Why Do Astronauts Crave Spicy Food in Space?

It’s an odd question, but has a simple, chemistry-related answer. Astronauts “puff up” in space due to the lack of gravity, as the majority of bodily fluids are no longer confined to the lower limbs. This swelling impacts their taste buds, making it more difficult to taste duller flavors. However, things like spicy food have a strong flavor and thus can be tasted.

Because of this, astronauts have been known to crave Tabasco sauce when they’re up there, which makes sense. If you can barely taste anything, you’re going to need to really assault your taste buds with intense heat and flavor.
