Expatriates enjoying life in sunny climates might want to look into eating more fresh fruit.
Recent research has suggested that brightly coloured foods, red berries in particular, are very effective at protecting skin.
Sally Penford, education manager for the International Dermal Institute, explained that a lot of these foods provide the body with "great antioxidants".
"Any highly coloured fruit, pomegranates, red berries, blueberries, anything with a strong colour in nature is usually rich in antioxidants that will help to protect your skin against free radical damage, and free radicals are something that contribute towards the aging process," she added.
Expatriate medical insurance customers might be particularly interested to hear that fresh fruit can improve a person's appearance more than a suntan.
Indeed, research conducted by the University of Bristol revealed that eating more fresh fruit and vegetables increases skin colour through carotenoids, which are red and yellow antioxidants commonly found in fruit and vegetables.
A group of volunteers asked to adjust computer images of faces to make them look as healthy as possible opted for skin colour that was enhanced by carotenoids over skin that was tanned by the sun.
