5 Crucial Reasons To Stop Cooking With Olive Oil

Are you aware that heating Olive Oil destroys many of its heart-healthy properties? It is often referred that saturated fats are the best fats to use when cooking.


This has to do with the molecular structure of oils. Saturated fats contain no double bonds so are not sensitive to heat, light or oxygen, unlike unsaturated fats. Unsaturated fats (vegetable oils) have double bonds, making them very sensitive to heat, light and oxygen. In addition, heating these types of oils will change their molecular structure, destroying a handful of the healthy properties.

Monounsaturated Fats In Olive Oil Are Not Heat Stable 

Olive Oil is made up of about 70-80% monounsaturated fat, in the form of oleic acid. As a result, this oleic acid is what gives Olive Oil a handful of its incredible health benefits such as improved insulin resistance, cancer-fighting properties, and improved heart health.

It is also these monounsaturated fats that give Olive Oil a low smoking point, making it unsuitable for temperatures above 250’F (121’C).

Heart Healthy Polyphenols In Olive Oil Are Seamlessly Damaged By Heat 

Olive Oil has phenolic compounds, mainly hydroxytyrosol and oleuropein, that are rich in antioxidant properties. These phenols, which work as antioxidants to preserve heart health, start to degrade at high heats.

Heating Olive Oil Helps Destroy Omega Fatty Acids

Olive Oil contains both Omega 3 and Omega 6 Fatty Acids. According to Dr. Mercola, omega-3 fats are “significant structural components of the cell membranes of tissues throughout the body and are especially rich in the retina, brain, and sperm, in which docosahexaenoic acid (DHA) constitutes 36.4% of total fatty acids”. 

These fatty acids are sensitive to heat and are easily destroyed when Olive Oil is heated.

Low Smoke Point = Breathing In Toxic Smoke

If an oil is heated beyond its smoke point, it gives off toxic smoke. Because Olive Oil has a low smoking point, generally, cooking with Olive Oil runs the risk of creating smoke that contains compounds that are harmful to human health. 

Many Olive Oils Are Not Real 

A handful of brands cut their Olive Oil with inexpensive oils such as soybean oil, canola oil, hazelnut oil and low grade olive oils.

A study by UC Davis in 2011 discovered that 73% of the 5 best selling imported brands of Olive Oil did not meet the international sensory standards for Extra Virgin Olive Oil set by European regulators.

This usually meaning that they could be adulterated or blended with other vegetable oils such as soy, corn, cottonseed, hazelnut, or canola oil.

What Is One To Do Next?

Olive Oilis a healthy and delicious oil. It is amazing in salad dressings and dips and can be drizzled over already cooked vegetables.
