Healthy Eating-----What is a healthy diet?

SEFC Book 1 B

Unit 15 Lesson 58

Every person needs water and a diet of healthy

foods. These foods should contain some fat, some

fibre, a little salt and so on.

Unit 15 Lesson 58

Reading WHAT IS A HEALTHY DIET

Paragraph 1

People need energy to live. They eat different kinds of

Food which change into energy. The energy is measured

in calories. Even when you are asleep, you are using

energy —about 65 calories an hour. While you are at

school, or walking home, your body is burning up 100

calories an hour. When playing football or basketball,

you might be using 400 calories an hour. On Sports Day,

during the relay race, you will use most of all, perhaps as

much as 650 calories an hour.

Paragraph 2

The Chinese diet is considered to be the healthiest

in the world. It contains a lot of fruit and green

vegetables. It is rich in fibre and low in sugar and

fat. The Chinese eat less sugar than many other

countries in the world. That is why lots of people

in China have healthy white teeth.

Paragraph 3

People in the Western world do not eat such healthy foods. They eat too much fat and sugar and don’t take enough exercise. Because of this, they put on weight very easily. Their diet contains a lot of fat in the form of potato crisps, potatochips, butter, cream and chocolate. They eat a lot of sugar in the form of cakes, soft drinks, sweets and so on. The result is that many of them becomefat. And some have bad teeth. In some parts of Britain, one person in ten, by the age of thirty, has no teeth left!
