Study Examines Heart Health Effects of Reducing Extra Virgin Olive Oil Consumption
Recent Study Results on EVOO and Heart Health
Scientific studies confirm that extra virgin olive oil (EVOO) plays a role in reducing the risk of heart disease. Both large-scale population studies and clinical trials highlight how regular consumption of EVOO can improve cardiovascular health markers and lower heart disease risk.
Population Studies on EVOO Use
One major study followed 92,383 U.S. adults over a span of up to 28 years. Published in the Journal of the American College of Cardiology in 2022, this research from the Harvard T.H. Chan School of Public Health utilized data from the Nurses' Health Study and the Health Professionals Follow-up Study. Findings revealed that participants who consumed more than ½ tablespoon of olive oil daily had a 19% lower risk of cardiovascular-related death compared to those who rarely or never consumed olive oil. Additionally, replacing 10 grams of margarine with olive oil each day was linked to a 13% lower risk of overall mortality.
A separate meta-analysis of 13 studies found that every 5-gram increase in daily olive oil consumption was associated with a 4% reduction in cardiovascular disease risk. Higher consumption levels showed even more benefits, with risk ratios of 0.85 for cardiovascular disease and 0.83 for all-cause mortality. However, the benefits seemed to level off at around 20 grams per day, suggesting this as an optimal daily intake. The study also noted a rise in olive oil consumption in the U.S., from 1.6 grams per day in 1990 to approximately 4 grams per day in 2010.
These long-term findings are supported by clinical trials that show how EVOO can deliver short-term cardiovascular benefits.
Clinical Trials on EVOO and Heart Disease Markers
Controlled trials have demonstrated that regular EVOO consumption can lead to noticeable improvements in heart health markers like blood pressure and cholesterol levels in just a few weeks. For instance, consuming two tablespoons of EVOO daily has been shown to improve blood pressure and both HDL ("good") and LDL ("bad") cholesterol levels within three weeks.
The PREDIMED trial in Spain, which involved over 7,000 participants at high risk for cardiovascular disease, revealed that those who consumed 4 tablespoons of EVOO daily experienced a 30% reduction in major cardiovascular events. They also saw reduced risks of conditions like atrial fibrillation, diabetes, breast cancer, and neurocognitive decline.
Additionally, a 2023 study published in the European Journal of Clinical Nutrition found that individuals consuming 1½ tablespoons of EVOO daily were 57% less likely to die from cardiovascular disease compared to those who consumed none. This aligns with earlier research showing that even modest daily intake of EVOO is linked to lower all-cause mortality. The heart-health benefits of EVOO stem from its ability to reduce blood pressure, lower LDL cholesterol, decrease inflammation, and boost HDL cholesterol levels.
How EVOO Supports Heart Health
Extra virgin olive oil (EVOO) plays a key role in promoting heart health through a combination of beneficial actions. By understanding how it works, we can see why it’s such an effective addition to a heart-healthy lifestyle. One of its standout benefits lies in how it influences cholesterol levels, which we’ll explore below.
Effects on Cholesterol Levels
EVOO is rich in monounsaturated fats, especially oleic acid, which makes up 55–83% of its composition. This helps lower LDL (often called "bad cholesterol"), increase HDL ("good cholesterol"), and prevent the oxidation of LDL - a critical factor in the development of atherosclerosis.
A 2019 review of 27 studies revealed that olive oil not only reduces total cholesterol, LDL, and triglycerides but also boosts HDL more effectively than other plant-based oils. This is particularly important as high cholesterol impacts roughly 38% of adults in the U.S.. Additionally, the FDA has acknowledged that consuming around 2 tablespoons (23 grams) of olive oil daily may lower the risk of coronary heart disease. As Dr. Frank Hu from Harvard T.H. Chan School of Public Health noted:
"Olive oil is the hallmark of the Mediterranean diet, and its link to lower mortality is well established in southern European countries. But this is the first long-term study to show such a health benefit here in the U.S."
Beyond its impact on cholesterol, EVOO's polyphenols also contribute significantly to cardiovascular health.
Anti-Inflammatory and Antioxidant Properties
EVOO is packed with polyphenols, such as hydroxytyrosol and oleocanthal, which deliver strong anti-inflammatory and antioxidant effects. The polyphenol content in EVOO ranges from 50 to 1,000 mg per kilogram, with virgin olive oils typically offering 150–400 mg/kg, compared to negligible amounts in refined oils. These compounds help neutralize free radicals, bind harmful metals, and enhance the body’s natural antioxidant defenses.
The European Food Safety Authority has highlighted that "polyphenols in olive oil contribute to the protection of blood lipids from oxidative stress". These polyphenols also reduce inflammation by inhibiting NF-kB and lowering inflammatory markers like interleukin-1, TNF-α, and MCP-1. Oleocanthal, in particular, mimics the anti-inflammatory effects of ibuprofen by targeting COX-1 and COX-2 enzymes.
