A Low-Fat Diet to Decrease Spread of Prostate Cancer
A new, small study has indicated that changing diet and
lifestyle habits could play a role in the spread of early-stage prostate cancer.
Participants in the study all had early-stage, non-aggressive prostate cancer
that they had decided not to treat, which is an approach called “watchful
waiting.” Half of the participants adopted a vegetarian diet, limited fat to
only 10 percent of their total calories, got regular exercise and practiced
stress management techniques, such as yoga. The other half didn’t make any
dietary or lifestyle changes.
After one year, tests revealed that the men who had made
the lifestyle changes had a 4 percent decrease in PSA—a marker for prostate
cancer—in their blood. Those who hadn’t made changes experienced a 6 percent
increase in PSA.
It’s important to point out that the study was small, so
further research is necessary to prove conclusively that the changes the men
made would be as effective in a larger population sample.
