Limes
Limes may be most famous for their historical benefits to sailors. Limes are packed with Vitamin C and were eaten on ships to prevent scurvy, a disease caused by that vitamin deficiency. In the eighteenth century, all British naval ships assigned to long journeys were required to carry limes. The nickname 'limeys' for British sailors has continued to this day.
Limes were originally grown on the Indian subcontinent and were popularized in Europe about the time of the Crusades. In the United States, limes were established in what is now named Florida by the sixteenth century. Today limes are grown in Florida, the Southwest, and California.
