How Much Extra Virgin Olive Oil Should You Eat Per Day?

When I lived in Spain, nobody measured their extra virgin olive oil. There was no tablespoon in sight, ever. The bottle just sat on the table the way salt does.

So when people ask me how much extra virgin olive oil they should eat per day, I always point back to PREDIMED. But I also like to mention this: the average American gets less than a teaspoon of olive oil a day — and most of that isn't even extra virgin. In Spain, people go through fifteen times more of it a year.

What the research actually says

Major Mediterranean diet studies, including the widely cited PREDIMED trial, generally point to about 3 to 4 tablespoons of extra virgin olive oil per day. That range — roughly 45 to 60 milliliters, or about a quarter cup — is associated with the benefits people often want: better heart health markers, steadier blood sugar, and lower inflammation.

I know what you're thinking. That's a lot. But nobody's drinking a shot of it. It adds up over a normal day of cooking without you noticing — a couple tablespoons to sauté vegetables, a drizzle to finish a dish, a generous pour into a vinaigrette, extra virgin olive oil instead of butter on your toast. By dinner, you're closer to that number than you'd guess.

Why the amount matters less than the habit

Here's the thing though. Those studies weren't testing extra virgin olive oil like a supplement. I bring this up because a scientist at FISABIO actually laughed — out loud — when I told her people in the US take it as shots. She and her colleagues were just watching how people already ate, a pattern that had existed for generations before anyone thought to measure it. Extra virgin olive oil wasn't the intervention. It was just... there. The constant underneath everything else.

And that's the part that gets lost when you reduce this to tablespoons. Extra virgin olive oil earns its place by being the default fat you reach for, used often and without thinking about it — not sprinkled on top of a diet that otherwise stayed the same.

What this actually looks like day to day

Honestly, most of it isn't complicated. I add a real pour to soup, to make roasted vegetables or scrambled eggs. It makes the food taste better. Always keeping the bottle somewhere I'll actually reach for it.

Does the quality of the oil actually matter?

It does, and here's why. Extra virgin olive oil is a fresh fruit juice. The polyphenols start fading the moment it's pressed, so a real harvest date tells you more than anything printed on the front label. Same with acidity — the lower it is, generally, the faster and more carefully the oil was made. And it also makes it more stable and better for cooking.

Which brings it back to the same point from earlier: the amount only matters if the oil is one you trust enough to pour generously. Nobody measures the good stuff.
