摘要: There is a great variation in cancer incidence with diet, as has been recently reviewed (1,2). Epidemiological data suggest that environmental, specifically nutritional, factors play major role the etiology of at many different sites (1–3). are now several epidemiologic studies which components vegetables might beneficial lowering (some examples such given references 1-4). Although compounds anticarcinogenic potential present vegetables, it possible protease inhibitors contribute to low rates observed certain human populations high levels diet. For example, Japanese and Seventh-Day adventists could be due dietary inhibitors; estimated individuals these ingest, on average, more than 330 mg per day (3). are, however, other hypotheses have presented explain populations. So variables diet effect any specific agent cannot distinguished studies; distinguish effects agents laboratory experiments. In this report, our own will summarized discussed. can give much information about chemopreventive agents, ultimately intervention must performed determine whether candidate truly capable preventing The current evidence do (6 7).
