Olive Oil vs. Seed Oils: What’s Really in Your Bottle?

05/06/2026 | Ghiggeri’s Of Honesdale | About Olive Oil

If you’ve spent any time scrolling through wellness videos lately, you’ve probably heard the words “seed oils” tossed around like a dirty secret. Meanwhile, olive oil is having a moment again. So what’s actually going on inside those bottles in your pantry, and why does it matter for how you feel after dinner?

Let’s pour a little clarity into the conversation.

How they’re made (this is the big one)

Real extra virgin olive oil is essentially freshly pressed fruit juice. Olives go in, oil comes out, usually within hours of harvest, using nothing more than a press and a centrifuge. No heat, no chemicals, no shortcuts. That’s why a good bottle smells like a sunny grove and tastes peppery and alive.

Seed oils (think canola, soybean, corn, cottonseed, sunflower, safflower, and “vegetable oil” blends) take a very different path. The world’s top commodity oilseeds are typically cleaned, cracked, cooked, flaked, and then bathed in hexane, a solvent derived from petroleum, to pull the oil out of the seed. What’s left is then refined, bleached, and deodorized. The industry literally calls these “RBD oils.” The end product is shelf stable and cheap, but a long way from anything you’d call fresh.

What that means for your body

Olive oil is rich in monounsaturated fats and naturally occurring polyphenols, the antioxidants behind so much of the Mediterranean diet research. The European Food Safety Authority has gone so far as to authorize an official health claim that olive oil polyphenols help protect blood lipids from oxidative stress, provided the oil contains at least 5 mg of hydroxytyrosol and its derivatives per 20 g. One of those polyphenols, oleocanthal, even acts on the same COX enzymes that ibuprofen does. It’s the compound responsible for that gentle peppery sting in the back of your throat when you taste a fresh, premium oil.

The PREDIMED trial, one of the largest dietary studies ever run, randomized nearly 7,500 adults at high cardiovascular risk to either a Mediterranean diet supplemented with extra virgin olive oil, the same diet with mixed nuts, or a low fat control. After about five years, the olive oil and nut groups saw roughly a 30% relative reduction in major cardiovascular events compared to the low fat group.

Seed oils, on the other hand, are heavy in omega 6 fatty acids. Omega 6s aren’t villains on their own (your body actually needs some), but the modern Western diet delivers them in huge amounts. Researchers estimate the typical omega 6 to omega 3 ratio has climbed to roughly 15:1 or even higher, compared to the roughly 1:1 ratio humans evolved on, and a growing body of work links that imbalance to chronic, low grade inflammation and a higher risk of cardiovascular and autoimmune disease.

What about cooking?

Here’s a myth worth busting: good extra virgin olive oil is absolutely fine for everyday cooking. Its smoke point sits in the 350 to 405°F range, plenty for sautéing, roasting, and most pan work. More importantly, smoke point alone isn’t the right yardstick. In direct cooking comparisons, extra virgin olive oil actually outperformed oils with higher smoke points in oxidative stability, producing fewer polar compounds and trans fats during heating, thanks to its antioxidants and monounsaturated fat profile.Save your most delicate, peppery bottles for finishing. Drizzle them on soup, eggs, roasted vegetables, or a hunk of crusty bread, and use a sturdier everyday EVOO for the stove.

The simplest swap you can make

If you only change one thing in your kitchen this month, swap your “vegetable oil” for a real extra virgin olive oil. Your salad dressings will taste better, your roasted potatoes will get crispier edges, and you’ll be cooking with something your grandmother would have actually recognized as food.

Come taste the difference

The honest truth is that olive oil is one of those things you really have to taste to understand. A grassy Tuscan, a buttery Spanish Arbequina, and a bold Greek Koroneiki are three completely different experiences, and none of them taste anything like the bland stuff in the supermarket plastic jug.
