The expedition succeeded in combating incipient scurvy through a fresh seal meat diet, and Scott recommended it for future polar expeditions. This was despite the medical profession being ignorant of the causes of the disease. At that time it was known that a fresh meat diet could provide a cure, but not that lack of fresh meat or other fresh food containing the as yet undiscovered vitamin C was a cause. Thus, fresh seal meat was taken on the southern journey "in case we find ourselves attacked by scurvy", On his 1907–09 "Nimrod" expedition Shackleton also avoided the disease through careful dietary provision, including extra penguin and seal meat. However, Lieutenant Edward Evans almost died of presumably self-inflicted scurvy during the 1910–13 "Terra Nova" Expedition, and scurvy was particularly devastating to Shackleton's marooned Ross Sea party during 1915–16. It remained a danger until its causes were finally established, some 25 years after the "Discovery" Expedition.
