Olive oil, this staple of the Mediterranean diet is on the rise. Olive oil is a popular topping for salads, but today some opt for a more generous and direct drizzle in a glass. In fact, they use it for its purported health benefits by drinking it neat. But despite the buzz, the origins of olive oil consumption are hard to trace. Some testimonies suggest that it is an ancestral practice in the Mediterranean regions. It is said that a glass of olive oil served as breakfast for the Greeks of the island of Crete, who had a long life. Are the benefits worth it (literally) or is this a passing fad?

What are the potential health benefits of consuming olive oil?

Olive oil is a powerful ingredient: It has anti-inflammatory and antioxidant properties, according to an article published in Cells in 2020. But scientific data does not suggest that you should drink olive oil like a shooter. There is no solid research to suggest that any of the potential benefits could not be achieved by incorporating olive oil into recipes, rather than drinking it directly.

Hundreds of studies have looked at the potential benefits of olive oil used in food preparation. Yet few of them have studied the effects of consuming this “liquid gold”, the nickname that the Greek poet Homer would have given to this pantry staple.

One caveat: while olive oil has benefits for gut health, claims that it can help reduce bloating are anecdotal. It might work for some people, but not for everyone. That’s because we don’t all have the same eating habits, or the same factors that also influence digestion, such as stress, hormonal fluctuations, medications, food intolerances, and physical activity habits.

What are the potential side effects of consuming olive oil?

Drinking small amounts of olive oil should not cause harm or elicit negative side effects for most people.
