in salads, cooked dishes, breakfasts, dressings and many other recipes.¹

What Does Olive Oil Contain?

The majority of olive oil consists of monounsaturated fatty acids. Oleic acid is one of the most abundant naturally occurring fatty acids found in olive oil. In addition, olive oil may contain polyphenols, tocopherols and various plant-derived compounds.³

Factors such as harvesting time, production methods and storage conditions can influence the composition of olive oil. Therefore, both production quality and storage practices are important considerations.³

Why Is Olive Oil Popular?

Research has shown that olive oil can be included as part of a balanced and varied diet. However, like any food, it should not be viewed in isolation. Overall dietary patterns remain the most important factor.¹

Within a balanced eating plan, olive oil may:

• Contribute to dietary fat variety.

• Add flavour and texture to a wide range of dishes.

• Serve as a plant-based oil option.

• Be included as a commonly used fat source within Mediterranean-style eating patterns.¹ ²

How Can Olive Oil Be Used in Everyday Meals?

Olive oil is highly versatile and can be incorporated into daily meals in many ways.

For example, it can be:

• Drizzled over salads.

• Used in vegetable dishes.

• Added to breakfast recipes.

• Included in homemade dressings and sauces.

• Used in roasting, baking or marinades.

When used in moderation, olive oil can form part of balanced meals that include a variety of food groups.¹

What Is the Difference Between Extra Virgin Olive Oil and Other Olive Oils?

Extra virgin olive oil is produced using mechanical extraction methods and is not subjected to refining processes. As a result, it may retain more of its naturally occurring aromatic compounds and plant constituents.²

When selecting olive oil, consumers often consider factors such as production method, flavour profile and intended culinary use.

What Should You Look for When Choosing Olive Oil?

When purchasing olive oil, it is useful to consider the product's origin, production standards and storage conditions.

Points to consider include:

• Choosing products from reliable producers.

• Reviewing product labels carefully.

• Selecting oils stored in appropriate packaging.

• Protecting the oil from excessive heat and light exposure.

To help maintain quality, olive oil is generally stored in a cool, dark place away from direct sunlight.³

Why Does Olive Oil Quality Matter?

The quality of olive oil depends not only on the olives used but also on harvesting, production and storage practices.

When evaluating olive oil, some commonly considered quality indicators include:

• Polyphenol content.

• Acidity level.

• Harvest date.

• Production method.

• Storage conditions.

Extra virgin olive oils with higher polyphenol levels and lower acidity values are often preferred by consumers seeking premium-quality products.² ³

Olive Oil and Balanced Nutrition

Nutrition experts emphasise the importance of overall dietary patterns rather than focusing on individual foods. Olive oil can be included as part of a varied eating plan alongside vegetables, fruits, whole grains, legumes and different protein sources.¹

Developing sustainable eating habits, incorporating a variety of foods and choosing minimally processed ingredients are commonly recognised approaches to balanced nutrition.

With its distinctive flavour, versatility and natural composition, olive oil continues to be one of the most widely used plant-based oils in kitchens around the world.
