Olive oil benefits in our health

An international team of scientists led by researchers from the University of Granada has made a major breakthrough, having found that certain dietary habits can have an extremely damaging effect on the liver.

As reported in their study in the journal Journal of Nutritional Biochemistry, liver damage results in a form of non-alcoholic disease called steatohepatitis (NASH).

Non-alcoholic steatohepatitis is characterized by inflammation in the liver. This is a very serious condition that is a risk factor for more serious harm, such as cirrhosis and liver cancer. It is more common in older people and is estimated to affect 1-3% of children, 5% of adolescents, 18% of adults 20-40 years of age, 39% of adults 40-50 years and over 40% of adults 70 years of age and above.

The purpose of the study was to look at the long-term effect of various fats on the liver, including those derived from olive oil, sunflower oil and fish. In this context, the researchers conducted a series of tests on experimental animals (mice), monitoring their liver health in the long run.

As José Luis Quiles Morales, a professor of physiology at the University of Granada and one of the researchers who conducted the trials, "our research has shown that fat accumulates in the liver over time, but our most important finding was that the type of fat that accumulates depends on the fat that is taken through the diet ". This, in addition, means that the liver grows at a different rate depending on diet and is therefore more or less prone to disease.


Of the three types of fats studied - extra virgin olive oil, sunflower oil and fish oil - extra virgin olive oil was what seemed to contribute to the greatest extent to good liver health throughout life.

Sunflower oil has been associated with the subsequent onset of fibrosis, with changes in liver structure, with "blocking" the expression of certain genes but also with high levels of oxidation in the liver.

As for fish oil, the experiments indicated that they promote the oxidation process, resulting in premature aging of the liver, but also a decrease in the length of the telomere, a DNA region at the end of each chromosome that is the main indicator of aging of the organism .

"Changes caused by the long-term consumption of sunflower oil and fish oil make the liver vulnerable to non-alcoholic steatohepatitis, a very serious disease that acts as a catalyst and for the onset of other serious liver diseases," says Quiles Morales.
