We've all heard the running jokes that airline food is bland and tasteless, but some research shows that it might not actually be the food that's at fault. A 2010 study conducted by Lufthansa suggests that when you fly, the dry air in the plane can cause your nasal mucus to evaporate and your membranes to swell, both of which can impact your taste buds. In the same study, researchers found that when we're in the air, our perceptions of sweet and saltiness can drop by as much as 30 percent. No wonder our food tastes bland when we're flying.
