An English airport joined forces with a nutritionist in an effort to provide a mental boost to potentially harried passengers.
Gatwick Airport, some 30 miles south of London, will spend the next month testing new airport meals concocted with the help of Jo Travers.
Travers told CNN that offering foods with critical neurotransmitters and amino acids can bolster the creation of "happy hormones."
"Low levels of these chemicals can cause fatigue in addition to lowering existing levels of serotonin," Travers added. "Similarly, a deficiency of Omega 3, can lead to fatigue and mood swings."
One restaurant in the airport offers a salmon citrus salad designed to promote brain function, while a Lebanese chain aims to maintain blood sugar levels with its falafel and fattoush salad.
CNN reports that the effort is part of a growing trend of health-conscious food offerings across the airline industry.
Airports in the Netherlands and Belgium, meanwhile, now allow passengers to get a workout in with indoor bikes that also serve as charging stations for electronic devices.
