There is no shortage of research into the health benefits of coffee. Last year there were findings suggesting coffee is linked with longevity. In contrast a study by Vanderbilt University said drinking two or more cups a day, of coffee or tea, might increase the risk of lung cancer. The research was presented to the annual meeting of the American Association for Cancer Research. Dr Kathryn Bradbury is a senior research fellow at the University of Auckland who is an expert in food and nutrition intake in relation to cancer incidence. She joins the show to go through the findings of the research relating coffee and tea consumption to cancer.
