Gatwick Airport Introduces Meals to Make Fliers Happier

— -- Arriving at the airport isn't usually an experience travelers equate with a positive mood.

But fliers traveling from London's Gatwick Airport will find mood-boosting food available, designed specifically to make fliers happier before boarding.

The airport teamed up with nutritionist Jo Travers to become the first airport in the world to introduce a happiness guide on restaurant menus. Designed to help travelers have a "happy holiday from the moment they arrive at the airport," a spokesperson told ABC News, Gatwick has identified roughly two dishes at eight restaurants that boost serotonin.

“Happiness is a complex thing, but there are certain foods you can eat that will help the ‘happy’ chemicals in your brain to keep flowing," said Travers "Two key players are the neurotransmitters serotonin and dopamine, along with amino acids tryptophan and theanine which can contribute to the creation of serotonin which is known to most as 'happy hormones.' Low levels of these chemicals can cause fatigue in addition to lowering existing levels of serotonin. Similarly, a deficiency of Omega 3, can lead to fatigue and mood swings."

Happy dishes will be identified by yellow happy face emoji icons on the menu.

For travelers not passing through Gatwick, Travers shared food that make people happy.

Top 10 ingredients that can make you happy:

1. Salmon

2. Tuna

3. Bananas

4. Oats

5. Citrus fruit

6. Spinach & Kale

7. Sesame seeds

8. Green tea

9. Chickpeas

10. Soy and soy products like miso

“People often don’t realise how much of an impact what they eat can have on their mood," said Travers, which can be particularly important if you’re about to take a long flight.”
