What’s
good for the heart may not be so healthy for other organs, says the
latest study that links omega-3 fatty acids to an elevated risk of
prostate cancer.
It’s
not just an apple a day that keeps the doctor away anymore —
recently, fish oils found in species like salmon, trout and tuna have
been associated with a lower risk of heart disease and
even Alzheimer’s.
In fact, the most recent revisions to the Dietary Guidelines for
Americans in 2010 recommended consumers substitute high-fat protein
sources with more seafood, including fatty fish.
Not
surprisingly, fish oil has
since skyrocketed to be the most popular supplement in
the United States. A new study in the Journal
of the National Cancer Institute, however,
shows that these fish fats may not be improving everyone’s health —
in the trial, those with high concentrations of marine-derived
omega-3s in their blood showed a 43% higher risk of developing
prostate cancer than those with the lowest levels.
It’s
not that omega-3s are harmful, but that the fatty acids may have more
complex effects on the body than previously thought. “We have this
tendency to talk about good foods and bad foods, good nutrients and
bad nutrients,” Dr. Theodore Brasky, a research assistant professor
at The Ohio State University Comprehensive Cancer Center and the
study’s head author. The nutrients commonly found in fish fight
potentially damaging inflammation, but they may also increase
oxidative damage to the DNA in cells, similar to the effects of
stress, that can create fertile ground for cancers to grow.
Scientists no go kill us. Today eat Salmon, tomorrow No. Just eat healthy abeg.
