The story of Surgeon-Captain T. L. Cleave compiled, written and introduced by Adrian Mourby with Few people know that while HMS King George Vwas steaming after the Bismarck in the Battle of the North Atlantic, history of a different kind was being made on board in the surgery of the ship's doctor, Captain Cleave. For he was experimenting on officers and men of the Royal Navy - from the Admiral downward - to see if bowel problems could be overcome by the application of more fibre in the diet. The result of Captain Cleave's wartime experiments has had far-reaching effects on our concept of a healthy diet today. Producer BRIAN MILLER BBCBristol
