This text deals with ...
1) a healthy diet.
2) an unusual band.
3) the most important food.
4) thinking about animals.
5) the question of danger.
6) some meal traditions.
Five facts about food
A) If you eat more than you need, the extra calories turn into fat; if you eat less
than you need, the body burns fat to get energy and you lose weight. One way of
loosing weight is by dieting — eating less. Another way is to go on eating as
usual, but then you must take more exercise. But start doing it gradually. Don't
try to lose a lot of weight fast. It doesn't usually work and it can be dangerous.
B) In some countries bread is an important part of everyday food. When people
sit down for a meal, there is always bread on the table. In countries where
people eat a lot of bread, the word “bread" is used to talk about some other
important things. In English-speaking countries it often means “money". In
Russia people talk about their jobs as their bread and butter, and the person
in the family who brings home the money is called the "breadwinner".
C) Nowadays Eskimos eat and love fast food and pizzas and hamburgers. But
some of them continue to live as hunters and fishermen. They wear traditional
costumes and eat traditional food like deer and polar bear. Every day Jack
Ikummag works in a shop, but at the weekend he takes his gun, drives his
snowmobile out of his village and shoots a deer. Then he cooks it with lots of
spices and invites his relatives and friends to share the meal.
D) There is a special orchestra in Vienna. All the instruments are made of carrots,
cucumbers and pumpkins. The lead musician plays a horn made from a
cucumber, a green pepper and a carrot. The musicians can play everything
from classical music to jazz. And nothing is wasted: after the performance a
cook makes a big pot of soup or stew for the musicians and audience to eat.
E) More and more people nowadays become vegetarians. A diet free from meat
has all the vitamins, minerals and protein you need. And a vegetarian diet is
not only healthier but it is also kinder. We know that animals grown for meat
production are kept in special factory farms. Pigs and chickens are in boxes
where they cannot even turn around!
