So what exactly is it in olive oil that makes it so healthy? Well, there's a number of chemical compontents that do your body good. But first it's important to understand...
In terms of the health benefits found in olive oil, Extra Virgin has far more of the good stuff than the lower grades. Refined grades like Pure Olive Oil, Refined (Light) Olive Oil and Olive Pomace Oil are going to have less (or debatably, none) of the healthy-for-you components. So let's look at the benefits of Extra Virgin Olive Oil in particular.
Polyphenols are a key component to olive oil, and are considered to be one of the best health benefits. Polyphenols furnish the immune system, protect us from heart diseases and display anticancer activity as they act as free radicals traps. They protect olive oil from oxidative damage and they contribute to its superior oxidative stability among other edible oils. They also affect its taste, giving it a distinctive bitter flavor. ²
There are a number of different types of polyphenols, including oleuropein, tyrosol, hydroxytyrosol, oleocanthal and oleacein. Each are considered extremely strong antioxidants, and are linked to a number of different benefits, including
Vitamin E is a good example of one of these antioxidants. Vitamin E is a significant compontent of olive oil, and is thought to decrease the risk of many cancers.
This is one of the important polyphenols that produces a stinging feeling in the back of your throat in especially peppery or bitter olive oils. Though that taste is a learned one for some people, but the properties of this component are known to be some of the best parts of the oil for you. This component mimics the effects of ibuprofen, by reducing inflammation. This has a particular effect on long term inflamatory illnesses, including certain cancers and is considered beneficial in the prevention of Alzheimers.
The sterols in Extra Virgin Olive Oil are known to decrease the blood cholesterol levels and help inhibit cholestrol absorption in the small intestine. Sterols have also been shown to act as anti-inflammatory, anti-bacterial, anti-fungal, anti-ulcerative, anti-oxidant and anti-tumor component. ²
Squalene is a component believed to prevent certain types of cancer and is beneficial for patients with heart disease and diabetes. Olive oil has the highest concentration of squalene compared to other edible oils (for example, olive oil has 5-20x more squalene than found in corn oil).
Fat is a vital compontent of a healthy diet. Though the word "fat" is looked down upon in our day and age, not all fats are actually bad for you. In fact, it is the type of fat that is important.
Monounsaturated fats (as opposed to saturated or polyunsaturated fats) are commonly found in nuts, seeds and olive oil and are considered to be a better-for-you fat. One reason is because monounsaturated fat doesn't oxidize in the body, while polunsaturated fat does. Many agree that these monounsaturated fats have the following benefits for a healthy body:
