On July 10th, the headline read, “Men Might Want
to Shun Fish oils, Study Shows.” This new study from the Fred Hutchinson Cancer
Research Center supposedly shows a link between increased EPA/DHA levels in the
blood and prostate cancer risk. Given all the positive health effects linked to
fish oil intake, this study definitely seems out of step with previously shown
benefits.
As I have said before, always try to find out more about who
did the study, how it was performed and if it has been repeated by others. I am
no expert in these activities, but I have found a great article written by an
expert, Dr. Michael Murray. He is a leading authority on natural medicine, and
has written over 30 books on health and nutrition. Much of the following
information is attributed to this article: “How a SELECTed Bad Study Became Big
News,” written on July 12, 2013, and published online at GreenMedinfo.com.
Dr. Murray says the pedigree of this study is impressive. It
was published in the Journal of the National Cancer Institute and was conducted
by researchers at the Fred Hutchinson Cancer Center in Seattle, WA. Yet, the
data used is from the much maligned Selenium and Vitamin # Cancer Prevention
Trial, or SELECT. That is the problem.
