Now chocolate is good for you!: "For centuries chocolate has been regarded as a vice but now it could become a life-saver. A leading professor is to administer confectionery to heart patients to test its health benefits. Scientists believe there is growing evidence that eating dark chocolate can relax the blood vessels, help to prevent blood clotting and stave off heart attacks. To test the thesis Roger Corder, professor of experimental therapeutics at Barts and The London, Queen Mary's School of Medicine and Dentistry, is applying for ethical approval for a trial of dark chocolate on 40 patients with cardiovascular disease. Corder believes there will soon be enough evidence that flavanol molecules found in dark chocolate fight heart disease for doctors to recommend a daily portion of about four squares as part of a healthy diet."
