Olive Oil Basics

You get olive oil from grinding or pressing whole olives and collecting the oil that seeps out. You can use olive oil in all kinds of dishes. You can cook with it, drizzle it on bread, pasta, or salads, or use it as an ingredient in baked goods. Best of all, it comes with a whole host of health benefits.

Types of Olive Oil

Olive oil comes in one of three types, or grades: extra virgin, virgin, and refined (light). They’re labeled based on how much processing they go through before they’re bottled and sold. Refined olive oil is the most processed of the three.

Which Is Healthiest?

The olive oil that goes through the least amount of processing to make is extra virgin olive oil (EVOO). Because of this, EVOO has more nutrition than virgin or refined olive oils do. For example, it’s high in healthy plant nutrients called phytochemicals that may help fight cancer and heart disease. So to get the most from your olive oil, reach for the EVOO.

Boosts Heart Health

Large studies have shown that when you get more extra virgin olive oil in your diet, you lower your risk of getting heart disease. Active compounds in EVOO help lower blood pressure and keep your arteries from hardening.

Fights Inflammation

Inflammation in your body leads to chronic disease. Certain antioxidants in EVOO can reduce inflammation in your body in the same way that drugs such as ibuprofen do. The oleic acid in olive oil is an anti-inflammatory, too.

High in Antioxidants

Free radicals are unstable atoms in your body that damage your cells. Antioxidants are compounds that can help prevent or slow down that damage. EVOO is teeming with antioxidants that can lower your risk of disease.

Prevents Cancer

A Mediterranean diet favors plants over meat and is rich in olive oil. Researchers have found that people who eat this way  have a much lower risk of certain cancers, such as colorectal, endometrial, breast, pancreatic, and prostate cancers.

Boosts Your Brain

Another bonus of an olive-oil heavy Mediterranean diet: It can give your brain a boost. Studies show a menu that’s high in olive oil can help you think, understand, and remember better, and may even help ward off Alzheimer’s disease.
