UK-based studies suggest that an antioxidant found in red wine could have beneficial effects on health by reducing the risk of stroke and heart disease
Several studies suggest that resveratrol, a polyphenolic antioxidant found in grape skins and so red wine, could have beneficial effects on health by reducing the risk of stroke and heart disease. Now, Richard Hoffman and Conny Johansson of the University of Hertfordshire have used high-performance liquid chromatography (HPLC) and liquid chromatography coupled to mass spectrometry (LC-MS) to do the first systematic study of resveratrol levels in a selection of supermarket wines.
'We assume that all red wines are the same', says Hoffman, 'but we have found this is certainly not the case because the levels of resveratrol vary between labels'.
The researchers say they could recommend the healthiest bottle of red and are planning to work with wine suppliers and retailers to have health indicators added to bottles.
