Extra-Virgin Olive Oil — Four Spoons of Evidence
Around four tablespoons a day of true extra-virgin olive oil was associated with markedly fewer major cardiovascular events in PREDIMED (about 30% in the trial's own reporting), the largest Mediterranean-diet trial ever run — and the peppery catch in the throat is the polyphenol you are tasting.
How it works
Two families do the work: the oleic acid that makes up most of the oil, and a small, wildly variable dose of polyphenols — hydroxytyrosol and oleuropein (which carry an authorized European claim for protecting blood lipids from oxidative stress) and oleocanthal, which acts on the same enzyme pathway as common anti-inflammatory medicines. Polyphenol content ranges a hundred-fold between bottles: early-harvest green olives, fast milling, dark glass, and freshness (harvest date under 18 months) keep it; heat, light, age, and 'light' or blended oils lose it.
The practice
Two to four tablespoons a day, raw or at gentle heat: over greens and grains, into legumes, a spoon with bread instead of butter. Buy by harvest date, in dark glass or tin, from a single origin, and trust bitterness and pepper — blandness means the medicine has gone.
The tradition
The Mediterranean kitchen's oil-as-medicine; Ayurveda's sneha — the doctrine that the right fat, in the right amount, is nourishment rather than indulgence
Cautions
- ⚠ It is still 120 calories a spoon — it replaces other fats.
- ⚠ Fraud is common in cheap 'extra-virgin' — the harvest date and taste are your only protection short of a lab.
