Abstract:

 

The epidemiologic literature on the relationship between vegetable

and fruit consumption and human cancer at a variety of sites is reviewed

systematically. A total of 13 ecologic studies, nine cohort studies, and 115

case-control studies are included. Cancer of all sites, cancers of lung, breast,

colon, rectum, esophagus, larynx, oral cavity and pharynx, stomach, pancreas,

prostate, bladder, ovary, endometrium, cervix, and thyroid, as well as

mesothelioma and gestational trophoblastic disease, are considered. Relevant

data from clinical trials, animal, and in

vitro studies are included.

 

It is concluded that consumption of higher levels of vegetables and fruit is

associated consistently, although not universally, with a reduced risk of cancer

at most sites. The association is most marked for epithelial

cancers-particularly those of the alimentary and respiratory tracts.

 

The association exists for a wide variety of vegetables and fruit with some

suggestion that raw forms are associated most consistently with lower risk.

Possible mechanisms by which vegetable and fruit intake might alter risk of

cancer will be

considered in Part II of this review.
