Is Olive Oil a Seed Oil? What You Need to Know

19 July, 2025 admin 0 Comments 1 category

Understanding what qualifies as a seed oil is essential to making informed choices about the types of fats you consume. In recent years, interest in healthy fats has skyrocketed—fueled by concerns over processed foods, inflammation, and metabolic health. One major source of confusion lies in differentiating olive oil from seed oils.

Is olive oil a seed oil? The short answer is no—but the reasons why are more nuanced and fascinating than you might think. In this post, we’ll explore the botanical definitions, extraction methods, nutritional differences, and health implications of olive oil and seed oils, helping you make educated decisions in the kitchen and beyond.

What Are Seed Oils?

Seed oils, as the name implies, are extracted from the seeds of various plants. These oils have become a staple in modern food processing due to their low cost, long shelf life, and neutral flavor. But not all oils are created equal—and the classification of “seed oil” extends beyond just its source. To better understand where olive oil stands, let’s examine what seed oils actually are.

Definition and Common Examples

Seed oils are vegetable oils derived from the pressed seeds of plants. These oils are often high in polyunsaturated fatty acids (PUFAs)—especially omega-6 fatty acids. Excess consumption of omega-6 fats, when not balanced by omega-3s, has been linked to inflammation and chronic disease.

Some of the most common seed oils include:

Soybean oil
Sunflower oil
Corn oil
Canola oil (from the rapeseed plant)
Cottonseed oil
Grapeseed oil
Safflower oil

Did you know? Soybean oil is the most widely consumed oil in the United States, making up over 50% of total edible oil consumption.

These oils are prevalent in ultra-processed foods like salad dressings, margarine, packaged snacks, and fast food—making them hard to avoid in the Standard American Diet.

How Are Seed Oils Made?

Most commercial seed oils undergo intensive industrial processing to be suitable for consumption. This typically involves:

Mechanical pressing followed by chemical solvent extraction (commonly using hexane, a petroleum-derived chemical).
Degumming, which removes phospholipids and impurities.
Neutralization, involving sodium hydroxide to remove free fatty acids.
Bleaching, to remove color and oxidized compounds.
Deodorization, using high heat to strip undesirable smells and flavors.

Here’s a comparison of typical processing steps for seed oils vs. extra virgin olive oil:

Processing Step	Seed Oils (e.g., Soy, Corn)	Extra Virgin Olive Oil
Solvent Extraction	✅ Yes (hexane)	❌ No
High-Heat Refining	✅ Yes	❌ No
Bleaching & Deodorizing	✅ Yes	❌ No
Cold-Press Mechanical	❌ Rare	✅ Yes
Nutrient Retention	❌ Low	✅ High

This high-heat and chemical processing not only strips away many of the natural antioxidants in seed oils but may also produce oxidized fats and other harmful byproducts such as trans fats in small amounts. These compounds have been linked to inflammation, heart disease, and cellular damage.

Expert Insight:
“Most seed oils are not just neutral carriers of calories—they are biochemically active in the body, influencing inflammation and cellular signaling.”
— Dr. Cate Shanahan, author of “Deep Nutrition”

In contrast, olive oil—especially in its extra virgin form—undergoes minimal processing, preserving its bioactive compounds, taste, and health-promoting properties.

This wraps up the first section of the blog post.

“What Is Olive Oil Made From?“

Let me know when to proceed!

What Is Olive Oil Made From?

To understand whether olive oil is a seed oil, we need to start with the basics: where it comes from. Unlike seed oils, which are derived from the seeds of plants, olive oil is extracted from the fruit of the olive tree (Olea europaea). This fundamental difference in origin has major implications for its classification, processing, and health impact.

The Source: Fruit vs. Seed

Olives are classified as drupes, or stone fruits—just like cherries, peaches, and plums. When producing olive oil, the oil is extracted from the flesh of the olive, not from the seed or pit. This makes olive oil a fruit oil, not a seed oil.

By contrast, seed oils (like sunflower or canola) are extracted directly from the seeds of plants, which are typically tiny, hard, and oil-rich structures that require intensive processing to yield oil.

Key Differences Between Olive Oil and Seed Oil Sources

Characteristic	Olive Oil	Seed Oil
Source	Olive fruit (flesh)	Seeds of plants
Botanical Category	Fruit oil	Seed oil
Common Examples	Extra virgin olive oil	Canola, sunflower, soybean, corn oil
Contains Seed Extract?	No (made from olive flesh)	Yes

This difference in plant anatomy means that olive oil retains more natural flavors, nutrients, and antioxidants than seed oils, especially when processed using traditional cold-pressing techniques.

