Expatriates who are concerned about their appearance may be interested to know that a suntan isn't necessarily the best way to look good.
In fact, recent research conducted by Bristol University has revealed that eating the recommended five portions of fruit and vegetables a day is the most effective way to achieve a health golden glow.
Lead researcher Dr Ian Stephen explained that people who ate more portions had a golden yellow skin colour.
Furthermore, they were shown to have a higher presence of cartenoids, which are yellow and red antioxidants thought to play a role in the immune system and fertility.
Volunteers were then asked to make the simulated faces look as healthy as possible by adjusting the facial colour.
When given the choice between colour enhanced by a suntan and colour enhanced by carotenoids, participants were found to prefer the latter.
Expatriates living in sunny climates might want to bear this research in mind when considering their health and appearance.
