Refined Olive Oil: What Is It and Is It Bad for Your Health?

Given the recent challenges faced by the olive oil industry due to the high price of olive oil on the market, many consumers are now exploring other varieties of olive oils — including some lesser-known types.

One of the most frequently asked questions is what is refined olive oil and what does it actually mean.

In simple terms, refined olive oil is a type of olive oil that has undergone a refinement process to remove impurities and improve its taste, color, and stability.

This oil is produced from olive oils that are not suitable for direct human consumption due to the high amount of impurities they contain.

Because of this, many people wonder about the impact of refined olive oil on health and whether it is safe to consume regularly.

To clear up the myths surrounding this oil, it’s essential to understand how it’s made and how it can affect our bodies.

Is Refined Olive Oil Bad for Your Health?

There’s some debate about whether refined olive oil is harmful to your health.

Unlike extra virgin olive oil (EVOO), which is extracted through mechanical methods and retains all its natural properties, refined olive oil goes through chemical and heat treatments to make it suitable for consumption.

Some studies suggest that these processes may remove part of the beneficial compounds found in EVOO — such as antioxidants and healthy fatty acids — altering the oil’s nutritional profile.

However, refined olive oil still contains a significant amount of oleic acid, a type of monounsaturated fat that has been linked to cardiovascular health benefits.

So, to answer the question “Is refined olive oil good for your health?” — yes, it can be. However, extra virgin olive oil will always remain the healthiest and highest-quality option.

Differences Between Refined and Unrefined Olive Oil

Unrefined olive oil, or extra virgin olive oil, is extracted from olives through mechanical means — without chemicals or high temperatures.

This type of oil retains all its natural properties, including aroma, flavor, and nutrients.

On the other hand, refined olive oil is subjected to a refinement process involving chemical agents and heat to remove impurities.

While this can slightly affect its nutritional quality, refined olive oil still has many practical uses. For example, it’s ideal for high-temperature cooking, such as frying or baking, because it has a higher smoke point than EVOO.

Refined olive oil is also commonly used in restaurants, food manufacturing, and canning industries thanks to its affordable price and versatility.

Even so, it remains a higher-quality option compared to oils like soybean, palm, or rapeseed oil — which are often used in processed foods and contain high levels of saturated fats.

These industrial oils are not recommended for regular consumption due to their negative health effects.

How Is Olive Oil Refined? The Full Process Explained

The refining process of olive oil involves several stages, usually combining chemical treatments and high temperatures. Here are the main steps:

1. The oil first undergoes degumming or purification to remove insoluble impurities.

2. It is then neutralized with chemical agents (such as caustic soda) to eliminate free fatty acids, and decolorized through filtration or treatment with absorbent clays.

3. Finally, it is deodorized to remove unwanted odors and volatile compounds responsible for off-flavors.

During deodorization, the oil can be exposed to temperatures of up to 250°C, causing a loss of many of its natural antioxidants.

If you’re wondering how to refine olive oil at home, it’s not advisable — the process is complex, requires specialized equipment, and involves chemical substances.

Refined Olive Oil Price

The price of refined olive oil can vary depending on factors such as quality, brand, and purchase location.

Generally, refined olive oil is cheaper than extra virgin olive oil because the production process is less costly.

In fact, most of the olive oils available on the market are refined varieties due to their lower price and wide availability.

However, price doesn’t always equal quality — it’s important to read labels carefully and choose products that guarantee authenticity and purity.

To summarize, refined olive oil can be a useful and affordable option for everyday cooking. However, whenever possible, choose extra virgin olive oil to enjoy its superior nutritional benefits and natural flavor.
