Darn limeys. :) [Mansplaining note: British sailors were given the nickname "limey" due to the use of limes to ward off scurvy - see https://en.wikipedia.org/wiki/Limey - note that limes have 1/4 the vitamin c of lemons and the processing and storage of lime juice destroyed much of the remaining vitamin c]
A relative heard of a college student who lived on nothing but Kraft Dinner and Red Bull. This student eventually had to get treated for scurvy.
I was thinking about testing volunteer Uyghurs, Kazakhs and Kyrgyz but we have to liberate them first. They are deficient in just about everything. I'm skipping ahead.
