Extra-virgin olive oil may combat diseases
Acompound commonly found in extra-virgin olive oil can significantly reduce symptoms of insulin resistance and non-alcoholic fatty liver disease —the negative effects of a high-fat diet, a study has found.
Hydroxytyrosol is a polyphenol found in extra-virgin olive oil, which is known to have antioxidant properties and may be beneficial to health.
“Our research shows that hydroxytyrosol exerted a protective effect on the liver of a mice, that was fed on a high-fat diet, ” said lead author Rodrigo Valenzuela from the University of Chile. The study showed that hydroxytyrosol was able to reduce liver enzymes that are linked to an imbalance in the fatty acid composition of the liver, brain and heart.
The results revealed that adding a relatively low dose of hydroxytyrosol to the diet was able to reverse oxidative stress, which is linked to fatty liver disease. In addition, it also lowered the increase in levels of lowdensity bad cholestrol.