Other Heart Health Benefits
The benefits of EVOO don’t stop at cholesterol and inflammation. It also supports heart health by improving blood pressure and vascular function. EVOO increases nitric oxide availability, promoting vasodilation, which helps lower blood pressure. Long-term use has been linked to reductions in both systolic and diastolic blood pressure. Even a modest 2 mmHg drop in blood pressure can reduce the risk of coronary heart disease by 6%, stroke by 10%, and heart attack by 15%.
EVOO has also been shown to enhance vascular function, as evidenced by improved Flow-Mediated Dilation and reduced arterial wall thickening in those consuming over 34 grams daily. Additionally, it may reduce the risk of blood clots by preventing platelet activation, which is crucial in avoiding heart attacks and strokes.
These combined effects make extra virgin olive oil a powerful ally in maintaining a healthy heart and should be considered an essential part of any heart-conscious diet.

Adding EVOO to a Heart-Healthy Diet
Extra virgin olive oil (EVOO) has well-documented benefits for heart health, and incorporating it into your daily meals can be a simple yet effective way to support cardiovascular wellness. Knowing how much to use and how to include it in your cooking can make a big difference.
Daily EVOO Amounts
Studies highlight that consuming 1 to 2 tablespoons (14–23 grams) of EVOO daily can significantly lower the risk of heart disease. Even smaller amounts, like just over ½ tablespoon, have been associated with a 19% reduction in the risk of cardiovascular-related death. Swapping out just 5 grams (roughly 1/3 of a tablespoon) of saturated fat for olive oil can lower the risk of cardiovascular disease and coronary heart disease by 5–7%. Registered dietitian Julia Zumpano suggests consuming 1 to 4 tablespoons per day, depending on your caloric needs and health goals. Interestingly, both higher consumption (around 4 tablespoons) and lower consumption (less than a teaspoon) of EVOO have been linked to reduced LDL cholesterol levels. The key is finding the right balance for your lifestyle and health objectives.
Ways to Use EVOO in Daily Cooking
EVOO's flexibility in the kitchen makes it easy to use in a variety of dishes while retaining its heart-healthy properties. Its monounsaturated fats remain stable even when heated, making it a great choice for sautéing, roasting, and grilling.
For maximum antioxidant benefits, try using EVOO raw. Whisk it with red wine vinegar or lemon juice to create a simple salad dressing, adding minced shallots or garlic, salt, and pepper for extra flavor. Drizzle it over sliced tomatoes with a sprinkle of sea salt, fresh basil, and black pepper to enhance both taste and nutrient absorption. When cooking, EVOO works well for sautéing vegetables, as a marinade base for meats or fish, or for tossing with vegetables before roasting.
Another effective way to incorporate EVOO is by replacing less healthy fats like butter, sour cream, or mayonnaise. These substitutions can help reduce cardiovascular risk by 5–7%. For cooking, experts recommend heating EVOO only until it shimmers to preserve its beneficial properties.
EVOO not only supports heart health but also elevates the flavor of your meals. As registered dietitian Julia Zumpano explains:
"Part of the point of olive oil eating is the pleasure and enjoyment of it. It adds so much great flavor to food".
Why High-Quality EVOO Matters for Heart Health
Not all extra virgin olive oils (EVOOs) are created equal when it comes to supporting heart health. Differences in how they’re processed, their phenolic content, and even how they’re stored can significantly influence their cardiovascular benefits. The way EVOO is made plays a big role in preserving the compounds that are known to promote heart wellness.
What Sets Ultra Premium EVOO Apart
Ultra premium EVOO stands out because it contains a higher concentration of heart-friendly compounds. For example, the cold-pressing process helps retain key phenolics, which are essential for heart health. Advanced methods like de-stoning can also help preserve higher levels of oleocanthal, a compound linked to anti-inflammatory effects.
To qualify as high phenolic EVOO (HP-EVO), the oil must contain at least 250 mg of polyphenols per kilogram. Additionally, the European Food Safety Authority allows health claims for olive oils that provide a minimum of 5 mg of hydroxytyrosol and its derivatives per 20 g serving. Compared to other oils, EVOO often contains 3 to 6 times more secoiridoids, a group of beneficial compounds.
Freshness is another critical factor. Over time, the antioxidants and bioactive compounds in EVOO naturally break down, reducing its effectiveness. Consuming about 50 g of fresh extra virgin olive oil daily - which typically supplies around 10 g of oleocanthal - can offer anti-inflammatory benefits similar to 10% of the low-dose ibuprofen used for pain relief.
Proper storage also plays a big role in preserving the oil’s heart-protective properties. Controlled conditions can help maintain its antioxidant levels. As Rob McGavin, co-founder and chairman of Boundary Bend, explains:
"Antioxidants are called antioxidants because they sacrifice themselves to keep the oil fresh. When the oil comes under pressure from light, heat and oxygen, the antioxidants just keep sacrificing themselves."
These factors are essential for ensuring EVOO delivers maximum cardiovascular benefits.
