Key nutrients
- Monounsaturated Fatty Acids (MUFA) — Constitutes the majority of its lipid profile, predominantly as oleic acid, which helps lower LDL cholesterol.
- Vitamin E (Alpha-tocopherol) — A fat-soluble antioxidant that protects cell membranes from oxidative damage.
- Polyphenols — Bioactive compounds (such as oleuropein and hydroxytyrosol) that exhibit strong anti-inflammatory properties, particularly in extra virgin varieties.
