Scurvy is a disease caused by a lack of vitamin C in the diet. It was historically common among sailors and pirates who went long periods without fresh fruits and vegetables. Symptoms of scurvy include bleeding gums, bruising easily, and fatigue. While almost anyone can develop scurvy by not consuming enough vitamin C, it was especially prevalent in sailors and pirates due to their diets lacking this essential nutrient during long sea voyages before modern refrigeration. May 2nd is recognized as Scurvy Prevention Day to promote consuming citrus fruits and other vitamin C sources to avoid this malady.
