The omega-6 fats contained in corn oil and other products may promote the growth of prostate cancer, according to a new study.
Omega-6 Spurs Cancer-Causing Enzymes
Working with human prostate cancer cells in tissue cultures, researchers found omega-6 fatty acids, added to the mix, spur the production of cPLA2, which then causes the production of the enzyme COX2. The introduction of COX2 stimulates the release of PGE2, a hormone-like molecule that promotes cell growth.
Simply put, if you're eating a diet that's high in omega-6 fats, you could be vulnerable not only to prostate cancer, but colorectal and some breast cancers as well.
Prostate Cancer Grows Along With Omega-6 Consumption
The incidence of prostate cancer over the past 60 years has risen as dietary ratios of omega-3 and 6 fats have changed. Back at the end of World War II, omega-3 and omega-6 ratios were lopsided (1:2) in favor of omega-3s. Now, that ratio is 25:1 on the omega-6 side.
The scientists who conducted the study were looking at possible new drugs to ward off prostate cancer based on the effect of flurbiprofen, a non-steroidal anti-inflammatory drug commonly prescribed for arthritis. Flurbiprofen blocks the production of cPLA2 and breaks the chain leading to cell growth.
