A study just published in the Journal of the National Cancer Institute warned that omega3 intakes can lead to an increased risk of prostate cancer.
But here is the key to the study...........it is ONLY the long chain omega3s (DHA and EPA) that are the concern! These are found in marine products such as salmon, etc. or in the oils produced from them.
The short chain form of omega3 found in chia is ALA and there is no evidence that there is a risk of increased prostate cancer from consuming ALA.
Bottom line is that this study confirms an earlier one published several years ago in Europe that consumption of long chain omega3s (EPA and DHA) can increase the risk of prostate cancer.
So any recommendations that are made to consume these forms of omega3 should also carry a warning of the potential risks as well.
