Zest

Between 1500 and 1800, it has been estimated that scurvy killed at least two million sailors.
In 1593 Admiral Sir Richard Hawkins advocated drinking orange and lemon juice as a means of preventing scurvy
The eradication of scurvy from the Royal Navy in the 1790s was finally due to the Navy's Sick and Hurt Board insisting that lemon juice was issued to sailors. This led to remarkable health improvements and consequently played a critical role in naval battles, notably the Battle of Trafalgar.
