Britain is an island between the North Sea and the Atlantic Ocean. For those who live near the sea, fish and shellfish have always been important. Before people had [coolers|fridges] to keep food cold and fresh, they started to keep fish from going [hard|bad] by salting, drying or smoking it. One thing which has changed is the [way|road] some people think about some foods. For example, shellfish like oysters were fairly cheap and quite ordinary. They were [famous|popular] with poor people because anyone could go to a beach and pick them up, for [money|free]. Today they are [harder|easier] to find and usually expensive. They have become [original|special].
In older days those who lived away from the sea first ate wild animals, but then they began keeping sheep, cows and chickens on [farms|factories]. Farmers grew fruit and vegetables. During the Middle Ages, from the eleventh to the fifteenth century, ships brought sugar, nuts and things from far away. When [farmers|sailors] went to foreign places, they brought back more kinds of food. At first only rich people could buy the things brought from overseas, but slowly they became cheaper and easier to find.
When gas and electricity came into people's houses, cooking became much [expensive|easier]. Thanks to fridges and freezers people could keep food much [longer|shorter]. The diet of many British people is quite different to that of their parents. Today we eat bananas and oranges and can buy them all the year round but it was very difficult to find them in Britain in the middle of the 20th century. Nowadays we have many more foods to [choose|select] from and new ways to cook them, like microwave ovens. But we have less time for shopping and cooking.
These days we drive to supermarkets where we can buy everything under one roof. Some forty years ago people walked to their nearest shops almost every day. They went to the baker's for [butter|bread], to the butcher's for meat, to the greengrocer's for fruit and vegetables and so on.
We also know more about health and the body today. Children grow up [studying|learning] that some foods are good for us while others, for example some sugars and fats, are bad. Some people have tried to change their [menu|diet] to eat healthier food and most shopping centres have health food shops which sell lots of different natural foods. Some people called vegetarians choose not to eat meat at all.
