Olives: Briny Bites Loaded with Heart-Healthy Monounsaturated Fat & Vitamin E
Ten medium olives (30 g) deliver 45 kcal, 4 g fat (75 % oleic acid), 1 g fiber and 12 % DV vitamin E—plus the signature Mediterranean umami-salt punch.
What Exactly Are Table Olives?
Olives are the fermented or brine-cured drupes of the evergreen **olive tree (*Olea europaea*)**. Fresh off the branch they’re inedibly bitter—curing transforms the phenolic compound **oleuropein** into a pleasantly savory fruit.
Common Varieties & Flavor Notes
- **Manzanilla (Spain)** – small green, buttery, often pimento-stuffed
- **Kalamata (Greece)** – purple-black, meaty, wine-like tang
- **Castelvetrano (Italy)** – bright green, sweet & mild
- **Arbequina (Spain)** – tiny, nutty, high oil content
Season peaks **October → January** but cured olives are shelf-stable all year.
