The saying goes that an apple a day keeps the doctor away but now scientists at the University of Glasgow are looking into whether a pint of cider could have the same effect. Researchers have discovered that English cider apples have high levels of phenolics antioxidants linked to protection against stroke, heart disease and cancer and are working with volunteers to see whether these health benefits could be passed onto cider drinkers.

In the next few weeks 12 volunteers will each drink a pint of cider, while avoiding all other dietary sources of antioxidants, to give the research team a unique insight into how phenolics are absorbed and metabolised by humans. The research is part of a project funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and the National Association of Cider Makers.

Serena Marks, who is leading the study, explains: "Previous research suggests there may be an association between phenolics and protection against some serious diseases, so we are trying to find out how we get phenolics from our diet. We know that apples are high in phenolics and our research shows that cider apples have a higher phenolic content than dessert apples."

The cider industry has long been interested in phenolics, because these compounds play an important role in the taste and colour of cider, but Marks hopes her research will show that phenolic levels also have a beneficial health role.

So far Marks and her colleagues have looked at the phenolic levels of 19 varieties of English cider apple, 35 varieties of cider and one variety of dessert apple to analyse how and why levels differ and to understand the effects that the cider making process has on the final phenolic content of cider.

They have found that some varieties of apple and some types of cider have higher levels of phenolics than others. Factors that may affect phenolic concentration include the age of the fruit, light exposure, gro
