A moderate consumption of coffee or tea - equivalent to four cups a day - could help prevent nonalcoholic fatty liver disease, popularly known as fatty liver, a disease associated with chronic inflammatory processes of the liver that if not treated correctly can degenerate into cirrhosis or cancer, and that is also related to an increased risk of developing diabetes.

A group of researchers led by Paul Yen and Rohit Sinha, of Duke University, in the United States, have conducted several experiments with cell cultures and in mice that had been fed a high-fat diet, in order to observe the reaction of fats stored in the liver cells of animals against the caffeine.

The conclusions of the research - which have been published in 'Hepatology' - point out that moderate intake of coffee or tea could be beneficial in preventing the progression of fatty liver.

It is the first study that has proven the mechanism of action of caffeine in liver lipids. The authors of the work have explained that the new data can serve as a basis for new research to develop drugs with the therapeutic properties of caffeine, but without its side effects, since an excess in the consumption of this substance increases the risk of suffering cardiovascular diseases.

However, moderate consumption of caffeine can have numerous benefits, since other studies have already shown their protective effects against diseases such as diabetes and hypercholesterolemia, as well as to improve the symptoms of Parkinson's and stop the loss of memory.
