Every person needs water and a diet of healthy foods. These foods should contain some fat, some fibre, a little salt and so on.
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 650calories an hour. 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.
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, potato chips, 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 become fat. And some have bad teeth. In some parts of Britain, one person in ten, by the age of thirty, has no teeth left!
什么是健康的饮食？
每个人都需要水和健康的食物。这些食物应该含有一些脂肪和纤维，还应该含有一点盐和其他成分。人要生存就需要能量。他们吃各种各样的食物，这些食物转变为能量。这种能量以卡来计算。即使你睡着时，你也在消耗能量——每小时约65卡，你在学校上课或走路回家时，你的身体每小时要消耗100卡。当你踢足球或打篮球时，你可能每小时要消耗400卡。开运动会时，在接力赛跑中，你消耗的热量最多可能每小时多达650卡。 中国的饮食被认为是世界上最健康的饮食。它包括许多的水果和绿色蔬菜。它纤维丰富，糖和脂肪少。
中国人吃糖比世界上其他许多国家都少。这就是许多中国人都有着健康洁白的牙齿的原因。
　　西方人不吃这样健康的食物。他们吃过多的脂肪和糖，又没有足够的运动。因此，他们的体重很容易增加。他们的食物有油炸土豆片、油炸土豆条、黄油、奶酪和巧克力，这些食物都含有大量的脂肪。他们还吃蛋糕、软饮料、糖果等，从中摄入大量的糖。结果许多人都成了胖子。而且有些人的牙齿也坏了。 在英国的一些地方，1/10的人到30岁时，牙齿就全掉光了！
