Olive oil is commonly used in foods. As medicine, people most commonly use olive oil for heart disease, diabetes, and high blood pressure. It is also used for high cholesterol, cancer, memory and thinking skills, migraine, obesity, and many other conditions, but there is no good scientific evidence to support many of these other uses.

Don't confuse olive oil with olive. These are not the same.

Uses & Effectiveness ?

Possibly Effective for

Breast cancer. Consuming more olive oil in the diet seems to be linked with a lower risk of developing breast cancer.

Heart disease. People who cook using olive oil seem to have a lower risk of heart disease and lower risk of first heart attack compared to those who cook with other oils. But it's unclear if higher dietary intake of olive oil helps people who already have heart disease.
