【推荐2】An analysis by Mount Sinai researchers of over eight years of dietary data from more than 400,000 people has found that the relationship between high consumption of fruits and vegetables and a reduced risk of cancer is not as strong as commonly thought. The study is published online April 6, 2010 in the Journal of the National Cancer Institute. It is widely believed that a diet rich in fruits and vegetables can reduce the risk of cancer. In 1990, the WHO recommended eating five servings of fruits and vegetables a day to prevent cancer and other diseases. However, although many studies have been conducted since then, none have been able to confirm an association between fruit and vegetable intake and cancer resistance.
Paolo Boffetta, MD, MPH, lead author of the study and Deputy Director of The Tisch Cancer Institute at Mount Sinai School of Medicine, and colleagues analyzed data from the EPIC study to evaluate relationships between cancer risk and intake of total fruit and vegetables combined.
The EPIC followers, which are ongoing and organized by professor Elio Riboli at Imperial College in London, included 142,605 men and 335,873 women surveyed between 1992 and 2000 from 10 Western European countries. Detailed information on their dietary habits and lifestyle differences was obtained. After 8.7 years of follow – up, more than 30,000 of the study's participants were diagnosed with cancer.
Dr. Boffetta and colleagues found a small but significant opposite relationship between high intake of fruits and vegetables and overall cancer risk. In this population, an increase of 200 grams a day of fruits and vegetables resulted in a reduction of about 3 percent of cancer risk. Vegetable consumption by itself also afforded a modest benefit but was restricted to women. Heavy drinkers who ate many fruits and vegetables had a somewhat reduced risk, but only for cancers caused by smoking and alcohol.
"The bottom line here is that, yes, we did find a protective effect of fruit and vegetable intake against cancer, but it is a smaller connection than previously thought," said Dr. Boffetta. "Any cancer protective effect of these foods is likely to be modest, at best.
"However, eating fruits and vegetables is beneficial for health in general and the results of this study do not justify changing current recommendations aiming at increasing intake of these foods," said Dr. Boffetta.

【推荐3】Section One
The city is an accumulation of human civilization. Just as the American social philosopher (哲学家) Lewis Mumford put it, it is a special system which, fine and compact, has been designed to preserve the fruits of human civilization. Many Western languages have developed their versions of the term “civilization” from the same Latin (拉丁语的) word “civitas”(meaning “city” ), and it is by no means a coincidence. The city has played a significant role in the perfection of order in human society.
Section Two
The emblem, showing the image of three people ― you, me, him/her holding hands together, symbolizes the big family of mankind. Inspired by the shape of the Chinese character “世” (meaning the world), the design conveys the organizers' wish to host an Expo which is of global scale and which showcases the various urban cultures of the world.
Section Three
Created from the inspiration of Chinese character “人”, the design roots deeply in Chinese culture. It tells the world the eternal core (永恒的核心) and theme of Shanghai World Expo will be always human. The mascot “Haibao” will become the messenger for the theme of World Expo 2010 Shanghai China “Better City, Better Life”.
The basic structure of the Chinese character “人” in which each stroke supports each other also shows the concept that the beautiful life should depends on mutual-help. If the human are willing to support one another, the harmony among human, nature, and society will be available. Such an urban life will be nice.   
Haibao’s confident smile is expressing his sincere greeting from China ― “World Expo 2010 Shanghai China welcomes you!”
