Where’s the beef?

It’s Saturday afternoon and you are at the shops with your friends. You' ve been shopping all morning and you' re starving! But where are you going to eat? There’s а good chance that you' ll go to а fast food restaurant like Pizza Hut, Burger King or Wendy’s. The biggest problem is choosing one because there are so many.

In the last thirty years fast food has become а major part of our diets. Fast food is cheap, easy to find and easy to eat. You can even eat а burger while you are

driving. Try doing that with а bowl of spaghetti! Families stop at Pizza Hut on the way home from а day trip. Teenagers meet at McDonald s for а burger at lunchtime. Busy office workers buy tasty sandwiches at Subway. It s so quick and easy.

But is fast food healthy? Richard Benton is а nutritionist and he says that fast food can be healthy food. 'Most fast food restaurants have healthy choices like salads and lean chicken sandwiches,' he says. 'Fast food is ОК as long as you don' t eat too much of it.'

People who do eat too much fast food can have health problems. In the United States, 300,000 people а year die from illnesses related to obesity. Twenty per

cent of children in the United States are overweight. The problem has spread as Western fast food has become popular in countries like China, India and Japan. Five to ten per cent of Chinese children are now overweight.

Also, some fast foods contain а lot of fat and sugar. Some health experts believe that high-fat and high-sugar foods change children s behaviour. А recent

survey in Japan found that badly behaved children ate more fast food than well-behaved children.

The good news is that fast food is changing. It is becoming healthier. Thai, Turkish, Japanese and Filipino fast food is becoming popular in the United States.

You can have а quick snack in Elephant Jump (Thai), Jollibee (Filipino) or Yoshinoya (Japanese) if you don' t want а pizza.
