Latest study has unveiled that drinking red wine or red grape juice in moderation can help in burning fat. The study has been published in the Journal of Nutritional Biochemistry. Neil Shay, biochemist and molecular biologist at the Oregon State University in the United States stated “We did not expect, and we did not find, these compounds to improve body weight.” Red wine or juice augments the fat burning ability of liver. In overweight people, it might also improve liver function. However, the study does not indicate that drinking wine leads to miraculous weight loss. Shay commented “If we could develop a dietary strategy for reducing the harmful accumulation of fat in the liver, using common foods like grapes, then it would be good news.”
For the study, human liver and fat cells grown in the lab were exposed to the extracts of four natural chemicals found in Muscadine grapes. Muscadine grapes are a dark-red variety native to the south-eastern part of the United States. Ellagic acid was one of the components, which dramatically slowed the growth of existing fat cells and also the formation of new ones. The compound also enhanced the metabolism of fatty acids in liver cells.
The researchers conducted another trial in which the diets of obese mice were supplemented with extracts from Pinot noir grapes. Normal diet with 10 percent fat was given to some of the mice and the rest were given a diet containing 60 percent fat. The latter constitutes the unhealthy diet which contributes to obesity. The trial continued for 10 weeks and the mice which had high percentage of fat in the diet developed fatty liver and diabetic symptoms. These are the same metabolic consequences which can be observed in overweight and sedentary people. However, it was observed that the chubby mice which were given the extracts had reduced accumulation of fat in their liver. As compared to those who only consumed high –fat diet, those who also consumed the extracts had lower blood sugar. Ellagic acid was found to be very beneficial as it reduced the blood sugar of high-fat-fed mice to the levels of lean, normally-fed mice.
Apart from this, red wine provides a number of other benefits like fighting cavities and protecting against cancer. Ashok K Shetty, a faculty member in the Texas A&M Health has mentioned that red wine contains a compound which helps to prevent age-related memory loss.
