Diet Reduces Prostate Cancer

Diet Reduces Prostate Cancer | Cancer - Advances, Knowledge, Integrative & Holistic Treatments | Scoop.it
Men with prostate cancer who followed a low-fat diet and had a regular intake of fish oil supplements showed changes in cancer tissue that could indicate reduced cancer aggression.
Graham Player Ph.D.'s insight:

Research published in the journal Cancer Prevention Research reveals that fish oil supplements and a low-fat diet reduces prostate cancer aggression.

It is known that low-fat diet and omega-3 affects cell biology. Omega-3 fatty acids are commonly found in plant and marine life oils. Omega-3 is known to reduce inflammation and has been linked to many health benefits, including the prevention of oral and skin cancers. The typical western diet includes high levels of omega-6 fatty acids but low levels of omega-3.

There are many circumstances in life that can feel out of our control.  Lifestyle choices, what we choose every day to put into our bodies, how we choose to keep our bodies active, ways we learn to reduce and eliminate stress...we have a say in all of these.  Start with one simple change.  For just a couple of weeks, eliminate sugar, choose two weeks without fried foods, get moving - choose some healthy lifestyle you aren't currently implementing...then re-evaluate.  How do you feel?  What do you notice?  More mental clarity?  More energy?  Change what you can with actions you take - that is something you can do for yourself, your family and your community.

 

Need support to make those changes?  Too stressed to even fathom adding in exercise or giving up that soda?  Find out how coaching can support your vision for more and better health.  Email me for more information tleighn@iPECcoaching.com

Fish Oil (Omega-3) and Prostate Cancer

Further information on the recent report that implicates omega-3 fish oil with prostate cancer.

 

Graham Player Ph.D.'s insight:

I looked further into the recent study published in the Journal of the National Cancer Institute that asserts “increased prostate cancer risk among men with high blood concentrations of LCω-3PUFA. The consistency of these findings suggests that these fatty acids are involved in prostate tumorigenesis.”

According to the popular media it was typically reported as follows – “study found that men with high levels of omega-3 in their blood were at 43 per cent greater risk of prostate cancer than those with low concentrations, while less common aggressive “high-grade” tumours were 71 per cent more likely than in those not taking supplements."

So I went searching for some independent expert opinions, which led me to listen to an interview with Dr. Anthony V. D’Amico. He is a professor of Radiation Oncology at Harvard Medical School and is the chief of Genitourinary Radiation Oncology at the Brigham and Women's Hospital and Dana-Farber Cancer Institute. He has gained international notoriety for his work in detection, staging, and treatment of prostate cancer with over 140 peer-reviewed publications, and has co-edited four textbooks in Urologic Oncology. Therefore his credentials would certainly make him an authority on the subject of prostate cancer.

When asked to comment on the controversial study, I have paraphrased many of his comments as follows.

The scientific strength of the study is weak, at best, and the study cannot make the conclusion that it is trying to. These types of association studies cannot prove cause and effect, and are simply associations.

The way to strengthen an association study of this type is by making adjustments in the study for all the things you know can cause prostate cancer. This wasn’t done properly in this particular study.

They did make adjustments for things like family history of prostate cancer and diabetes. However they left out some very important risk factors for prostate cancer – such as ethnic race, age, PSA levels, physical exam results, and BMI or weight. For example overweight has been shown to be associated with more aggressive prostate cancer.

So we are left with an association that at best is very weak, and further weakened by the fact that no account was made for the known predictors of prostate cancer.

Further, it is not known whether the men in the study with prostate cancer started taking fish oil before they had the cancer or afterwards, and whether they were taking supplements or eating fish and for how long. The source of the fish oil is also not known.
