Diet with high levels of fructose, trans fats leads to significant liver disease

Washington, June 24 (ANI): A diet with high levels of fructose, sucrose, and of trans fats not only increases obesity, but also leads to significant fatty liver disease with scar tissue, a new study has found.

"We've developed a mouse model that is very close to human disease, allowing us to better understand the process involved in the development and progression of obesity-related fatty liver disease," Rohit Kohli, a gastroenterologist at Cincinnati Children's Hospital Medical Center and the study's main author.

The study also includes preliminary data on a simple blood test for a biomarker that differentiates the stages of disease in this model. Physicians currently monitor the progression of fatty liver disease by taking liver biopsies, which are invasive procedures.

The study, which was conducted with scientists from the Metabolic Disease Institute at the University of Cincinnati, is published online in the journal Hepatology.

The study was conducted in mice, some of which were fed a normal diet of rodent chow and some a 16-week diet of fructose and sucrose-enriched drinking water and trans-fat solids. Their liver tissue was then analyzed for fat content, scar tissue formation (fibrosis), and the biological mechanism of damage.

This was done by measuring reactive oxygen stress, inflammatory cell type and plasma levels of oxidative stress markers, which are known to play important roles in the development of obesity-related liver disease and its progression to end-stage liver disease.

The investigators found that mice fed the normal calorie chow diet remained lean and did not have fatty liver disease. Mice fed high calorie diets (trans-fat alone or a combination of trans-fat and high fructose) became obese and had fatty liver disease. (ANI)
