Comprehensive
lifestyle changes including a better diet and more exercise can lead not only
to a better physique, but also to swift and dramatic changes at the genetic
level, U.S.
researchers said on Monday. In a small study, the researchers tracked 30 men
with low-risk prostate cancer(前列腺癌)who decided against
conventional medical treatment such as surgery and radiation or hormone
therapy.
The
men underwent three months of major lifestyle changes, including eating a diet
rich in fruits, vegetables, whole grains, legumes and soy products, moderate
exercise such as walking for half an hour a day, and an hour of daily stress
management methods such as meditation(冥想). As expected, they lost
weight, lowered their blood pressure and saw other health improvements. But the
researchers found more profound changes when they compared prostate biopsies
taken before and after the lifestyle changes. After the three months, the men
had changes in activity in about 500 genes -- including 48 that were turned on
and 453 genes that were turned off. The activity of disease-preventing genes
increased while a number of disease-promoting genes, including those involved
in prostate cancer and breast cancer, shut down, according to the study
published in the journal Proceedings of the National Academy of Sciences.
The
research was led by Dr. Dean Ornish, head of the Preventive Medicine Research
Institute in Sausalito, California, and a well-known author
advocating lifestyle changes to improve health. "It's an exciting finding
because so often people say, 'Oh, it's all in my genes, what can I do?' Well,
it turns out you may be able to do a lot," Ornish, who is also connected
with the University
of California, San
Francisco, said in a telephone interview. "'In just three months, I can
change hundreds of my genes simply by changing what I eat and how I live'.
That's pretty exciting," Ornish said. "The implications of our study
are not limited to men with prostate cancer."
