Olive oil has a fascinating past; healthy, delicious present

For thousands of years olive oil was food, medicine, fuel, cosmetic and sacred anointing all at once. Much of that is myth — but the modern, evidence-based picture is quietly impressive in its own right. Here is the long story, de-hyped.

The origin of olive oil is genuinely lost to us — cultivated olives go back more than six thousand years around the eastern Mediterranean — but its hold on human imagination is easy to trace. Homer called it liquid gold. Greek athletes rubbed it on their bodies before competing and wore crowns of olive branches when they won. Kings and priests were anointed with it, it burned in lamps, it went into medicine and cosmetics, and the olive branch became the universal sign of peace. For the peoples of the Mediterranean it was never just a cooking fat; it was wealth, ritual and status pressed into a bottle. The trick, reading all this today, is to enjoy the romance without letting it stand in for evidence.

A past soaked in myth

Almost every ancient culture that grew the olive wrapped it in story. In Greece the tree was said to be Athena’s own gift to the city that took her name. The oil was believed to carry strength and restore youth, which is why it found its way into everything from athletic training to funerary rites. Some of this reflects real, practical value — a stable, energy-dense oil that keeps well was genuinely precious in the ancient world — and some is pure legend. Both are worth knowing, as long as you keep them apart. The history tells you why olive oil matters culturally; it does not, on its own, tell you anything about your cholesterol.

The healthy present, de-hyped

Here is the sober modern picture. Olive oil, and especially extra virgin, is rich in monounsaturated fat (chiefly oleic acid), which is associated with better blood-lipid profiles when it replaces saturated fats like butter. Extra virgin also carries polyphenols — natural antioxidant compounds, most concentrated in fresh, robust, peppery oils — and vitamin E. It is a well-studied cornerstone of the Mediterranean dietary pattern, which as a whole way of eating has good evidence behind it. What that does not mean is that oil is a medicine or a cure. It is a healthful fat, not a health supplement, and it is still calorie-dense — a useful thing to remember before you drown the salad. This is general information, not medical advice.

The best way in: taste it properly

The most enjoyable way to understand olive oil is not to read about it but to taste several side by side. It costs almost nothing to run a little tasting at home : gather a few different oils, pour a small amount of each into separate cups (opaque or plain, so colour doesn’t bias you), and warm the cup in your hand. Smell first — hunt for grass, tomato leaf, apple, almond — then sip and let the oil coat your tongue, noticing the bitterness and the peppery catch at the back of the throat that mark a fresh, lively oil. Have plain bread and water to reset between them. Do it with friends and compare notes; you will learn more about what you actually like in twenty minutes than in any amount of label-reading.

Sensible takeaways

• Enjoy the history as culture, not as a health claim — the two are separate things.
• Choose extra virgin for the most monounsaturated fat, polyphenols and vitamin E.
• Use it to replace butter and other saturated fats, rather than simply adding more oil.
• Remember it is calorie-dense — healthful does not mean unlimited.
• Run a home tasting to learn what you like; fresh, peppery oils are the liveliest.

Olive oil, past and present: common questions

Why did Homer call olive oil ‘liquid gold’?

Because in the ancient Mediterranean it was genuinely valuable — food, fuel, medicine, cosmetic and sacred anointing in one — a stable, energy-dense oil that also carried real ritual and status.

Is olive oil actually healthy, or is that hype?

It is a healthful fat, backed by reasonable evidence. It is high in monounsaturated fat and, as extra virgin, in polyphenols and vitamin E, and is central to the well-studied Mediterranean diet — but it is a food, not a medicine.

Which olive oil is best for health?

Fresh extra virgin. It is unrefined, so it keeps the most polyphenols and vitamin E, especially in robust, peppery styles pressed from a recent harvest.

Can I use as much as I like because it’s healthy?

No. Olive oil is calorie-dense like any oil — around 120 calories a tablespoon — so it is best used to replace less healthy fats rather than simply added on top.

How can I learn to appreciate olive oil?

Taste a few side by side at home : smell for grassy, fruity aromas, sip to feel the bitterness and peppery finish of a fresh oil, and compare with friends.
