Calories & Fat Profile

One tablespoon of olive oil has about 120 calories, coming almost entirely from fat. Roughly 70–75% of these fats are monounsaturated (oleic acid), linked with heart-friendly dietary patterns. EVOO also contains small amounts of polyunsaturated fats and minimal saturated fat—making it a healthier option than butter or margarine. See also our Olive Oil vs Butter guide.

Polyphenols & Antioxidants

Polyphenols are plant compounds that act as antioxidants, protecting the oil and your body from oxidation. High-polyphenol EVOO has a distinct peppery and slightly bitter taste—these sensations are markers of antioxidant presence. According to research from the National Institutes of Health (NIH), olive oil polyphenols may contribute to protecting blood lipids from oxidative stress when consumed regularly as part of a balanced diet.
