Obesity greater risk for fatty liver than moderate amounts of alcohol

30.05.2011
Being overweight and resistant to insulin constitute a greater risk for fatty liver than was previously thought, according to a study from Linköping University in Sweden that is now being published in the journal Annals of Medicine.

It has long been known that large amounts of alcohol can cause fatty liver. More recent research has shown that obesity and insulin resistance can also cause fatty liver, which in turn is closely associated with diabetes, high blood pressure, and cardiovascular disease.

Thus far it has been seen as sufficient to drink just over half a glass of wine per day for women and one glass for men to bring about fatty liver. Many people with fatty liver have therefore been asked by their physician to abstain from alcohol. If the liver condition nevertheless did not improve, physicians have assumed that the patient ignored their advice and drank too much alcohol anyway.

The two researchers professor Fredrik Nyström and assistant professor Stergios Kechagias at Linköping University are now showing that moderate amounts of alcohol everyday do not cause fatty liver. In their study, 44 individuals participated and were randomized to either abstain entirely from alcohol or drink one glass of red wine per day for women and two glasses for men for three months. Before and after the trial the subjects provided blood samples, and the fatty content of the liver was measured with state of the art magnetic resonance imaging.

“It turned out that the amount of fat in the liver was linked with obesity and insulin resistance and was almost not at all affected by the red wine. Specifically, after three months, none of the the wine drinkers had developed fatty liver or elevated liver transaminases” explains Stergios Kechagias, who is a liver specialist at LiU.

What’s more, the harmful LDL cholesterol was 16 percent lower at the end of the study in those who drank red wine compared with total abstainers.

“There is a strong correlation between moderate intake of alcohol and decreased risk of cardiovascular disease, and our data provides a mechanism for this since LDL-cholesterol was lowered to such a large extent” says Fredrik Nyström at LiU.

Fatty liver can lead to cirrhosis of the liver and is the most common liver ailment in the Western world. Roughly every fourth Swede presently has fatty liver.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
