Scurvy
Scurvy is a disease resulting from a deficiency of vitamin C. Scurvy often presents initially with fatigue, followed by formation of spots on the skin, spongy gums, and bleeding from the mucous membranes. Spots are most abundant on the thighs and legs, and a person may look pale, feel depressed, and be partially immobilized. As scurvy advances, there can be open, suppurating wounds, loss of teeth, yellow skin, fever, neuropathy and finally death from bleeding.While today scurvy is known to be caused by a nutritional deficiency, until the isolation of vitamin C and direct evidence of its link to scurvy in 1932, numerous theories and treatments were proposed, often on little or no experimental data. This inconsistency is attributed to the lack of vitamin C as a distinct concept, and an inability to reliably link different foods (notably present in fresh citrus, watercress, and organ meat) to scurvy. An additional concept required to understand scurvy was the degradation of vitamin C by exposure to air and copper and other transition metal salts such as those of iron, thus changing the links of foods to scurvy over time. Vitamin C is required for the synthesis of collagen in humans. The chemical name for vitamin C, ascorbic acid, is derived from the Latin name of scurvy, scorbutus, which also provides the adjective scorbutic (""of, characterized by or having to do with scurvy"").Treatment by fresh food, particularly citrus fruit, was periodically implemented, as it had been since antiquity. However until the 1930s, treatment was inconsistent, with many ineffective treatments used into the 20th century. It was a Scottish surgeon in the Royal Navy, James Lind, who first proved it could be treated with citrus fruit in experiments he described in his 1753 book A Treatise of the Scurvy, though following a failed trial with extracted lime juice, it would be 40 years before effective prevention based on fresh produce became widespread.Scurvy was at one time common among sailors, pirates and others aboard ships at sea longer than perishable fruits and vegetables could be stored (subsisting instead only on cured and salted meats and dried grains) and by soldiers similarly deprived of these foods for extended periods. It was described by Hippocrates (c. 460 BC–c. 380 BC), and herbal cures for scurvy have been known in many native cultures since prehistory. Scurvy was one of the limiting factors of marine travel, often killing large numbers of the passengers and crew on long-distance voyages. This became a significant issue in Europe from the beginning of the modern era in the Age of Discovery in the 15th century, continuing to play a significant role through World War I in the early 20th century. In infants, scurvy is sometimes referred to as Barlow's disease, named after Sir Thomas Barlow, a British physician who described it in 1883. However, Barlow's disease may also refer to mitral valve prolapse. Other eponyms for scurvy include Moeller's disease and Cheadle's disease.Scurvy does not occur in most animals as they can synthesize their own vitamin C. However, humans and other higher primates (the simians—monkeys and apes—and tarsiers), guinea pigs, most or all bats, and some species of birds and fish lack an enzyme (L-gulonolactone oxidase) necessary for such synthesis and must obtain vitamin C through their diet. Vitamin C is widespread in plant tissues, with particularly high concentrations occurring in cruciferous vegetables, capsicum fruit including chili and all colours of bell peppers, citrus fruits (oranges, lemons, limes, grapefruits), and almost all fruits including botanical fruits that are culinary vegetables, like tomatoes. The fruit with the highest concentration of vitamin C is the Kakadu Plum with nearly 3000 mg per 100g. Cooking significantly reduces the concentration of vitamin C.
