A funny thing happens after you've been in space for a few days. The foods you liked on day one suddenly don't taste as good, and soon you're reaching for the hot sauce, even if you don't really like spicy foods. So why does it happen? Well, the short answer is that people lose their sense of smell in space. Astronauts have reported that food doesn't taste right after a few days on the International Space Station. Coffee is bitter, folks start craving sour and sweet foods, and everyone starts reaching for hot sauce.
