You are what you eat—that’s true even after your bones have spent 200 years buried in the dirt. A new study using old bones from 18th century British sailors confirmed the naval diet: lots of biscuits, more protein than the average landlubber, and the same damn things sailors ate for the previous 200 years.
The Victualing Board actually kept meticulous records of a sailor’s official rations: 1 lb of bread and 1 gallon of beer per day (!), plus 1 lb of pork twice a week, 2 lbs of beef twice a week, or butter and cheese the other three days. But when the going got tough out in the middle of watery nowhere, did sailors actually get their rations? Yes, it seems, based on an analysis of nitrogen isotopes extracted from the bones of 80 sailors. The elevated levels of nitrogen suggested that sailors did get as much beef and pork as the Victualing Board recorded. And despite being at sea, they didn’t seem to eat much fish.
