The Power of Polyphenols: Why Extra Virgin Olive Oil is a Superfood

March 12, 2025

If you’ve ever heard about the health benefits of extra virgin olive oil (EVOO), chances are you’ve come across the term polyphenols. But what exactly are they, and why do they matter?


Polyphenols are naturally occurring plant compounds found in a variety of foods, including fruits, vegetables, herbs, dark chocolate, and—most notably—extra virgin olive oil. These antioxidant-rich compounds play a crucial role in reducing inflammation and protecting cells from oxidative stress, which is linked to aging, environmental factors, diet, and overall lifestyle choices.

Why Are Polyphenols So Important?


Polyphenols serve as powerful antioxidants, helping the body combat cellular damage caused by free radicals. Among the many polyphenols found in EVOO, oleocanthal stands out for its unique ability to act similarly to ibuprofen, offering natural anti-inflammatory properties. Research suggests that diets rich in polyphenol-packed EVOO can help support overall long-term health by reducing inflammation—a key factor in preventing chronic diseases.


What Affects the Polyphenol Levels in Olive Oil?


Not all extra virgin olive oils are created equal. The polyphenol content in EVOO varies based on several key factors:


  • Harvest Timing – Early-harvest olives typically contain higher concentrations of polyphenols compared to later-harvest olives. Choosing early-harvest EVOO ensures maximum antioxidant benefits.
  • Olive Variety – Some olive varieties are naturally richer in polyphenols than others. One of the best examples is the Koroneiki olive, a small but mighty green olive renowned for its high polyphenol content and exceptional flavor profile.


How Does High-Quality EVOO Compare to Grocery Store Olive Oil?


The difference between premium extra virgin olive oil and most store-bought brands is staggering. Many commercial olive oils undergo processing and refining, which significantly reduces their polyphenol content—limiting the very benefits that make EVOO a nutritional powerhouse.


Choosing the Right EVOO for Your Kitchen


For those looking to incorporate high-polyphenol extra virgin olive oil into their daily routine, it’s essential to choose the right type for the right purpose:


  • For Drizzling, Dipping & Finishing – A bold, aromatic EVOO is best used raw to preserve its full spectrum of antioxidants and flavor. Use it on salads, vegetables, fresh bread, and as a finishing touch on dishes.
  • For Cooking, Roasting & Sautéing – A high-quality EVOO designed for everyday cooking should offer a balanced flavor and a high smoke point to withstand heat while still delivering exceptional taste and health benefits.


By making extra virgin olive oil a staple in your kitchen, you’re not just elevating your meals—you’re investing in your long-term health.
