Three glasses of champagne a day could help ward off brain disorders such as dementia and Alzheimer's disease, say researchers. A compound found in the black grapes pinot noir and pinot meunier, both of which are used for champagne, helps stave off forgetfulness.Jeremy Spencer, a biochemistry professor at Reading University, said: "Dementia probably starts in the 40s and goes on to the 80s. It is a gradual decline and so the earlier people take these beneficial compounds in champagne, the better."It is not the first time scientists have identified health benefits in champagne. In 2009, the same team found that it was as good for the heart as cocoa or red wine polyphenol antioxidants, which are believed to reduce the effects of cell-damaging free radicals in the body.The memory aid found in champagne is a different compound, phenolic acid.In the latest study, researchers found that the drink provoked a noticeable boost to spatial memory. ..
