A number of lab studies have shown that eating a low-fat diet complete with omega-3 fatty acids can potentially slow metastatic prostate cancer. A team of researchers at the University of California, Los Angeles recently conducted a study on human prostate tissue that adds support to previous laboratory trials.
In order to reach their conclusions, the researchers put study volunteers on a low-fat diet supplemented with fish oil during the four to six weeks leading up to their prostate removal surgery.
After the gland was removed, scientists examined the tissue and determined that participants on the special diet had fewer rapidly dividing cancerous cells when compared to the control group. Authors of the study said their findings suggest that consuming healthy foods may reduce an individual's chances of cancer progression.
"The lower the rate of proliferation, the lesser the chances that the cancer will spread outside the prostate, where it is much harder to treat," said first author William Aronson, M.D.
The researchers ensured consistency in their subjects' diets by serving them specially prepared meals and instructing them to keep a food diary.
