A new study has shown that a main ingredient in olive oil can help stop certain cancer-inducing genes from functioning inside a cell. The scientists say it is still too early to know whether or not ingesting olive oil can prevent brain cancer.

The Research

A new study about the effects of oleic acid- the main ingredient in olive oil- has shown that it could help stop certain cancer-inducing genes from functioning inside a cell.

The experts explained that oleic acid stops a cell protein called MSI2 from inhibiting the production of a molecule called miR-7, which halts the activity of certain oncogenes inside a cell- ultimately preventing tumour formation and development.

The researchers used human cell extracts and live cells to perform their experiments.

The miR-7 molecule is particularly active in the brain. However, the researchers said that it is still too early to tell whether or not ingesting olive oil can prevent brain cancer.

Comments on the Research

Gracjan Michlewski, the scientist who led the study, said: “While we cannot yet say that olive oil in the diet helps prevent brain cancer, our findings do suggest that oleic acid can support the production of tumour-suppressing molecules in cells grown in the lab.

“Further studies could help determine the role that olive oil might have in brain health.”

Despite this, the researchers said that their discovery does point towards the potential of using oil therapies to prevent brain tumour formation.

Previous Research

Previous research has also shown a correlation between a Mediterranean diet supplemented with extra virgin olive and lower breast cancer risk. However, no research has proven a causal link between them as of yet. It is important not to jump to conclusions regarding possible cancer treatments until it has been fully corroborated by scientific research.
