Choosing the Best Olive Oil for Your Health and the Environment

Shopping for olive oils can be tricky. With so many different options on store shelves, it can be hard to know which one to choose. Before you put one into your cart, functional medicine doctor Mark Hyman, MD, says it's not just your health you'll want to factor into your decision—it's also the environment.

According to Dr. Hyman, the popularity of olive oil hasn't been great for the planet. "Intensive olive farming has led to widespread soil erosion and desertification (a process by which fertile land becomes desert) in Greece, Italy, Spain, and Portugal," he wrote on Instagram. "In addition to destroying fertile lands, large olive producers rely on massive amounts of pesticides and other chemicals, which pollute waterways. Because olive production occurs on such a large scale to meet the growing demand for oil, it also puts a lot of pressure on water supplies."

That's why he says it's better to purchase from companies that give you the best of both worlds—ones that are not only the most nutrient-rich but also sourced from small farms and well-managed production practices. And Amy Gorin, RDN, a plant-based registered dietitian in the New York City area, agrees.

"Extra-virgin olive oil is the highest quality olive oil you can buy. It has excellent flavor and odor and a free fatty acid content. It also has a lower level of oleic acid than other types of olive oils," she says. "When you’re purchasing olive oil, you can buy fair trade olive oil and also purchase your oil from a company that enforces sustainable growing practices. You also want to make sure that the oil is low in pesticides and chemicals."

The next time you go shopping, these are the best olive oils to buy, according to Dr. Hyman and Gorin.

“At Pasolivo, we hand-pick all of our olives which causes less bruising to the fruit and less stress to the tree than some other methods. We also process our olives within hours of coming off our trees in our own on-site olive mill. Olives have to be processed within 24 hours of coming off of the tree; otherwise, they start to ferment. Since we do not have to take the olives anywhere else, we reduce the risk of any defects that might be caused by time, weather, or transit,” Marisa Bloch Gaytan, Pasolivo’s master blender and level two olive oil sommelier, says.

How do you choose an extra virgin olive oil?

According to Marisa Bloch Gaytan, a master blender and level two olive oil sommelier of California-based olive oil company, Pasolivo, these are some of the top things you should look out for when buying EVOO:

1. Packaging

“You should look for olive oil that is in dark packaging. We paint our bottles black to completely block out the UV rays. Even dark glass packaging can let light in, so something that completely blocks it out is best,” Gaytan says. The delicate, healthy fats in olive oil are sensitive to heat and light; thus, dark-colored bottles help prolong their shelf life.

2. Smell

“Olive Oils should have a pretty strong smell. Whether it is green and grassy or more ripe and fruity, you should be picking up wonderful aromas from olive oil. If you do not smell much of anything, that is not a good sign,” she explains. So, make sure to take a nice long whiff before you add the oil to your dish.

3. Taste

According to Gaytan, EVOO should have a nice bitterness and pungency to it. “Bitterness is what you want to taste on your tongue and the sides of your mouth, and the pungency is that tickle you will get in the back of your throat that makes you want to cough. The pungency is those polyphenols at work that give you the health benefits of olive oil,” she adds.

How can I tell when buying olive oil that it is real and fresh?

When buying high-quality olive oil, Gaytan says you’ll want to make sure that it’s extra-virgin certified. “Some oils will list extra virgin on the label when they are not. It’s important to buy from a source that gets certified extra-virgin by a qualified organization.” However, she points out that if the certification is not listed on the bottle, you can visit the council websites, like the California Olive Oil Council or International Olive Oil Council, and find a list of certified oils.

Gaytan also says that you should opt for single-source olive oil whenever possible. “Some oils will list that they are from Italy, Spain, and Greece. While that sounds really romantic, all that means is the oils had to travel from each of those places before they were blended, bottled, and then transported for sale. All of this transporting can affect the quality and integrity of the oil,” she says. Plus, you should always buy bottles based on their harvest or best-by date. According to her, the sweet spot is within two years of the harvest date.

Does olive oil have to be refrigerated after it is opened?

According to Gaytan, the delicate fats in olive oil are sensitive to extreme conditions. The olive oil sommelier recommends storing olive oil in a dark, cool place, like a cupboard. She points out that you definitely shouldn’t put it in the fridge, which can cause the oil to solidify, which can break down the compounds in the oil and affect its quality over time. And you should also avoid storing oil near the stove or a window where it can be exposed to too much constant light and heat, which will also affect the oil’s quality.
