Scientists Give Answers to Olive Oil's 'Cancer Curing' Properties
03 Mar 2015 --- Extra virgin olive oil (EVOO), long-known for its heart health benefits, is now attracting attention for its ability to swiftly destroy cancer cells, according to a recent study.
Scientists have already shown that the oleocanthal compound in EV00 causes death in cancer cells, but - after an in-depth study into the matter - they are now able to give an explanation for this.
In the paper 'Oleocanthal Rapidly and Selectively Induces Cancer Cell Death Via Lysosomal Membrance Permeabilization (LMP)', published in Molecular & Cellular Oncology, scientists offer some answers to this.
In their recent study, the researchers discovered that the key to understanding the toxic effect of oleocantha in cancerous cells lies in its reaction with the lysosomes of the cell, where the cells store waste: the oleocantha ruptures the cancer cell lysosomes causing cell death within 30 minutes to an hour while leaving un-cancerous cells unharmed.
This suggests that the lysosomal membranes of cancerous cells are weaker than those of uncancerous cells. Because of oleocantha’s targeted damage to cancer cells, it may prove an ideal option for therapeutic cancer treatment.
Paul Breslin, co-author of the study, said “The mechanism of killing cancer cells and sparing healthy cells, lysosomal membrane permeabilization, has been hypothesized as a possible mechanism of effectively killing cancer cells and sparing healthy tissues but has never been realized before. Our realization of this makes this paper of particular therapeutic interest for cancer treatment.”
The study’s focus on the effect of oleocantha on cancerous and un-cancerous cells leads to larger implications about the health benefits of the Mediterranean diet, which is rich in EVOO.
Breslin stated, “the Mediterranean diet is known to be associated with a reduced risk of many different kinds of cancer. Whereas the entire diet likely has many benefits, this study points directly to the olive oil phenolic, oleocanthal, as playing an especially important role in these observations.
As more people turn to the Mediterranean diet as a healthy life option, oleocanthal is growing in its significance as a key active component of this diet.”
