Optimal Daily Extra Virgin Olive Oil (EVOO) Consumption
To achieve health results, the consensus across medical studies and health organizations is a daily consumption of 1 to 2 tablespoons (approximately 15 ml to 40 ml) of Extra Virgin Olive Oil (EVOO).
However, the exact amount required depends on the specific health benefit you are seeking and the quality (polyphenol content) of the oil.
1. General Recommendation: 1–2 Tablespoons
For general health maintenance and disease prevention, sources typically recommend 1 to 2 tablespoons daily.
-
FDA Guideline: The FDA suggests consuming 1.5 tablespoons (about 22 ml) daily to reduce the risk of heart disease, provided it replaces sources of saturated fat rather than adding to total caloric intake 3, 4.
-
European Food Safety Authority (EFSA): To claim protection of blood lipids from oxidative stress, the EFSA recommends a daily intake of 20 grams (approx. 1.5 tablespoons) of olive oil containing at least 5 mg of hydroxytyrosol and its derivatives.
2. The "Quality Over Quantity" Rule
Recent research indicates that you may need less oil if it is rich in polyphenols (antioxidants).
-
High-Phenolic Efficiency: A clinical trial comparing different doses found that a lower dose of 8 grams (less than 1 tablespoon) of high-phenolic EVOO was more effective at improving lipid profiles (reducing total cholesterol and oxidized LDL) than a higher dose of 20 grams of low-phenolic oil 8, 9.
-
Polyphenol Calculation: If consuming a standard supermarket oil with lower polyphenol levels (e.g., ~250 mg/kg), you may need 3 tablespoons to achieve the same therapeutic antioxidant effect that 2 tablespoons of a high-phenolic oil (e.g., >644 mg/kg) would provide 10.
3. Dosage for Specific Health Goals
Different studies have utilized varying amounts to achieve specific clinical outcomes:
-
Constipation Relief: A smaller dose of roughly 1 teaspoon (4 ml) daily has been found effective for softening stools and relieving constipation, performing as well as mineral oil in some trials 11, 12.
-
Cardiovascular Protection: The landmark PREDIMED study, which proved significant reduction in cardiovascular events, utilized a higher intake of at least 4 tablespoons (60 ml) daily as part of a Mediterranean diet 13, 14.
-
Bone Health: Significant improvements in bone density were observed in women consuming more than 18 grams (approx. 20 ml) of olive oil daily.
4. Important Consumption Warnings
-
Caloric Density: Olive oil is calorie-dense, containing approximately 119–120 calories per tablespoon 17, 18. To avoid weight gain, it should replace other fats (like butter or seed oils) rather than be added to an already high-calorie diet.
-
Digestive Limits: Consuming more than 2 tablespoons at once, especially on an empty stomach (the "shot" method), can lead to nausea, heartburn, cramping, or diarrhea.
-
Absorption Synergy: While drinking it raw is popular, consuming EVOO with food (such as tomatoes) can significantly increase the absorption of disease-fighting antioxidants.
