Lemons and limeys Certainly, the diet offered by Captain James Cook (Report, 30 November) was sensible with regard to the prevention of scurvy. However, James Lind, the naval surgeon, had published his detailed Treatise of Scurvy 23 years before, in 1753. Among other recommendations, derived from the first-ever clinical trials (conducted at sea) he principally advocated the use of fresh lemons or lemon juice. Lack of interest by the Admiralty led to his recommendations being ignored for over 40 years. Only then, after the forceful promotion of Lind's thesis by the naval surgeons Thomas Trotter and Gilbert Blane, were the fleets appropriately supplied, and scurvy was eradicated almost overnight. Soon, however, for perverse commercial reasons, the Admiralty espoused the use of limes (not recommended by Lind) and scurvy returned to plague sailors and others until the discovery and understanding of vitamins after the first world war.David HarvieAuthor of Limeys: The Conquest of ScurvyNutritionNutritionMedical researchHeritageguardian.co.uk © Guardian News & Media Limited 2009 | Use of this content is subject to our Terms & Conditions | More Feeds guardian.co.uk |
