Is Olive Oil a Seed Oil?

The Clear Answer (And Why It Matters More Than You Think)

If you've spent any time on social media lately, you've probably come across the "seed oil debate." From TikTok videos to wellness podcasts, people are increasingly worried about the oils in their food and one question keeps popping up:

Is olive oil a seed oil?

The short answer is no. But the full story is far more interesting — and understanding it can genuinely change how you think about the oil you use every day.

Let's break it all down.

What Are Seed Oils, Exactly?

Seed oils are cooking oils extracted from the seeds of plants. The most common ones you'll find in American kitchens and processed foods include:

• Soybean oil (the most consumed oil in the US)
• Canola oil (rapeseed oil)
• Corn oil
• Sunflower oil
• Safflower oil
• Cottonseed oil
• Grapeseed oil

What these oils have in common isn't just their source, it's how they're made.

Most seed oils go through a heavy industrial process that involves:

1. Chemical extraction using solvents like hexane (a petroleum-based chemical)
2. High-heat refining to remove the naturally unpleasant taste and odor
3. Bleaching to create a neutral color
4. Deodorizing at extremely high temperatures (over 400°F)

By the time a seed oil reaches your kitchen, it's been stripped of most of its natural nutrients and has undergone significant chemical processing.

This is where olive oil takes a completely different path.

So, Is Olive Oil a Seed Oil?

No. Olive oil is not a seed oil. It is a fruit oil.

This might surprise you, but olives are technically fruits , they're drupes, just like cherries, peaches, and plums. The oil is extracted from the flesh of the olive fruit, not from a seed or kernel.

This distinction isn't just botanical trivia. It fundamentally changes everything about how the oil is produced, what it contains, and what it does inside your body.

Here's What Makes Olive Oil Different:

At Savouidakis, we produce extra virgin olive oil using nothing but mechanical cold pressing, the same fundamental method that has been used in the Mediterranean for millennia. No chemicals, no solvents, no refining. Just olives and pressure.

Why Is the Seed Oil Debate So Big Right Now?

The anti-seed-oil movement has exploded in the US over the past few years, and it's not just a passing trend. Here's what's driving it:

1. The Omega-6 Problem

Seed oils are extremely high in omega-6 fatty acids, particularly linoleic acid. While your body needs some omega-6, the typical American diet now contains up to 20 times more omega-6 than omega-3.

This imbalance has been linked in research to:

• Chronic inflammation
• Heart disease risk factors
• Metabolic issues

Extra virgin olive oil, by contrast, is predominantly monounsaturated fat (oleic acid) — with a much more balanced fatty acid profile.

2. The Processing Concern

Many health-conscious consumers are uncomfortable with the chemical extraction process used for seed oils. The use of hexane, high temperatures, and multiple refining steps feels incompatible with a "clean eating" philosophy.

Cold pressed olive oil requires none of this. The oil is simply squeezed out of the fruit mechanically. The same basic principle humans have used for thousands of years.

3. The Historical Argument

Seed oils are a relatively modern invention. Soybean oil, corn oil, and canola oil only became widely available in the early-to-mid 20th century, often as byproducts of other industries.

Olive oil, on the other hand, has been a dietary staple in Mediterranean cultures for over 4,000 years. In Crete, where our olive oil comes from, olive trees have been cultivated since the Minoan civilization  and Cretans still consume more olive oil per capita than almost anyone on earth.

That's not a marketing claim. That's a 4,000-year clinical trial.

But Wait — Is Olive Oil a "Vegetable Oil"?

This is where things get confusing.

Technically, in the food industry, "vegetable oil" is an umbrella term that can include any oil derived from a plant source — seeds, nuts, or fruits. By this broad definition, olive oil could be categorized as a vegetable oil.

However, when most Americans see "vegetable oil" on a grocery store shelf, it's typically soybean oil or a blend of seed oils. It's a heavily refined, neutral-tasting product that has nothing in common with extra virgin olive oil.

The bottom line:

• Olive oil is NOT a seed oil
• Olive oil is technically a "vegetable oil" in the broadest sense — but it's nothing like what's sold as "vegetable oil" in stores
• Olive oil is a fruit oil, mechanically pressed, unrefined (when extra virgin)

What to Look For When Avoiding Seed Oils

If you're trying to reduce seed oils in your diet, here's what to watch out for and what to look for instead.

Seed Oils to Watch For on Labels:

• Soybean oil
• Canola / rapeseed oil
• Corn oil
• Sunflower oil
• Safflower oil
• Cottonseed oil
• "Vegetable oil" (usually soybean)
• Rice bran oil

Better Alternatives:

• Extra virgin olive oil (the gold standard)
• Avocado oil (also a fruit oil)
• Coconut oil
• Butter / ghee
• Tallow (animal-based)

Among these, extra virgin olive oil stands out because it's the only one backed by thousands of peer-reviewed studies showing health benefits — from heart health to inflammation reduction.

