Diet and Upper Gastrointestinal Malignancies

摘要: Diet is believed to modulate cancer risk and this relationship has been widely studied in the gastrointestinal tract. Observational epidemiologic studies have provided most of evidence about effects diet on because clinical trials determine nutritional exposures are often impossible, impractical, or unaffordable. Although a few foods nutrients thought protect against specific types cancer, it seems clear that strength even direction dietary associations (increasing decreasing risk) organ-site− histology-specific, along some hypotheses supported by substantial body observational data (drinking hot mate [an infusion herb Ilex Paraguarensis ] contributes esophageal cancer), there not much support others. We discuss highly touted draw interim conclusions what known could be done improve level evidence. The complex nature its can productively investigated with disease-specific studies. However, public health recommendations for normal-risk individuals regarding should probably emphasize importance eating overall rather than reduce cancers.
