Olive oil and cancer Back


A study published in The Journal of the National Cancer Institute revealed that consuming several servings of olive oil a day together with lots of vegetables and fruits appears to lower the risk of developing breast cancer. Olive oil’s potential ability to fight against breast cancer is via the oleic acid, the main monounsaturated fatty acid in olive oil, shown in one study to suppress Her-2/neu, a cancer gene which is responsible for 25% to 30% of all breast cancer. Olive oil is also found to improve the efficiency of Trastuzumab (Herceptin®), a drug which is used to treat many breast cancer patients.

Colon Cancer

Oleic acid together with antioxidants, flavonoids, squalene and phenols present in olive oil may protect against colon cancer. Deoxycyclic acid, a type of bile acid, is highly connected to the development of colon cancer.  It reduces the amount of enzyme diamine oxidase (DAO) in the body which regulates the normal cell division in the bowel, thus increasing the risk of abnormal cancerous cells development. Olive oil may protect against colon cancer by reducing the amount of deoxycyclic acid and regulating the level of DAO in the body.

Olive Oil and Prostate Cancer

Prostate cancer is more common among males. Studies have shown that there may be a correlation between the risk of prostate cancer and high saturated fat diet (particularly red meat). Olive oil which is naturally rich in plant sterols and oleic acid (a monounsaturated fat) is being thought as capable of inhibiting the growth of prostate cancer tumour and reducing the release of prostate-specific antigen.