Not All Olive Oil Is Created Equal

Here's the important caveat: when we say olive oil is healthier than seed oils, we're specifically talking about extra virgin olive oil (EVOO).

Discover the Authentic Taste of Extra Virgin Olive Oil at Savouidakis

Lower grades of olive oil — labeled simply "olive oil" or "light olive oil" — are actually refined using some of the same processes as seed oils (heat, filtering, sometimes chemical refining). They lose most of their beneficial compounds in the process.

To get the full health advantage of olive oil over seed oils, look for:

• "Extra Virgin" on the label
• A harvest date (not just an expiration date)
• High polyphenol content, the antioxidants that make EVOO special
• Single origin, you know exactly where it comes from
• A named producer or estate (not a faceless brand)
• Recognized quality, look for international awards and competition results as proof of excellence (Discover Savouidakis' olive oil certifications)
• Independent certifications that verify production standards and authenticity (Learn about Savouidakis' olive oil awards)
• Dark bottle or tin (protects from light degradation)

The Fatty Acid Comparison: Olive Oil vs Seed Oils

Here's what the fat profile actually looks like:

Notice how olive oil and avocado oil are dominated by monounsaturated fats, while most seed oils are loaded with polyunsaturated omega-6 fats.

This fatty acid profile is one of the key reasons the Mediterranean diet, which uses olive oil as its primary fat source, is consistently ranked the #1 diet in the world by U.S. News & World Report.

The Koroneiki olive variety, which we grow in the Messara Valley of southern Crete, is known for producing EVOO with exceptionally high oleic acid content, often above 75%. This, combined with its naturally high polyphenol levels, is what gives Cretan Koroneiki oil its distinctive peppery finish and superior nutritional profile.

So, Should You Replace Your Seed Oils with Olive Oil?

Based on the evidence, yes! Replacing seed oils with extra virgin olive oil is one of the simplest upgrades you can make to your diet.

And despite what you may have heard, EVOO is perfectly fine for cooking. Its smoke point is around 374–405°F (190–207°C), which is more than adequate for sautéing, roasting, and even frying. Studies have actually shown that EVOO is more stable at high heat than many seed oils, thanks to its antioxidant content.

You can use extra virgin olive oil for:

• Sautéing and pan-frying
• Roasting vegetables
• Salad dressings and marinades
• Baking (yes, really — it replaces vegetable oil 1:1)
• Drizzling over finished dishes
• Dipping bread

Frequently Asked Questions

Is olive oil inflammatory like seed oils?

No. Unlike seed oils, which are high in omega-6 and may promote inflammation when consumed in excess, extra virgin olive oil contains oleocanthal — a natural compound with anti-inflammatory properties so powerful that researchers have compared it to ibuprofen. Studies published in Nature have confirmed this effect.

Is olive oil healthier than seed oils?

Yes, according to the vast majority of nutritional research. Extra virgin olive oil retains its natural antioxidants, polyphenols, and vitamins because it's not chemically refined. It's the primary fat in the Mediterranean diet, which is associated with lower rates of heart disease, diabetes, and certain cancers.

Can I cook with olive oil instead of seed oil?

Absolutely. Extra virgin olive oil has a smoke point of approximately 374–405°F and has been shown to be highly stable during cooking. You can substitute it 1:1 for any seed oil or vegetable oil in your recipes.

Is canola oil a seed oil?

Yes. Canola oil is extracted from the seeds of the rapeseed plant and undergoes chemical refining, bleaching, and deodorizing — the typical seed oil production process.

Is avocado oil a seed oil?

No. Like olive oil, avocado oil is a fruit oil — it's pressed from the flesh of the avocado. However, a 2023 UC Davis study found that 82% of avocado oils tested were either rancid or mixed with other oils, so quality control is a serious concern.

What's the healthiest oil to replace seed oils with?

Most nutritionists and researchers point to extra virgin olive oil as the top recommendation. It's the most studied culinary oil in the world, with consistent evidence of health benefits across thousands of studies. For maximum benefit, choose certified, award-winning EVOO from a single estate with traceable origins.

The Bottom Line

Olive oil is not a seed oil. It's a fruit oil, cold pressed from olives without chemicals, solvents, or industrial refining.

In a world where seed oils are hiding in almost every processed food on grocery store shelves, choosing authentic extra virgin olive oil is one of the most impactful decisions you can make for your health.

But not all EVOO is equal. Look for single-origin, cold pressed, high-polyphenol extra virgin olive oil from trusted, certified producers — ideally from regions with centuries of olive oil heritage, like Crete.

Because the best oil isn't made in a factory. It's made in a grove.
