Astronauts must go without many popular foods and beverages on the International Space Station, including soda — the carbonation goes wacky in space and could wreak havoc on the digestive system; perishable items, because food poisoning would be pretty terrible in space; and alcohol, because it could damage water recovery equipment and impair astronauts' judgment.
And some have been staples since the early missions. Tang, a beverage nearly synonymous with spaceflight, remains popular among astronauts today. What you won't hear about as often — shrimp cocktail. "Shrimp cocktail has almost forever been [one of] their favorite foods," Bourland says (and Kloeris agrees).
