A Healthy Diet
A healthy diet is very important for people. It contains some fat, some fibre, a little salt and so on. The Chinese diet is considered to be the healthies [fm1,-] in the world. It contains a lot of fruit and vegetables. It is rich in fibre and low in sugar and fat. As a result, a lot of Chinese have healthy white teeth. So I am very happy to be Chinses [fm1,-]. People in west eat too much fat and sugar. They like to eat butter, cream, chocolate, sweet and so on, which contain a lot of sugar. As a result, they put on weight easily. Many of them become very fat and some have bad teeth. The worset [fm1,-] thing is that many westerners die in an early age from the heart illness. So I thought [vp6,s-] [vp1,2-2] eat more fruit and vegetables, not to ear [wd3,1-2] too much sugar and fat is a real healthy diet. [sn8,s]

What is a healthy diet?

Besides, many of them have weight problems. However, a new hamburgar [fm1,-] restaurant in Beijing was quite popular. A doctor advised people not to have hamburgar [fm1,-] for it's not a good diet. Neither is the Coca Cola. So we should think we're lucky to have the healthy Chinese diet.
