The shrimp cocktail on the space shuttle must really have been something. On a two-week flight in 2006, astronaut Mark Polansky asked to have it on his menu every day. For breakfast. As well as lunch and dinner.
And he wasn't the first. Astronauts, as a group, probably have tastes much like the earthbound among us, but in space things change. For lack of gravity, fluids in the body are no longer pulled down toward one's feet. There's no such thing as post-nasal drip in weightlessness.
