Recent headlines and news reports have conveyed somewhat startling recommendations that men
should stop eating fish and taking fish oil supplements as a result of a study
published in the Journal of the National Cancer Institute that was reported to
show that fish consumption and/or fish oil supplement usage was “strongly
associated” with an increased risk of the most aggressive form of prostate
cancer.
Informed consumers need to look beyond
attention-grabbing headlines to find that the data in this study actually does not support that assertion at all.
The study looked at blood levels of omega-3's, which measures
recent consumption of omega-3's and are not a measure of long-term consumption
of omega-3's.
This measurement does not
differentiate different sources of omega-3's-so could be measuring avocado,
olive oil and fish consumption.
There was no tracking
of usage of fish oil supplements or even fish consumption by study
participants. It must also be noted that the results of this study are
completely contrary to the large body of scientific
and epidemiological data that supports the positive effects of fish oil
supplements and/or fish consumption on cardiovascular health, peri-natal
health, inflammation, cognitive function, and many types of cancer.
Additionally, there are both randomized clinical trials as well as
population data that validate the protective
effects of omega-3 supplementation on reduction of risk of prostate cancer
as well as reduced risk of prostate cancer metastasis (spread).
The
American Heart Association, the World Health Organization, the U.S. Institute
of Medicine’s Food and Nutrition Board and a multitude of health experts and physicians
(including the Shaklee scientific team) continue to support
and recommend omega-3 and fish oil consumption for the variety of potential
health benefits associated with this choice.
It would seem that this study does not give anyone reason to change
those recommendations.
