Franco, thanks for posting that link. I've not come across Dr. Geo before, but IMHO EVERYONE should go to that link and check it out. A few 'notables' that I took away from it:
An important clinical study published by a group at the Harvard School of Public Health examined the link between dietary fish consumption and the risk of metastatic prostate cancer. This paper reported results from the Health Professionals Follow-up Study that involved 47,882 men over twelve years. During the twelve years, 2,483 cases of prostate cancer were identified. Of these, 617 were advanced and 278 were metastatic. Eating fish more than three times a week reduced the risk of prostate cancer but had an even greater impact on the risk of metastatic prostate cancer. For each additional 500 mg of marine fat consumed, the risk of metastatic disease decreased by 24%! (Augustsson, et al. 2003).
Most men will develop prostate cancer within time regardless of what they eat or don’t eat. If you live long enough, you’ll get it. The deadly kind is what we are trying to avoid.
The 71% aggressive prostate cancer associated with Omega 3 fatty acid consumption sounds dubious.
The fish oils from fish or supplements in the study did not control for the quality of fish or fish oil. Some fish (and fish oil supplements) can contain environmental chemicals that can contribute to prostate cancer such as PCB (Ritche et al. 2005). Also, fish oils can oxidize easily if not careful which may make them more damaging. This was not accounted for in this study.
I do recommend for readers to be properly monitored by a nutritionally oriented physician when making dietary choices. There are individual nuances where, indeed, a nutrient can potentially make health matters worse.
Lastly, (whew!) another shortcoming of both Brasky studies is that we do not know the diet of the studied subjects. The consumption of fish or fish oil supplements with crappy food does not make the crappy food less crappy. Another words, a poor diet with fish or fish oils will not protect men from prostate cancer.
Not trying to beat a dead horse here, but for ME - "One must be very careful with making decisions based on the latest news bytes and headlines. We, as a society, have a tendency to make decisions based on the last study or news advertised, rather than the combination of studies published on a specific topic.
The last study is not necessarily the best study."
