Key mechanism links virgin olive oil to protection against breast cancer - Science Daily, 6/30/10 - "virgin olive oil is associated with higher incidences of benign breast tumours and at the same time with a decrease in the activity of the p21Ras oncogene, which spurs uncontrolled cell proliferation and stimulates the growth of tumours. In addition, olive oil suppresses the activity of some proteins, such as the AKT, essential for the survival of cells since they prevent apoptosis, the cell's "suicide" programme. Between proliferation and apoptosis in tumour cells, these effects tip the balance towards cell death, thereby slowing the growth of tumours" - See olive leaf extract at Amazon.com.
Virgin olive oil and a Mediterranean diet fight heart disease by changing how our genes function - Science Daily, 6/30/10 - "The first group consumed a traditional Mediterranean diet with virgin olive oil rich in polyphenols.

After three months, the first group had a down-regulation in the expression of atherosclerosis-related genes in their peripheral blood mononuclear cells. Additionally, the olive oil polyphenols made a significant impact on the expression of genetic changes influencing coronary heart disease. Results also showed that the consumption of virgin olive oil in conjunction with a Mediterranean diet can positively impact lipid and DNA oxidation, insulin resistance, inflammation, carcinogenesis, and tumor suppression ... olive oil and a Mediterranean diet affect our bodies in a far more significant way than previously believed" - See olive leaf extract at Amazon.com.
