(Thursday, June 2, HealthDay News) - obesity and insulin resistance are a greater risk than moderate consumption of alcohol fatty liver disease, according to a new study that found drinking small amounts of red wine does posed no greater risk for the development of the condition.
For their study, published online on May 23, in the annals of medicine Swedish researchers asked 44 people either refrain from alcohol or drink (women) one or two glasses (men) of red wine per day for three months. At the beginning and the end of three months, investigators collected blood samples and conducted MRI to measure the content of fat in livers of participants.
"It proved that the amount of fat in the liver was connected to the resistance of obesity and insulin and was almost not at all affected by red wine." Specifically, after three months, none of the wine drinkers had developed fatty liver or elevated liver transaminases, "Dr. Stergios Kechagias, a specialist of the liver at Linkoping University, said in a press release from the Swedish Council for research.
In addition, the study showed a decrease of 16 per cent of the levels of bad cholesterol LDL among those who drank red wine. "There is a strong correlation between moderate alcohol consumption and reduced risk of cardiovascular disease and our data provides a mechanism to do this since the LDL cholesterol was reduced to a great extent," Dr. Fredrik Nystrom, Professor at Linkoping, found in the press release.
Because it is known that the large amounts of alcohol contribute to liver disease, it has long believed that even moderate consumption may have a harmful effect.
Foie gras, which is associated with diabetes, hypertension and cardiovascular disease, can lead to cirrhosis of the liver, noted researchers.
