What are polyphenols and why do they matter?

Polyphenols are the antioxidant compounds in real olive oil responsible for its bitterness and pepper. They help protect blood lipids from oxidative stress, an effect authorised by the European Food Safety Authority, and are a major reason the Mediterranean diet supports heart and brain health.

How much polyphenol does WOW Longevity olive oil contain?

WOW Longevity delivers 190 mg of polyphenols per 15 ml serving, far above typical supermarket olive oils, which are often largely stripped of them.

How do you take high-polyphenol olive oil?

One 15 ml spoonful a day, taken neat or poured raw over food just before serving. Avoid cooking with it, as heat destroys the polyphenols.

What the longest-lived people actually eat

The blue zones share a pattern rather than a superfood: mostly plants, very little ultra-processed food, moderate portions, daily movement and strong social ties. In the Mediterranean zones, real olive oil runs through nearly every meal, used generously and raw.

Key points

There is no single miracle food. There is a repeatable pattern.
In Ikaria and Sardinia, olive oil appears in almost every meal, and it is used raw.
PREDIMED found roughly 30 percent fewer cardiovascular events on a Mediterranean diet rich in extra virgin olive oil.
The oil that built those diets was fresh, unrefined and full of polyphenols. Most modern oil is not.

The blue zones are the handful of places where people reach very old age in unusual numbers and stay healthy while they do it: Ikaria in Greece, Sardinia in Italy, the Nicoya Peninsula in Costa Rica, and others. Researchers have spent decades looking for what they share.

A pattern, not a superfood

There is no single miracle food. What shows up instead is a pattern: mostly plants, beans and whole grains, very little ultra-processed food, moderate portions, movement built into daily life, and strong social ties. In the Mediterranean zones, one ingredient runs through nearly every meal: olive oil, used generously and raw.

What the trials found

This is not just folklore. The PREDIMED trial, the largest dietary study of its kind, randomised thousands of high-risk adults to a Mediterranean diet rich in extra virgin olive oil, and saw roughly a third fewer major cardiovascular events than a low-fat control. Large Harvard cohorts have since linked higher olive-oil intake with lower overall mortality across several separate causes. The through-line is real olive oil, eaten consistently.

The part we forgot

The oil that built those diets was fresh, local, unrefined and full of polyphenols. Somewhere along the way, most of us traded it for something refined, deodorised and months old, and wondered why it did not feel the same. Bringing back the real thing, as a simple daily habit, is the entire idea behind WOW Longevity.

Common questions

What do people in the blue zones eat?

Mostly plants, beans and whole grains, with very little ultra-processed food and moderate portions. In the Mediterranean blue zones, olive oil is used generously and raw in nearly every meal.

Does olive oil help you live longer?

Large Harvard cohort studies associate higher olive-oil intake with lower overall mortality, and the PREDIMED randomised trial found roughly 30 percent fewer major cardiovascular events on a Mediterranean diet rich in extra virgin olive oil.

Which olive oil do blue zone populations use?

Fresh, local, unrefined oil, high in polyphenols. It is quite different from the refined, deodorised oil that dominates most supermarket shelves today.