Cold-Pressed vs. Refined Olive Oil

There are several grades of olive oil on the market, each with varying degrees of processing. The most beneficial type is extra virgin olive oil (EVOO). It is:

Cold-pressed: extracted mechanically without heat or chemicals.
Unrefined: it has not been subjected to industrial refinement processes.
Nutrient-rich: contains high levels of polyphenols, tocopherols (vitamin E), and oleic acid.

In contrast, refined olive oils (often labeled “pure” or “light”) undergo more processing to remove defects, which diminishes nutritional value. These refined versions are more stable for high-heat cooking but lack the antioxidant content of EVOO.

So, if you’re asking “Is olive oil a seed oil?”, this section should make it clear:

No, olive oil is not a seed oil. It is a fruit oil, mechanically extracted from the flesh of the olive fruit, without needing the high-heat or chemical methods used for seed oils.

This botanical and mechanical distinction sets olive oil apart from nearly every seed oil on the market, and it forms the foundation of its well-established health benefits and culinary superiority.

Is Olive Oil Technically a Seed Oil?

The classification of olive oil has sparked debate in nutrition circles, food blogs, and even scientific discussions. To answer the question clearly: no, olive oil is not technically a seed oil. But to fully understand why, we need to look at botanical definitions, extraction methods, and culinary classifications.

Botanical Classification

From a botanical perspective, seed oils come from seeds, while fruit oils come from the flesh of fruits. The olive is a fruit, and the oil is extracted primarily from its mesocarp—the soft, fleshy part that surrounds the seed. This makes olive oil a fruit oil, not a seed oil.

To illustrate this, consider the following classification table:

Oil Type	Source Plant Part	Category
Olive Oil	Olive fruit flesh	Fruit Oil
Canola Oil	Rapeseed	Seed Oil
Sunflower Oil	Sunflower seed	Seed Oil
Avocado Oil	Avocado flesh	Fruit Oil
Grape Seed Oil	Grape seeds	Seed Oil

As you can see, oils like olive and avocado are grouped separately from oils like canola or sunflower, which are classic examples of seed oils.

Is Olive Oil Processed Like Seed Oils?

Another reason olive oil is often wrongly grouped with seed oils is because both can be used for cooking. But their processing methods differ dramatically.

Seed oils are almost always refined, using a combination of chemical solvents, high heat, and deodorization processes to make them palatable and shelf-stable. In contrast, extra virgin olive oil is made by mechanical pressing, with no chemical intervention or high heat.

In short:

Seed oils = industrial, chemically refined.
Olive oil (especially EVOO) = natural, cold-pressed.

This stark difference affects not just the classification, but also the nutritional value and health impact of each oil.

Why the Confusion?

Many consumers—and even some food manufacturers—conflate olive oil with seed oils because of loose usage of the term “vegetable oil.” Technically, both seed and fruit oils fall under the “vegetable oil” category since they come from plants. However, this grouping is too broad to be meaningful, especially when considering health implications.

Key Clarification:

“Vegetable oil” is a broad term for plant-derived oils.
“Seed oil” is a more specific subset of vegetable oils derived exclusively from seeds.
Olive oil is a vegetable oil, but not a seed oil.

Summary: Why Olive Oil Is Not a Seed Oil

Let’s recap the major reasons why olive oil is not a seed oil:

Botanical Origin: Olive oil comes from the fruit of the olive tree, not seeds.
Processing Method: Olive oil is cold-pressed without industrial chemicals.
Nutritional Profile: Olive oil is high in monounsaturated fats and antioxidants, unlike most seed oils.
Culinary Classification: Olive oil has long been classified separately from seed oils due to its flavor, use, and extraction process.

So, to return to the central question of this article—Is olive oil a seed oil?—the evidence is overwhelmingly clear:

Olive oil is not a seed oil by botanical, chemical, or culinary standards. It is a fruit oil, extracted in a traditional, natural process that preserves its healthful properties.

Nutritional Differences Between Olive Oil and Seed Oils

One of the most important reasons for distinguishing between olive oil and seed oils lies in their nutritional profiles. The type of fat you consume plays a key role in inflammation, heart health, cellular function, and disease prevention.

