Scurvy is a disease caused by a deficiency of vitamin C, which is essential for the body to produce collagen, a protein that helps maintain healthy skin, blood vessels, and connective tissues. People who do not get enough vitamin C may experience symptoms like fatigue, swollen gums, and joint pain. Historically, sailors were particularly affected by scurvy during long sea voyages when fresh fruits and vegetables were scarce. To prevent scurvy, it's important to include foods rich in vitamin C in your diet, such as citrus fruits, strawberries, and leafy greens. Treatment typically involves increasing vitamin C intake, either through diet or supplements, leading to a quick recovery.
