 Whenever you are on a flight, do you end up rather feeling let down by the quality of food? Well, it is not the case that the airplane is employing the most horrible cooks on earth. It may be better explained as being linked to the way in which the altitude and the pressure inside the plane could be impacting our sensor. In fact, it is believed that our sense of smell goes down by 20-40% when we are on the plane at that altitude and pressure. And when you consider the role of smell in how we taste something, it will make a huge difference. So the next time you are on the flight and you are offered something to eat, don't turn away your nose because it is your nose that may be at fault.
