More and more Chinese people care for their own health. I come from England. I came to China five years ago. I began to learn cooking Chinese food from my father. When I was fifteen, I began to help my mother in the kitchen. My father is a very famous cook in Beijing. So he taught me many things about cooking. In the past three years, I never stopped learning cooking. When I saw a book called The disease eating out can be gone back again by eating (<<>> ), I began studying the book. .The writer of the book is Zhang Wuben. He said he was a famous nutritionist  and well-known traditional Chinese doctor. He asked the people to eat eggplant  and gram  . In China, Zhang Wuben's book has been popular in the past few years. My father was invited to talk about the book in May, 2010. A large number of Chinese people believe they should eat eggplant and gram to be healthy. I have visited a lot of Chinese restaurants in Beijing and studied hundreds of restaurant menus.  I talked to lots of doctors about eating and nutrition  . They thought that Zhang Wuben's words _ the science. He told a lie. The fact is that it's important for us to eat a balanced diet and not just to eat eggplant and gram. What do you think of Zhang Wuben's book?
It is a book about health. Now it is the most popular science writing. It can keep a balance of yin and yang. It is a trashy   book. It's a book on medicine.