So when asking, “Is olive oil a seed oil?”, the answer also depends on whether it behaves like one in the body. And the answer, again, is no—because olive oil and seed oils differ significantly in fat composition, nutrient density, and health effects.

Fatty Acid Composition: Olive Oil vs. Seed Oils

Let’s start with the types of fats each oil contains. Fats are broadly divided into:

Monounsaturated fats (MUFA) – heart-healthy, stable at cooking temperatures
Polyunsaturated fats (PUFA) – unstable at high heat, especially omega-6 fatty acids
Saturated fats – stable, but often controversial in modern dietary guidelines

Here’s a comparison of common oils:

Oil Type	Monounsaturated Fat (%)	Polyunsaturated Fat (%)	Saturated Fat (%)
Extra Virgin Olive Oil	73	11	14
Canola Oil	63	28	7
Sunflower Oil	20	69	11
Soybean Oil	24	61	15
Corn Oil	27	58	13

Key Insight:

Olive oil is rich in monounsaturated fat, specifically oleic acid, a compound associated with reduced inflammation, improved heart health, and oxidative stress protection.
Seed oils are high in polyunsaturated fats, especially omega-6 fatty acids, which can promote inflammation when consumed in excess and out of balance with omega-3s.

Why Omega-6 Dominance Is a Problem

Historically, humans consumed omega-6 and omega-3 fats in a 1:1 ratio. Today, the modern diet skews this balance toward 20:1 or higher—largely due to processed foods loaded with seed oils. This imbalance is associated with:

Increased inflammatory markers
Higher risk of heart disease
Possible links to autoimmune conditions, obesity, and even cancer

A study published in the journal Biomedicine & Pharmacotherapy (2020) found that diets high in omega-6 PUFAs, such as linoleic acid from seed oils, may contribute to chronic inflammation and metabolic dysfunction.

Antioxidants and Polyphenols in Olive Oil

One of olive oil’s key nutritional advantages is its abundance of antioxidants and polyphenols, particularly in extra virgin olive oil. These compounds have been shown to:

Fight oxidative stress
Reduce inflammatory signaling
Lower blood pressure and LDL cholesterol
Support brain health and memory

Here are some of the most potent bioactive compounds in olive oil:

Oleocanthal – has anti-inflammatory effects similar to ibuprofen
Hydroxytyrosol – one of the most powerful antioxidants found in nature
Squalene – supports skin health and cellular regeneration
Vitamin E (tocopherol) – protects cell membranes from oxidation

Seed oils, due to their refining processes, typically lack these protective compounds. During high-heat extraction and deodorization, these fragile molecules are destroyed.

Smoke Point and Cooking Stability

Some critics argue that olive oil shouldn’t be used for cooking because of its “low smoke point.” However, high-quality extra virgin olive oil has a smoke point of around 375–410°F (190–210°C)—more than adequate for most home cooking, including sautéing and roasting.

More importantly, its high antioxidant content makes it more stable at heat than refined seed oils, which oxidize quickly and form harmful compounds like aldehydes and lipid peroxides when overheated.

Summary: Nutritional Superiority of Olive Oil

To summarize the key nutritional differences:

Olive oil is high in monounsaturated fats, rich in antioxidants, and has anti-inflammatory benefits.
Seed oils are high in omega-6 polyunsaturated fats, lack antioxidants, and are more prone to oxidation and degradation during cooking.

So, if you’re wondering “Is olive oil a seed oil?” from a nutritional standpoint—the answer remains a firm no. Not only is olive oil sourced differently, but it also offers unique health benefits that distinguish it sharply from the inflammatory profile of most refined seed oils.

Is Olive Oil Healthier Than Seed Oils?

When it comes to health, not all fats are created equal. Despite decades of confusion stemming from outdated dietary guidelines that demonized all fats, science has since clarified that the type of fat you consume makes a world of difference. So, how does olive oil compare to seed oils when it comes to health?

In short: olive oil is significantly healthier than most seed oils, especially when consumed in its extra virgin form. This distinction is backed by epidemiological studies, clinical trials, and biochemical research.

Health Benefits of Olive Oil

Extra virgin olive oil (EVOO) is one of the most studied and recommended fats in the world, especially as a central component of the Mediterranean diet, which is consistently linked to longevity and reduced disease risk.

