Recently I asked myself a rather rare question: What Is High-Polyphenol Olive Oil? And I found out that olive oil contains low polyphenols and I want to share this information. Polyphenols are natural compounds found in plants that have unique antioxidant and anti-inflammatory properties. In olive oil, they determine the taste, aroma and beneficial qualities. Olive oils that are high in polyphenols have a stronger flavor and are often savory. Its benefits include antioxidant protection, reducing inflammation, supporting heart health, and slowing cellular aging.
