The university are looking for 40 menopausal women aged under 75 and have type two diabetes. All the women will have to eat two bars of chocolate a day. Half the group will have "super-strength chocolate specially formulated by Belgian chocolatiers" and the others will have to eat regular chocolate as a placebo. All participants will have to be willing to undergo several tests to measure how healthy their hearts are.
Study coordinator Peter Curtis said: "A successful outcome could be the first step in developing new ways to improve the lives of people at increased risk of heart disease."
