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!
