The medicine's in the (wine) bottle
Red wines are rich in polyphenols, in particular epicatechin gallate, also found in green tea, and ellagic acid, which is found in many fruits
Some red wines contain such high levels of polyphenols that a single glass has equivalent bioactivity to several daily doses of an anti-diabetes drug, say Austrian scientists.
Polyphenols play a key role in the health benefits of wine by acting as antioxidants that prevent cell damage, but the other possible effects of these chemicals are not yet fully understood. Now, a group led by Alois Jungbauer from the University of Natural Resources and Life Sciences, Vienna, Austria, have shed light on this area by examining polyphenols in eight Austrian red wines. They assessed polyphenol activity towards a receptor called PPAR-gamma (peroxisome proliferator-activated receptor gamma). This receptor is present in many tissues in the body, and is primarily involved in the development of fat cells, in energy storage, and in modifying lipid and glucose levels in the blood, making it a key target for drugs for cardiovascular and metabolic diseases.
