Cauliflower May Make Aggressive Prostate Cancer Less Likely
Men who often eat broccoli and
cauliflower may be less likely to develop aggressive prostate cancer
than men who skimp on those vegetables.
That news appears in the Journal
of the National Cancer Institute.
The finding comes from a study of
more than 29,000 U.S. men aged 55-74 who were followed for an average of four
When the study started, the men

and soy could cut cancer risk
Compounds found in broccoli and soy may help protect
against certain cancers that affect over two million new people every year,
according to a cell culture study.
Indole-3-carbinol (I3C), a phytochemical found naturally in
cruciferous vegetables like broccoli
and cauliflower, and genistein,
a soy isoflavone, were shown to have potential
prevention activity against hormone-responsive tumours,
such as breast, ovarian and prostate cancer.
Epidemiological and animal studies
have shown that diets high in such vegetables resulted in less instances of
certain cancers, while a trial supplementing the diet with I3C reported the prevention of oestrogen-dependent tumours. This
led researchers to test the effect of I3C,
and genistein, on human breast and prostate cancer
cell cultures. (Read
