Understanding the Safe Daily Intake of Olive Oil
While extra virgin olive oil is praised for its health benefits, moderation is key, especially when drinking it directly. Most dietary recommendations suggest that a daily intake of 1 to 4 tablespoons (15-60 ml) is both safe and beneficial for most adults. The total amount, however, should always be viewed in the context of your entire diet and overall caloric intake, as olive oil is calorie-dense. The practice of drinking olive oil, while popular, offers no scientifically proven benefits over simply incorporating it into meals.
For example, studies supporting the health benefits of olive oil often refer to its use as a primary fat source within the Mediterranean diet, rather than as a supplement taken in large amounts. This means substituting less healthy saturated fats with olive oil, not simply adding more calories to your existing diet. Replacing butter, margarine, or other fats with olive oil in cooking and dressings is a sustainable way to increase intake without adding excessive calories.
Benefits of Drinking Olive Oil in Moderation
Incorporating a moderate amount of olive oil into your daily routine provides several health advantages, primarily due to its rich composition of monounsaturated fatty acids (MUFAs) and powerful antioxidants. These benefits are not exclusive to drinking olive oil, but are part of its regular consumption through various means.
- Heart Health: Regular intake of olive oil has been shown to reduce the risk of heart disease by lowering 'bad' LDL cholesterol levels and improving blood pressure.
- Anti-Inflammatory Effects: The polyphenols in extra virgin olive oil, like oleocanthal, have been found to have strong anti-inflammatory properties, similar to ibuprofen.
- Digestive Support: Some evidence suggests that a teaspoon of olive oil can help soften stools and relieve constipation, potentially helping to regulate gut microbiota.
- Antioxidant Boost: Olive oil provides a concentrated source of antioxidants, protecting cells from damage caused by free radicals.
Potential Risks of Overconsumption
Exceeding the recommended daily intake can lead to unwanted side effects. While not inherently dangerous in moderate quantities, olive oil is not without its risks when consumed in excess.
- Weight Gain: Olive oil is high in calories (approximately 120 calories per tablespoon). Consuming large amounts beyond your body's energy needs can lead to significant weight gain over time, offsetting other health benefits.
- Gastrointestinal Distress: For some individuals, drinking excessive olive oil, particularly on an empty stomach, can lead to nausea, diarrhea, and other digestive discomforts.
- Displacing Nutrients: Drinking too much olive oil might displace other nutrient-dense foods from your diet, such as vegetables, fruits, and whole grains. A balanced diet is more beneficial than relying on a single food for all health needs.
Comparing Different Intake Methods
| Consumption Method | Benefits | Potential Downsides | Best Practices |
|---|---|---|---|
| Drinking a 'Shot' | Concentrated dose of antioxidants and healthy fats. May aid digestion. | High calorie density; potential for digestive upset. No proven superiority over consuming with food. | Start with 1 teaspoon and do not exceed 1-2 tablespoons. Use high-quality Extra Virgin Olive Oil (EVOO). |
| Incorporating into Meals | Enhances nutrient absorption of other foods (e.g., tomatoes). Improves satiety. Offers flavor and is easy to integrate. | Can add calories quickly if not replacing other fats. | Use as a dressing, drizzle over finished dishes, or use for lower-temperature cooking. Ensure it fits into your overall fat and calorie goals. |
| Using in Cooking | Allows for replacement of less healthy saturated fats like butter. Adds flavor to dishes. | High-heat cooking can degrade some beneficial polyphenols in EVOO. | For high-heat cooking, use a more refined olive oil. Use EVOO for lower-heat applications and as a finishing oil. |
Conclusion
To answer the question of how much olive oil is safe to drink daily, the consensus among experts is that a moderate amount—typically between 1 to 4 tablespoons—is considered safe and beneficial as part of a balanced diet. While the popular trend of drinking 'shots' of olive oil exists, there is no scientific evidence to suggest this offers more health benefits than simply incorporating the oil into your food. The key is moderation and ensuring the oil complements, rather than replaces, other healthy foods in your diet. Opting for high-quality Extra Virgin Olive Oil (EVOO) provides the most nutrients. Ultimately, a balanced, Mediterranean-style diet that uses olive oil liberally in cooking and dressings remains the most recommended approach to reaping its full potential benefits without risking adverse effects from overconsumption.
Expert Perspective
"The benefits of olive oil are well-established within the context of a healthy diet, not as a solitary 'cure-all' supplement," says registered dietitian Marie Barone. "The 2020-2025 Dietary Guidelines for Americans recommends replacing saturated fats with healthy oils like olive oil, keeping total oil intake under 2 tablespoons a day for most 2,000-calorie diets. Drinking more than this can easily lead to excess calorie consumption, potentially leading to weight gain.". Barone emphasizes that the best approach is to focus on your overall eating pattern rather than any single food. For individuals with specific health concerns like diabetes or blood pressure issues, consulting a doctor or dietitian is essential, as olive oil can affect blood sugar and blood pressure levels.
- Listen to your body. Some people, particularly those with sensitive digestive systems, may experience discomfort when drinking olive oil on an empty stomach.
- Prioritize quality. Choose high-quality Extra Virgin Olive Oil (EVOO), which contains higher levels of beneficial compounds like polyphenols compared to more refined oils.
- Focus on the bigger picture. Think of olive oil as a healthy fat to be used within a balanced dietary framework, not as a magic bullet for health.
- Substitute, don't just add. Instead of simply adding tablespoons of olive oil to your day, replace less healthy fats with it to avoid excessive calorie intake.

How to incorporate olive oil safely into your routine
There are numerous ways to enjoy the benefits of olive oil without the potential drawbacks of overconsumption. By focusing on smart, moderate usage, you can make it a staple of your diet.
In Salad Dressings
Create a simple, healthy vinaigrette with extra virgin olive oil, balsamic vinegar, and herbs. This method not only enhances the flavor of your salads but also helps with the absorption of fat-soluble vitamins from the vegetables.
As a Drizzle for Finished Dishes
A high-quality EVOO is perfect for finishing dishes like soups, roasted vegetables, or pasta. This preserves its delicate flavor and potent antioxidant content that can be diminished by high heat cooking.
In Smoothies
For those who prefer a taste-free way to consume it, a tablespoon of olive oil can be blended into a smoothie. This is an easy way to get a dose of healthy fats without the strong flavor.
As a Bread Dipping Sauce
Enjoying olive oil with whole-grain bread is a classic and delicious way to consume it. For an extra treat, add some herbs, spices, or balsamic vinegar.
By following these practical tips and adhering to the recommended intake, you can confidently include olive oil in your daily life to support your overall health.
Important Considerations
Before making any major dietary changes, it's wise to consider your personal health profile and consult a healthcare professional. People with diabetes, for instance, should monitor their blood sugar closely when increasing olive oil intake, as it can lower blood sugar levels. Likewise, individuals on blood pressure medication should be aware that olive oil may have a blood pressure-lowering effect. Always remember that a single food, no matter how healthy, is not a miracle cure, but rather one component of a holistic approach to wellness.
By prioritizing moderation, choosing high-quality Extra Virgin Olive Oil, and integrating it thoughtfully into a balanced diet, you can enjoy its many benefits safely and effectively.
