A compound found in olive oil may help to prevent cancer developing in the brain, a study shows. Research into oleic acid – the primary ingredient in olive oil – has shown how it can help prevent cancer-causing genes from functioning in cells. The oily substance – a fatty acids – stimulates the production of a cell molecule whose function is to prevent cancer-causing proteins from forming.

The study team says it is too soon to say whether dietary consumption of olive oil may help prevent brain cancer. Their findings, however, point towards possible therapies based on the oil to prevent brain cancer from occurring...

Might it be possible to ‘turn off’ a food allergy? Credit: © bit24 / Fotolia

A team led by A/Prof Ray Steptoe at UQ Diamantina Institute has been able to ‘turn-off’ the immune response which causes allergic reaction in animals. “When someone has an allergy or asthma flare-up, the symptoms they experience results from immune cells reacting to protein in the allergen,” Professor Steptoe said. “The challenge in asthma and allergies is that these immune cells, known as T-cells, develop a form of immune ‘memory’ and become very resistant to treatments.

“We have now been able ‘wipe’ the memory of these T-cells in animals with gene therapy, de-sensitising the immune system so that it tolerates the protein...
