Rediscovering the cure for scurvyMar 09 2010

Maciej Ceglowski tells the story of how the cure for scurvy was discovered, lost, and finally redsicovered, but not before it disrupted Robert Falcon Scott's 1911 expedition to reach the South Pole.

This is a good example of how the very ubiquity of vitamin C made it hard to identify. Though scurvy was always associated with a lack of greens, fresh meat contains adequate amounts of vitamin C, with particularly high concentrations in the organ meats that explorers considered a delicacy. Eat a bear liver every few weeks and scurvy will be the least of your problems.

But unless you already understand and believe in the vitamin model of nutrition, the notion of a trace substance that exists both in fresh limes and bear kidneys, but is absent from a cask of lime juice because you happened to prepare it in a copper vessel, begins to sound pretty contrived.
