Let’s Talk Olive Oil: How to Actually Buy a Good One

Wendy Francis, NBC-HWC – Board-Certified Health Coach and Functional Nutritionist

Olive oil is one of those “healthy staples” almost everyone has in their kitchen… but here’s the truth:

Not all olive oil is created equal. Not even close.

As a health coach, this is one of the biggest “back to basics” upgrades I recommend. Because when you choose a high-quality olive oil, you're not just cooking — you're supporting your brain, heart, inflammation levels, and overall health.

But when you buy blindly or go for the cheapest bottle on the shelf… you could be getting something very different than what you think.

Why Olive Oil Quality Actually Matters

Real, high-quality extra virgin olive oil is rich in antioxidants and healthy fats, especially polyphenols — the compounds that help reduce inflammation and support brain and heart health.

Lower-quality oils? They often lose these benefits due to poor processing, long storage times, or even dilution with other oils.

So instead of nourishing your body… you're just adding calories with very little benefit.

What Can Go Wrong with Cheap Olive Oil

This is where people are often surprised.

• It may be old or oxidized
• It may be blended with lower-quality oils
• It may not actually be “extra virgin” despite the label
• It may have been exposed to heat and light, degrading its nutrients

And here’s the kicker — olive oil is one of the most commonly adulterated food products in the world.

Meaning what’s on the label isn’t always what’s in the bottle.

How to Shop for a High-Quality Olive Oil

Here’s what I personally look for and what I recommend to clients:

1. Look for “Extra Virgin” — But Don’t Stop There

This is the least processed form, but it’s not enough on its own. You want confirmation of quality beyond just the front label.

2. Check for a Harvest Date

This is huge.

Olive oil is best within 12–18 months of harvest. If there’s no date, that’s a red flag.

3. Choose Dark Glass Bottles

Light damages olive oil. Clear bottles may look pretty… but they’re not protecting what’s inside.

4. Look for Single-Origin or Specific Regions

Instead of vague labels like “Product of multiple countries,” look for oils sourced from one region or farm.

5. Certifications Help

Seals like PDO (Protected Designation of Origin) or third-party testing certifications can add another layer of trust.

6. Trust Your Taste

Good olive oil should taste fresh, slightly peppery, and a little bitter — that’s a sign of those beneficial polyphenols.

What to Avoid

• Plastic containers
• Very cheap pricing (if it seems too good to be true… it probably is)
• No harvest date
• Labels that are vague or overly generic

The Bottom Line

This is one of those small changes that can make a big difference.

You don’t need to buy the most expensive bottle on the shelf… but you do want to be intentional.

Because when you upgrade something you use every single day, you’re consistently giving your body better inputs.

And that’s where real change happens.
