Low Fat Diet Won't Prevent Prostate
Eating a low fat diet does not appear to protect men
against prostate cancer,
How was the study conducted?
The researchers measured the risk of prostate cancer
in terms of rising levels of PSA, a protein produced
by the prostate gland. Spikes in PSA levels may signal
a man may have the beginnings of prostate cancer.
They followed a total of 1,350 men, with half receiving
intense counseling to opt for a low-fat diet that was
rich in fiber, fruit and vegetables. The researchers
then measured the men's PSA levels every year for 4
years, and noted when any study participant was diagnosed
with prostate cancer.
What conclusions were drawn from this study?
A similar number of men developed prostate cancer in
the two groups, which means that a man can't expect
a low fat diet will decrease his risk of prostate cancer.
