(Newkerala) -Lovers of red wine were delighted when it was found to contain resveratrol - a compound supposed to improve health and maybe even lengthen life.But studies have insisted that to see benefits, you would need to consume large amounts of the compound - more than is found in a bottle of wine. Now a new study suggests we could get the equivalent of large resveratrol doses from pills we already have- a class of drugs that are being tested for use as treatments for Alzheimer's and Parkinson's disease.
