Expatriates who want to remain healthy to avoid having to make a claim on their international medical insurance cannot rely solely on a good diet.
According to nutritionist Yvonne Bishop-Weston, eating plenty of fruit and vegetables will not cancel out the effects of smoking and heavy drinking on the body.
"Plantarian foods are not an impenetrable magic force-field," she pointed out.
"They can reduce risk against factors caused by genetics, the environment and previous bad habits – they can help your body repair and strengthen your immune and digestive systems."
However, there is more evidence to suggest that smoking and alcohol will harm the health than there is to state that eating fruit and vegetables will save lives, Ms Bishop-Weston added.
Her comments come in light of research published in the European Heart Journal that found individuals who consume more fruit and veg have a reduced risk of dying from ischaemic heart disease, but this may be because they lead healthy lifestyles all round.
