Summary:
In an international study, with researchers from Cambridge and Switzerland, researchers reviewed a Mediterranean-style diet to see if it may lower the risk of developing fatty liver disease.
Fatty liver, defined as fat accumulation of more than 5% of liver volume, is common especially among obese and diabetic individuals. Fatty liver is the first stage for non-alcoholic fatty liver disease (NAFLD), which is a major cause of liver disease worldwide, and may also predispose to higher risk of cardiovascular diseases.
The Mediterranean diet is thought to be beneficial but research was limited to people with established fatty liver disease. Researchers
In 2288 study participants without NAFLD at baseline, when we assessed their dietary habits and scaled their levels of adherence to the well-established Mediterranean diet. After an average of 5.3-years of follow-up in the study, we tested for the presence of fatty liver disease based on two indices called “fatty liver index” and “NAFLD score”.
Results showed that those who adhered more to the Mediterranean diet had lower risk of developing new-onset fatty liver disease based on fatty liver index.
