It has already been three decades since Richard Nixon declared fight against cancer, during which many specialists and scholars spent a large amount of money trying to seek various ways to crack this hard nut. Yet today the death rate of cancer is nearly as high as it was in the 1970s. American women's death rate of breast cancer is five to thirty times as high as that of women in many other countries of the world. In Thailand, only two to five out of every 100,000 women die of breast cancer, whereas in the United States, 30 to 40 meet that fate. Among all the reasons, no one denies that diet is a large part of the reason. Some scientists hold, “It's our greatest exposure to the environment because humans put two to three pounds of food into their bodies every day.” Hence people should place a great emphasis on good eating habits. Though the correct eating habit can't eliminate cancer in the world, it can help reduce the risk of cancer.