1. Heart Health

The PREDIMED Study, a large-scale clinical trial involving over 7,000 participants in Spain, found that individuals who consumed a Mediterranean diet rich in extra virgin olive oil had:

A 30% lower risk of major cardiovascular events (heart attack, stroke, or death from heart disease)
Improved HDL cholesterol (the “good” cholesterol)
Reduced oxidation of LDL cholesterol, a key factor in atherosclerosis

Study Reference:
Estruch R, Ros E, et al. (2013). Primary prevention of cardiovascular disease with a Mediterranean diet. NEJM.

2. Anti-Inflammatory Effects

Olive oil’s polyphenols—like oleocanthal—are potent anti-inflammatory agents. Oleocanthal acts similarly to nonsteroidal anti-inflammatory drugs (NSAIDs) by inhibiting COX enzymes, which are involved in inflammation pathways.

This helps reduce chronic inflammation, a known contributor to:

Heart disease
Type 2 diabetes
Alzheimer’s disease
Arthritis and autoimmune disorders

3. Cancer Prevention

Preliminary research suggests that compounds in olive oil may help reduce the risk of certain cancers by:

Inhibiting cancer cell proliferation
Promoting apoptosis (natural cell death)
Reducing oxidative DNA damage

Countries with high olive oil consumption, like Greece and Italy, tend to have lower rates of certain cancers, though lifestyle and diet as a whole play a role.

4. Brain and Cognitive Health

Long-term intake of olive oil has been associated with better cognitive function and a reduced risk of neurodegenerative diseases, including Alzheimer’s. This is likely due to:

Anti-inflammatory compounds
Antioxidants protecting brain cells
Improved vascular function

Health Concerns with Seed Oils

Seed oils—such as soybean, canola, corn, and sunflower oil—have grown ubiquitous in modern diets, but not without controversy. While they’re technically “heart-healthy” by some standards (because they lower LDL cholesterol), newer research questions the broader metabolic effects of these oils.

1. Excess Omega-6 Fatty Acids

Seed oils are high in omega-6 polyunsaturated fats, especially linoleic acid, which when consumed in excess may:

Promote systemic inflammation
Worsen insulin resistance
Disrupt healthy omega-6 to omega-3 ratios

A meta-analysis published in Prostaglandins, Leukotrienes and Essential Fatty Acids (2020) noted that modern levels of omega-6 intake may be contributing to chronic inflammation and metabolic disease.

2. Oxidative Stress and Rancidity

PUFAs in seed oils are chemically unstable, especially under heat and light. During refining or cooking, they can form:

Aldehydes (linked to DNA damage)
Lipid peroxides (toxic compounds that harm cells)

Many experts are concerned that the widespread use of seed oils in frying and processed foods increases our exposure to these harmful oxidation products.

3. Industrial Processing Byproducts

Most seed oils are refined, bleached, and deodorized (RBD). This process not only strips beneficial compounds but also introduces trace chemical residues and increases the chance of trans fat formation.

Comparative Overview

Feature	Olive Oil (Extra Virgin)	Seed Oils (e.g., Canola, Soy)
Source	Olive fruit (flesh)	Seeds
Processing	Cold-pressed, unrefined	Chemically refined, high-heat
Main Fat Type	Monounsaturated (Oleic Acid)	Polyunsaturated (Linoleic Acid)
Omega-6 Content	Low	High
Antioxidants & Polyphenols	Rich	Minimal or none
Inflammatory Potential	Anti-inflammatory	Potentially pro-inflammatory
Cooking Stability	High	Low
Backed by Long-Term Studies	Yes (e.g., Mediterranean diet)	Limited and controversial

Conclusion: Olive Oil Wins on Every Front

Olive oil is not only not a seed oil, it is in fact nutritionally superior in nearly every meaningful way. While seed oils are inexpensive and widely used in processed foods, they come with concerns about inflammation, oxidation, and long-term health risks.

In contrast, extra virgin olive oil supports heart, brain, and metabolic health, and is backed by decades of robust research. It is no surprise that nutrition experts and traditional cultures alike have prized it for centuries.

So when asking, “Is olive oil healthier than seed oils?”, the evidence speaks clearly:
Yes. Olive oil is a better, safer, and more nourishing fat.

Common Myths: Is Olive Oil Just Another Processed Oil?

As olive oil gains popularity in the wellness and culinary world, so do misconceptions about its origin, processing, and classification. One of the most persistent myths is that olive oil is “just another processed oil,” no different from industrial seed oils.

