According to a study conducted by Dr. William Aronson, a professor in the department of urology at the David Geffen School of Medicine at UCLA in mice it was found that a proper balance in th ratio of omega-3 and omega-6 fatty acids reduced the prostate cancer growth rates.
The study results were published in the journal Clinical Cancer Research. He said that Americans had an increased amount of omega-6 fatty acids containing diet such as corn, safflower oils and red meats. On the other hand omega-3 fatty acids are found in cold-water fish like salmon, tuna and sardines. The researcher said that by eating a healthy ratio of these two types of fatty acids could make a difference in reducing prostate cancer growth. But further studies are essential to prove that this works in case of humans.
Statistics show that the incidence of the disease is increasing with a rise of 1.7 % over 15 years. Prostate specific antigen (PSA) is a protein that is used as a marker for the disease - higher levels are associated with a higher risk of prostate cancer. According to the study it was found that eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) lead to the development of more anti inflammatory prostaglandins which reduce the growth of the prostate tumor.
