Consumption of resveratrol, the compound often associated with the health benefits of red wine, can help prevent accumulation of fat in the liver which happens due to chronic alcohol consumption, according to a new study in mice.
Resveratrol is present in grapes, peanuts, berries and in red wine.The research found that resveratrol reduced the amount of fat produced in the liver of mice fed alcohol and, at the same time, increased the rate at which fat within the liver is broken down.
Chronic alcohol consumption causes fat to accumulate and can lead to liver diseases, including cirrhosis and fibrosis of the liver. It can also result in liver failure.
The study points to resveratrol as a possible treatment for alcoholic fatty liver disease, and as a way to prevent the disease in those who are at risk, but have not developed it.
The study, "Resveratrol alleviates alcoholic fatty liver in mice," was carried out by Joanne M. Ajmo, Xiaomei Liang, Christopher Q. Rogers, Brandi Pennock and Min You, all of the University of South Florida Health Sciences Center, Tampa.
The study appears in the American Journal of Physiology-Gastrointestinal and Liver Physiology, published by The American Physiological Society.

Resveratrol does the opposite - activating AMPK and SIRT1, and helping to clear out fat.

The researchers found, as they had expected, that resveratrol treatment increased the expression of SIRT1 and stimulated the activity of AMPK in the livers of mice fed alcohol. They further found that the increased expression of SIRT1 and AMPK led to reduction of sterol regulatory element binding protein (SREBP-1), activation of peroxisome proliferator-activated receptor gamma co-activator alpha (PGC-1a), elevation of circulating adiponectin, a hormone produced by fat cells, which helps control obesity and enhanced expression of adiponectin receptors in the liver, which increases the effectiveness of the circulating adiponectin.
The findings suggest that resveratrol prevents alcoholic fatty liver by coordinating molecules that control fat metabolism. This prevents accumulation of fat in the mouse liver by both reducing the production of fat and burning off the fat that is there. Interestingly, the combination of alcohol with resveratrol appears to enhance the positive effects of resveratrol, said Dr. You, the study's senior author.
