Key Nutrients in Olive Oil (Per Tablespoon Serving)
Macronutrient Breakdown
One tablespoon (about 14 grams) of extra virgin olive oil provides:

Selecting and Storing Olive Oil for Maximum Freshness
To enjoy the best taste and nutritional value, choose extra virgin olive oil, which is minimally processed and richest in antioxidants. Look for oils packaged in dark glass bottles, as light exposure can degrade quality. Store olive oil in a cool, dark place and tightly seal the bottle after each use to preserve its flavor and nutrients. Ideally, use olive oil within six months of opening.
Points to Consider When Using Olive Oil
- Portion Awareness: Olive oil is calorie-dense, so moderate portions are key for those watching caloric intake.
