Gatwick Airport introduces 'happy food' to restaurants

Between the check-in queues, grilling customs and immigration points and everything else in between, travellers can be left exhausted and a tad cranky by the entire ordeal.

Luckily, London's Gatwick Airport knows just how bad the toll can get on passengers and is set to do something to help the process a little - enter 'happy meals!'

Restaurants at the airport have updated their menus to include dishes designed to put travelers in a better mood.

According to CNN, Frankie and Benny's, for instance, has added a salmon citrus salad that promises to improve brain function, while Lebanese chain Comptoir's falafel and fattoush salad is meant to keep blood sugar levels steady.

Explaining the concept, nutritionist Jo Travers said:

"There are certain foods that will help the 'happy' chemicals in your brain to keep flowing. Two key players are the neurotransmitters serotonin and dopamine, along with amino acids tryptophan and theanine, which can contribute to the creation of serotonin, known to most as 'happy hormones'."

He further explained that low levels of these chemicals can cause fatigue in addition to lowering existing levels of serotonin, while a deficiency of Omega 3, can lead to fatigue and mood swings.

The new meals will reportedly be on trial at Gatwick for a month. As for the success of the move, only time will tell.