This confusion likely arises from the broader category of vegetable oils, under which both olive oil and seed oils technically fall. But make no mistake: olive oil is not a seed oil, and it’s not processed in the same way. Let’s debunk some of the most common myths that fuel this misunderstanding.

Myth #1: “All Oils Are Processed, So Olive Oil Is Too”

It’s true that all oils require some processing to extract the fat from plant material. However, not all processing is created equal.

Extra virgin olive oil is extracted using cold-press mechanical methods—without heat, solvents, or harsh chemicals.
In contrast, most seed oils undergo a multi-stage refining process, including:
- Solvent extraction with hexane
- Deodorization at temperatures up to 500°F (260°C)
- Bleaching with activated clays
- De-gumming and neutralization with caustic soda

Conclusion: Olive oil, particularly in its extra virgin form, is one of the least processed edible oils available, making this myth false.

Myth #2: “Olive Oil Can’t Be Used for Cooking Because It Has a Low Smoke Point”

This is a widely circulated claim, but it’s both misleading and oversimplified.

The smoke point of high-quality extra virgin olive oil is about 375–410°F (190–210°C).
Most home cooking methods—sautéing, baking, roasting—rarely exceed these temperatures.
More importantly, the oxidative stability of olive oil is higher than that of most seed oils, even if they have higher smoke points.

Why? Because EVOO is:

Rich in monounsaturated fats, which are more stable under heat
Loaded with polyphenols and vitamin E, which protect the oil from breaking down

A 2018 study published in the journal ACTA Scientific Nutritional Health tested 10 common cooking oils and found that extra virgin olive oil was the most stable under heat, even more so than avocado oil and coconut oil.

Conclusion: Olive oil is not only safe for cooking—it’s preferable, thanks to its chemical stability and protective compounds.

Myth #3: “Light Olive Oil Is Healthier Because It Has Fewer Calories”

The term “light” olive oil refers to its color and flavor, not its calorie content.

All olive oils—light, virgin, and extra virgin—contain about 120 calories per tablespoon.
“Light” olive oil is more refined, which strips away many of the beneficial polyphenols and antioxidants.
It may be more suitable for high-heat cooking due to its neutral flavor, but it’s not more nutritious than extra virgin varieties.

Conclusion: “Light” olive oil may be useful for certain cooking applications, but it offers fewer health benefits than extra virgin olive oilMyth #4: “Olive Oil Is Just As Bad as Seed Oils If It’s Refined”

There is some truth here: refined olive oils, like most refined oils, undergo processing that removes antioxidants and flavor. However, even refined olive oil:

Is made from the fruit, not seeds
Contains more monounsaturated fats than most seed oils
Is less inflammatory than high-linoleic seed oils like soybean or corn oil

Still, when comparing refined olive oil to extra virgin olive oil, the latter is far superior in nutritional value.

Conclusion: While refined olive oil is not ideal, it is still not a seed oil, and it is nutritionally distinct from highly refined seed oils.

Summary: Olive Oil Is Not “Just Another Processed Oil

When discussing “Is olive oil a seed oil?” and the broader myths surrounding it, it’s clear that olive oil:

Is processed without chemicals or high heat (in its EVOO form)
Retains natural antioxidants and anti-inflammatory compounds
Outperforms seed oils in both nutritional value and cooking stability

Therefore, lumping olive oil into the same category as industrial seed oils is not only scientifically inaccurate, but it also misleads consumers who are trying to make healthier choices.

Choosing the Right Olive Oil: What to Look For

Not all olive oils are created equal. If you want to reap the full health benefits and avoid the downsides of heavily processed oils, it’s critical to choose high-quality extra virgin olive oil (EVOO). But with so many options on store shelves, how do you know you’re getting the real thing?

This section will guide you through how to select the best olive oil — and avoid misleading marketing or diluted products.

1. Look for “Extra Virgin” on the Label

Only extra virgin olive oil (EVOO) is made by cold-pressing olives without chemicals or heat. According to the International Olive Council (IOC), EVOO must meet these standards:

Free acidity level of 0.8% or less
No sensory defects (off flavors, rancidity)
Rich in polyphenols and aromatic compounds

Other types like “pure” or “light” olive oil are refined and lack many of EVOO’s health-promoting compounds.

