Olive oil has been a staple in many cuisines, particularly in Mediterranean cooking, for centuries. It’s prized for its distinct flavor, aroma, and potential health benefits. However, in recent years, some cooking experts and health enthusiasts have raised concerns about using olive oil for cooking, citing its potential drawbacks. In this article, we’ll delve into the world of olive oil and explore the pros and cons of using it for cooking.
The Chemistry of Olive Oil
To understand whether olive oil is bad to cook with, it’s essential to grasp its chemical composition. Olive oil is primarily composed of monounsaturated fats (MUFAs), which are considered a healthier type of fat. It also contains a small amount of polyunsaturated fats (PUFAs) and saturated fats. The fatty acid profile of olive oil is:
- Monounsaturated fats (MUFAs): 55-83%
- Polyunsaturated fats (PUFAs): 3-21%
- Saturated fats: 7-20%
Olive oil also contains various antioxidants, such as vitamin E and polyphenols, which contribute to its distinct flavor and aroma.
Smoke Point: The Critical Factor
One of the primary concerns about cooking with olive oil is its relatively low smoke point. The smoke point is the temperature at which an oil begins to break down and smoke, potentially leading to the formation of unhealthy compounds. Olive oil’s smoke point varies depending on its quality and production methods, but it generally ranges from 320°F (160°C) to 420°F (220°C).
In comparison, other cooking oils like avocado oil, grapeseed oil, and peanut oil have higher smoke points, making them more suitable for high-heat cooking. However, it’s essential to note that the smoke point is not the only factor to consider when evaluating an oil’s suitability for cooking.
The Risks of Cooking with Olive Oil
While olive oil can be a healthy choice, there are some potential risks to consider when cooking with it:

However, it’s crucial to note that the oxidation process can be slowed down by using high-quality olive oil, storing it properly, and cooking at moderate temperatures.
Formation of Acrylamide
Acrylamide is a potential carcinogen that can form when starchy foods are cooked at high temperatures, particularly when using olive oil. However, the International Agency for Research on Cancer (IARC) has classified acrylamide as “probably carcinogenic to humans,” and more research is needed to fully understand its effects.
Nutrient Destruction
Heat can also destroy some of the delicate nutrients found in olive oil, such as vitamin E and polyphenols. However, this can be mitigated by cooking at lower temperatures and using gentle heat.
The Benefits of Cooking with Olive Oil
Despite the potential risks, cooking with olive oil can also have several benefits:
