西红柿没有抗癌的作用

Tomatoes do not help prevent cancer

    The U.S. Food and Drug Administration (FDA) said that tomatoes do not really help prevent cancer after its review of all known lycopene (番茄红素) studies.
“The review found no evidence that tomatoes could reduce the risk of cancer. It said there was very limited evidence for relationships between tomato consumption and reduced risk of cancers.”
“Very limited and preliminary (初步的) scientific research suggested that drinking one-half to one cup of tomato sauce a week might reduce the risk of prostate (前列腺) cancer. The FDA said that there was little scientific evidence supporting this result.”
    The review, which appears in one issue of the Journal of the National Cancer Institute (《美国国家肿瘤研究所杂志》), refuted lots of studies which had pointed to a link between eating lycopene, which gives tomatoes their red color, and a reduced risk of certain cancers.
   However, Edward Giovannucci of the Harvard School of Public Health said the field of research remained promising, even if it was too early to point to a definitive relationship between consuming lycopene and lowering the risk of some cancers.
   The FDA undertook the review of 145 studies after a coalition (联盟) of tomato-growers and tomato-product processors asked permission to include label information about the anti-cancer benefits of tomatoes.