Reference: International Olive Council – Olive Oil Grades

2. Check for Harvest or Bottling Date

Freshness matters. Olive oil is best consumed within 18–24 months of harvest. A quality product will display the harvest date or best by date—not just an expiration label.

Tip: Choose bottles that list a recent harvest and aim to use the oil within 6 months of opening for maximum flavor and antioxidant potency.

3. Choose Dark Glass Bottles or Tins

Olive oil degrades when exposed to light, heat, and oxygen. High-quality brands will use dark green or brown glass bottles or opaque tins to protect the oil.

Avoid plastic packaging or clear bottles, especially if stored under bright lights, which accelerate oxidation.

4. Look for Origin Information

Authentic olive oils will disclose their country of origin, and often the estate or region where the olives were harvested. Some of the most trusted olive oil-producing countries include:

Italy
Spain
Greece
Portugal
Tunisia

For extra transparency, look for designations like:

PDO (Protected Designation of Origin) in Europe
COOC Seal (California Olive Oil Council) in the U.S.

Reference: California Olive Oil Council Standards

5. Beware of Fraud and Adulteration

Olive oil fraud is a serious issue. A 2010 investigation by the UC Davis Olive Center found that 69% of imported EVOO samples failed sensory standards and were likely adulterated or oxidized.

Some imported “extra virgin” oils are diluted with cheaper seed oils or lower-quality refined oils.

To avoid fraud:

Choose oils with third-party certification (e.g. COOC, NAOOA)
Buy from trusted brands or local producers with clear sourcing
Avoid suspiciously low prices (quality EVOO is rarely cheap)

Reference: UC Davis Olive Oil Study – Adulteration Issues

6. Taste and Smell for Quality

A high-quality EVOO should taste:

Fruity: Notes of green apple, fresh-cut grass, or herbs
Bitter: A sign of healthy polyphenol content
Pungent or peppery: A slight burn at the back of the throat is normal — this is oleocanthal at work

Rancid or old oil will smell like crayons, stale nuts, or wet cardboard — signs the oil has oxidized and lost its health benefits.

7. Buy in Small Quantities

Even the best olive oil won’t last forever. Once opened, olive oil starts to degrade. For this reason:

Buy smaller bottles if you don’t use it often
Store away from heat and sunlight
Always seal tightly to limit oxygen exposure

What This Means for Your Health

While seed oils dominate modern food manufacturing due to their low cost and long shelf life, their refined nature and omega-6 dominance raise significant health concerns — particularly when consumed in excess.

In contrast, extra virgin olive oil offers a range of evidence-based health benefits, including:

Improved cardiovascular health
Reduced inflammation
Enhanced cognitive performance
Support for healthy aging

These benefits are well-documented in numerous clinical trials, most notably the PREDIMED study, which linked daily EVOO intake to a significantly reduced risk of heart disease and stroke (NEJM, 2013).

What You Should Do Next

If you’re trying to clean up your diet, protect your heart, or just make better cooking choices:

Replace industrial seed oils (like soybean, canola, or corn oil) with high-quality extra virgin olive oil.
Use EVOO for sautéing, roasting, salad dressings, and dips.
Look for trusted certifications and fresh harvest dates to ensure quality.
Don’t be misled by the broad term “vegetable oil” — not all plant oils are created equal.

Final Word

So, to reiterate:

Olive oil is not a seed oil. It is a fruit oil derived from the olive fruit, minimally processed, nutrient-rich, and clinically proven to support health and longevity.

When choosing fats for your kitchen, think beyond labels and price tags. Choose oils that work with your body—not against it. Extra virgin olive oil isn’t just not a seed oil; it’s one of the healthiest fats you can consume.

Conclusion

Understanding whether olive oil is a seed oil is essential for making informed dietary choices. Olive oil, unlike seed oils, comes from the fruit of the olive tree and undergoes minimal, gentle processing, preserving its rich antioxidants and heart-healthy monounsaturated fats.

Its unique composition makes it a superior cooking oil and a cornerstone of the Mediterranean diet, renowned for its health benefits. Avoid confusing olive oil with highly processed seed oils, which have a very different nutritional profile and potential health effects.

By choosing extra virgin olive oil from reputable sources, you ensure you’re getting a natural, nutritious oil that supports long-term wellness. So next time you ask, “Is olive oil a seed oil?”, you can confidently say no—and enjoy all the benefits that come with this exceptional fruit oil.
