     If you don't want people to know too much about you, then you had better keep your fridge contents

secret according to a British market research document released last week.

     Researchers peered (凝视) into the fridges of 400 people in Britain and compared the contents with the

owners' lifestyles. They claim to be able to classify the nation's people by fridge contents.

     They say those people can be divided into five categories: "nutrition nerds", "food faddies", "martyr

mums", "fast food fanatics" and "restaurant regulars".

     "Nutrition nerds" care much about what they put into their bodies. Their fridges are stocked with fruit,

vegetables and healthy meat. People in this category tend to be highly organized and usually work in law or

accountancy. The vast majority are single, but if they have a partner, that person will be similar.

     A fridge full of vitamins-enriched juices implies its owner works in media or fashion. They tend not to

eat the foods they buy. Known as the "food faddies", they just want to be seen as buying the latest important

things.

     A fridge filled with everything from steak to frozen fish suggests the "martyr mum". Her fridge tends to

be stocked with every kind of product, except what she herself would want. This fridge hints at difficulty

balancing family and work life.

     "Fast food fanatics" always buy mineral water for soda pop (汽水); the nearest they will get to fresh

fruit is tomato sauce. Their fridges hint at someone who works hard and plays hard, also, someone who is

not into long term planning.

     Finally, a fridge filled with nothing more than a bottle of white wine and some sparkling mineral water

implies an owner who is single, lives in a big city and enjoys the finer things in life. The fridge is empty

because this person regularly eats in restaurants.
