Scientists Unravel Secret behind Health Benefits of Mediterranean-Style Diet

Scientists have found that eating food cooked or soaked in olive oil represses several genes which trigger inflammation in the body.

Francisco Perez-Jimenez, from the University of Cordoba, in Spain, who led the study, said: “These findings strengthen the relationship between inflammation … and diet and provide evidence at the most basic level of healthy effects derived from virgin olive oil consumption in humans.”

And added” Several of the repressed genes are known to be involved in pro-inflammatory processes, suggesting that the diet can switch the activity of immune system cells to a less (harmful) profile.”

Inflammation can trigger conditions such as atherosclerosis, or furring of the arteries. As well as reducing heart problems, studies have also suggested that adhering to a Mediterranean-style diet can reduce the risk of developing Type 2 diabetes, Alzheimer’s disease and even depression.

June Davison, cardiac nurse at the British Heart Foundation, said: “This research suggests an interesting reason why olive oil may be helpful in protecting the heart.

“This study found that phenols – a micronutrient of olive oil – ‘dampened down’ genes that can cause inflammation. That’s important as inflammation is linked to the development of cardiovascular disease.

“It supports current advice that it’s better to use unsaturated fats such as olive and rapeseed oil, over saturated fats such as butter, lard and ghee. However any oil you use should still be used sparingly as it is high in calories.”
