A vegetarian(素食者)diet may help to protect people against cancer, a UK study suggests. Analysis of data from 52,700 man and women shows that those who did not eat meat had significantly fewer cancers than those who did.
Published in American Journal of Clinical Nutrition, the findings were worth looking into .Although it is widely recommended that people eat some fruits and vegetables every day to reduce their risk of cancer and other diseases, there is very little evidence showing that a vegetarian diet can surely reduce cancers .
But surprisingly, the researchers also found a higher rate of colorectal(直肠的)cancer – a disease connected with eating red meat – among the vegetarians.
Study leader Professor Tim Key, a researcher at the University of Oxford, said no previous study had looked at the diet in this way and that there had been a lot of confusion about the issue.
“It’s interesting – it suggests there might be some reduction in cancers in vegetarians, but we need to look carefully at that”, said the professor.
More work is needed to show the connections between diet and cancer but such studies are very hard to do. Dr Joanne Lunn, a senior nutrition scientist at the British Nutrition Foundation, said the findings highlighted the fact that cancer is a complex disease and many different lifestyle factors play a part in determining a person’s risk.

A. Reasons for getting cancers.

解析
All right! Enough cookies,cola, and chips! It seems that junk food is all that the children want to eat these days.Television controls their tastes.The kids see well-known personalities eating potato chips, candy and other processed food, and they want to be like their heroes.How do they do it?They eat the same food. I wish there were more characters like old Popeye(大力水手), the sailor, who ate spinach(菠菜) and not French fries.
Now I don't expect my children to eat healthy food because I like brown rice, beans, and fresh vegetables. I'm glad to cook traditional meals of meat and potatoes for them. I really can't be too upset with the kids because most adults aren't careful about what they eat. The other night, my wife and I went to a party where there was plenty to drink but very little for us to eat. They served hot dogs and hamburgers. I can't eat hot dogs, with all those preservatives(防腐剂), and hamburgers are filled with chemicals so that they look better. Besides the meat, they had sugar-filled cookies and cake, and of course, chips. I don't want the world to change because of me, but I think people should realize that there are alternatives(选择) to eating meat. They always tell me that I probably don't get my essential(必要的) proteins. I feel better than ever and I'm sure that it's because I'm a vegetarian(素食主义者). I would really like to see more television advertisements which show the benefits of good, healthy, natural food.
