Olive Polyphenols may inhibit colon cancer

Nov 14, 2005

Research indicates that olive ingredients may inhibit colon cancer. In this study, researchers from the University of Ulster, N. Ireland, studied these anticancer effects by adding olive polyphenols to cell lines normally used to study colorectal cancer. They found that olive polyphenols inhibit the process where colon cells become cancerous.

Adding olive polyphenols to the cell lines for 24 hours prevented the cells from mutating (an early step in the cancer process)

Adding the olive polyphenols for 48 hours actually inhibited the promotion of cancer and decreased the invasiveness of colon cancer cells.

The greater the concentration of olive polyphenols the stronger the protection from colon cancer. The study is published in the October 20th, 2005 issue of the International Journal of Cancer.

Hopefully none of us will encounter an agent as destructive as mustard gas, but it is good for us to note that these particular antioxidants are very lung friendly and that available oral supplement levels have shown protective activity in research.

Olive Polyphenols help protect blood vessel walls and help decrease the risk of developing hardening of the arteries

In this study an olive oil that was very high in olive polyphenols was given to healthy adults along with bread. They also had a meal with olive oil stripped of polyphenols along with bread. After consuming the olive polyphenols, the inner lining of the small blood vessels in the fingers improved in function and the concentration of heart healthy blood components such as nitric oxide also increased, Nitric oxide improves blood flow and helps normalize blood pressure. There was no such improvement with the olive oil devoid of the polyphenols. This study shows that the olive polyphenols may have significant effects in reducing the risk of atherosclerosis (hardening of the arteries) and these polyphenols are an important component in the heart-healthy Mediterranean diet. The study is published in the November 15th, 2005 issue of the Journal of the American College of Cardiology.
