The health question is not which oil, but which bottle \u2014 and how recently it was pressed.<\/figcaption><\/figure>\n

Ask which olive oil is healthiest and you will usually be handed a brand name. That is the wrong shape of answer. Every extra virgin olive oil in the world carries about 120 calories a tablespoon and a fat profile dominated by oleic acid. On the nutrition panel, the cheapest bottle in the supermarket and the finest single-estate oil in Italy are practically indistinguishable.<\/p>\n

The difference is in the part the label does not measure. And it is not a small difference.<\/p>\n

The compounds the research is actually about<\/h2>\n

When scientists study the health effects of olive oil, they are rarely studying fat. They are studying phenolic compounds<\/strong> \u2014 hydroxytyrosol, tyrosol, oleocanthal, oleuropein and their relatives. These are water-soluble antioxidants carried out of the fruit along with the oil, and they are the reason a good oil tastes green, bitter and peppery rather than merely rich.<\/p>\n

The European Commission thought the evidence strong enough to authorise a specific health claim: olive oil polyphenols contribute to the protection of blood lipids from oxidative stress, provided the oil contains at least 5 mg of hydroxytyrosol and its derivatives per 20 g of oil. That threshold matters more than any marketing word on the front of the bottle, because a great many oils sold as extra virgin do not come close to meeting it.<\/p>\n

Oleocanthal \u2014 the compound responsible for the peppery catch at the back of your throat \u2014 was identified as an anti-inflammatory acting on the same enzymes as ibuprofen, in laboratory conditions. That is a mechanism, not a prescription; nobody should treat a spoonful of oil as medicine. But it does tell you something useful: the sensation is the signal<\/em>. A bottle that makes you cough has the compounds. A bottle that tastes like nothing has already lost them.<\/p>\n

What actually destroys them<\/h2>\n

Polyphenols are fragile and finite. Nothing downstream can add them back. They are lost to four things, in this order of severity:<\/p>\n
