I would be delighted to announce that eating more vegetables and fruits
would prevent breast cancer but look at this excerpt from the study
above:

"Inverse associations between intakes of fruits and vegetables and
breast cancer risk have been reported in a notably large number of
case-control studies [90]. However, in the pooled analysis of eight
large prospective studies (7377 cases among 351,825 women), only weak
and nonsignificant associations were seen with increasing consumption of
fruit and vegetables [91]. Comparing highest with lowest quartiles, RRs
were 0.93 (95% CI = 0.86-1.00) for total fruits, 0.96 (0.89-1.04) for
total vegetables, and 0.93 (0.86-1.00) for total fruits plus vegetables.
A thorough search among specific fruits and vegetables and botanical
groups did not reveal any significant associations.

Associations between red meat consumption and risk for breast cancer
have been reported sporadically [92]. However, as previously mentioned,
breast cancer rates among UK nuns who ate little to no meat were similar
to rates among single women from the general population [6]. In the
pooled analysis of large cohort studies (7379 cases) [93], no
association was seen with consumption of red meat, white meat, or dairy
products. In an analysis that retrospectively assessed degree of cooking
[94], consumption of well-done red meat was associated with breast
cancer incidence. This will require evaluation in prospective analyses."

No very encouraging. However, I do admit that when it comes to other
cancers, the situation looks different.
