The bars have been developed by researchers at the Cadbury Schweppes Global Science Centre, in partnership with the Carnegie Research Institute at Leeds Metropolitan University, to provide mountaineers with the essential energy and
nutrients needed to survive in extreme conditions.
They will be used by the British Army in an attempt next March to be the first British mountaineers to scale Everest via the notorious West Ridge. One has been made to be eaten at an altitude of up to 8,000m above sea level, where temperatures can drop as low as -40 degrees Celsius, and contains refined carbohydrates, vitamins and protein. A second has been designed to be eaten at the team’s base camps
