What Is Olive Oil?
Olive oil is derived from the fruit of the olive tree, native to the Mediterranean region. It is made by pressing olives and extracting their oil, a process that has been around for thousands of years. The type of olive oil you choose can make a significant difference in its nutritional value and health benefits.
Types of olive oil:
Extra virgin olive oil (EVOO): The highest quality, unrefined olive oil. It is pressed with cold water, preserving its natural antioxidants and heart-healthy fats.
Virgin olive oil: Slightly lower in quality than extra virgin, it is also extracted without chemical processing.
Refined olive oil: A processed version of olive oil that has had some of its nutritional properties removed.
Olive pomace oil: Extracted from the pulp of the olives left after pressing, often used in commercial kitchens due to its lower price.
Of these, extra virgin olive oil is the healthiest and most recommended due to its abundance of health-promoting compounds.
Olive Oil Nutrition Profile
Olive oil is composed of 100% fat, but not all fats are the same. The main fat found in olive oil is monounsaturated fat, specifically oleic acid, which makes up about 73% of the oil's total content. This is key to olive oil's health benefits, especially in relation to heart health.
Nutrients in Olive Oil:
Monounsaturated fats (MUFA): These are "good fats" that help lower bad cholesterol (LDL) levels.
Polyphenols: Antioxidants that fight oxidative stress and inflammation, both of which contribute to heart disease.
Vitamin E: A powerful antioxidant that helps maintain heart health.
Vitamin K: Key for blood clotting and bone health.
How Olive Oil Helps Lower Heart Disease Risk
Heart disease is a complex condition that develops over time due to a variety of factors, including poor diet, sedentary lifestyle, high blood pressure, and cholesterol imbalances. Several studies have shown that regular consumption of olive oil, especially extra virgin olive oil, can significantly lower the risk of heart disease. Here's how:
1. Lowers LDL cholesterol
Low-density lipoprotein (LDL) cholesterol, often called "bad cholesterol," plays a key role in the buildup of plaque in the arteries, leading to atherosclerosis and heart attacks. Olive oil, especially rich in oleic acid, helps reduce LDL levels while maintaining or even increasing HDL (good) cholesterol.
2. Lowers blood pressure
A major risk factor for heart disease is High blood pressure (hypertension) is a. Olive oil has been shown to lower blood pressure due to its rich content of polyphenols and monounsaturated fats. In a study published in the journal Hypertension, individuals who consumed extra virgin olive oil daily showed a significant drop in both systolic and diastolic blood pressure, reducing the risk of cardiovascular complications.
3. Reduces inflammation
A silent contributor to many diseases is chronic inflammation, including heart disease. The high concentration of antioxidants in olive oil, particularly oleocanthal, acts as an anti-inflammatory agent. It works similar to ibuprofen in reducing inflammation, which is important in protecting blood vessels and heart tissue from damage.
4. Improves endothelial function
The endothelium is the thin membrane lining the heart and blood vessels, which plays a key role in vascular health. Dysfunction of this lining is one of the earliest stages of atherosclerosis. Studies show that olive oil improves endothelial function, helping arteries dilate properly and reducing the risk of artery blockages.
5. Prevents oxidative damage
Oxidative stress, caused by an imbalance of free radicals and antioxidants in the body, can lead to the oxidation of LDL cholesterol. This oxidized LDL is more likely to accumulate in the arteries, leading to plaque buildup and heart disease.
The polyphenols in extra virgin olive oil provide a powerful antioxidant defense, protecting LDL cholesterol from oxidation and maintaining heart health. Mediterranean Diet and Heart Health

| The Mediterranean Diet |
A landmark study, known as the PREDIMED trial, followed more than 7,000 individuals at high risk of heart disease. Participants who followed a Mediterranean diet supplemented with extra virgin olive oil experienced a 30% reduction in heart attack, stroke, and cardiovascular mortality compared with those who stayed on a low-fat diet. This dramatic result has made olive oil a central component of heart-healthy eating recommendations around the world.
How much olive oil should you consume for heart health?
According to the American Heart Association and many health experts, consuming about 2 tablespoons (20–30 grams) of olive oil per day may provide heart-healthy benefits. The oil can be drizzled on salads, used in cooking, or even spooned over.
However, it's important to note that olive oil is calorie-dense, so it should be consumed in moderation. Using it as a substitute for less healthy fats like butter, margarine, or refined oils can increase its benefits without adding extra calories.
Cooking With Olive Oil: Is It Safe?
There's some debate over whether or not olive oil is safe to cook with, as it has a lower smoke point than other oils like canola or vegetable oil. Extra virgin olive oil has a smoke point of around 350–410°F (175–210°C), which is suitable for most cooking methods, including sautéing, roasting, and baking.
Research has shown that even when heated, extra virgin olive oil retains most of its nutritional value, including its high levels of antioxidants and heart-healthy fats. Just avoid using it for frying at high temperatures to preserve its beneficial compounds.
Tips for combine olive oil into your diet
Olive oil is incredibly versatile and can be used in countless ways in the kitchen. Here are some ideas:
Salad dressings: Mix olive oil with balsamic vinegar, lemon juice or herbs for a heart-healthy salad dressing.
Cooking: Use olive oil to roast vegetables, meats and fish for added flavor and health benefits.
Baking: Use olive oil in place of butter in baked goods like cakes and muffins for a healthier option.
Drizzling: Add even more depth of flavor by drizzling extra virgin olive oil over roasted vegetables, pasta or even pizza.
Dips: Create a simple dip with olive oil and herbs that's perfect for dipping whole grain bread.
