Blame dry air and high-sodium foods.
The science:
A new study found that the average airline meal contains upwards of 800 milligrams of sodium, which is more than 40 percent of the daily limit set by the World Health Organization.
In an airplane's dry conditions, eating too much salt is more likely to cause bloating and dehydration.
Expert insight:
Previous research shows in-flight factors like altitude, cabin air pressure, and low humidity levels can dull your senses.
In fact, food may taste up to 30 percent less flavorful in that environment than it does when you’re grounded, says study author Charles Platkin, Ph.D., MPH, executive director of the NYC Food Policy Center at Hunter College. Saltiness and sweetness are the two specific tastes that are most affected. In turn, airlines may add extra sodium and sugar to their meals to boost flavor.
The bottom line:
If you end up eating an in-flight offering, pair it with a banana, orange, or other high-potassium snack, Platkin says. The electrolyte helps flush excess sodium from the body.
