Expatriates often have to spend a lot of time waiting at airports and it is important that they can get a well balanced meal for their health and wellbeing.
A survey carried out by the Physicians Committee for Responsible Medicine (PCRM) has found that the majority of airports in the US have seen their food offerings improve in terms of healthy eating.
In order to establish which of the 18 airports involved performed the best and worst, the PCRM used the simple formula of dividing the amount of restaurants with a healthy option by the total number of restaurants.
The healthiest airport was found to be Newark Liberty International Airport with Chicago O'Hare International Airport coming out as the most improved.
Healthy options available at Newark include a falafel sandwich, hummus wrap and seaweed salad, as well as asparagus rolls, sushi and tofu.
In contrast, San Francisco International Airport was found to have dropped 19 points since last year, meaning there is not as much choice for healthy travellers as there once was.
