Researchers were surprised to discover that a high level of Omega 3 fatty acids, promoted as a benefit for heart, is directly correlated with the aggressive risk of prostate cancer. Conversely, a low level of Omega 3 is associated with a lower risk of prostate cancer.
The Medical News Today site informs that this is the largest study ever conducted to identify the links between fatty acids and risk of prostate cancer.
Theodore M. Brasky, who led the study conducted at the Cancer Research Center Fred Hutchinson from Seattle, Washington, says that the research team was extremely surprised by these results. The research was based on data analysis of 3,400 men.
Good for heart, bad for the prostate
According to the tests results, men with high blood levels of DHA (decosahexaenoic acid), which is an Omega-3 fatty acid found in fatty fish such as mackerel or salmon, have a 2.5 times higher risk of aggressive cancer prostate, compared with men whose blood levels of DHA is low.
Another surprising finding of the study is that men with high levels of trans fatty acids (existing in processed foods), which promotes heart disease, have a 50% lower risk of prostate cancer.
Do not reduce fish consumption
The reason for getting these results is still a mystery to researchers. Despite the data, they say that nutritionists should not stop recommending patients to eat fish – which is indicated to prevent heart disease. Also they should keep recommending food supplements where necessary. To see exactly how Omega-3 influences the prostate cancer, and to start recommending any reduction in the consumption of foods with Omega 3 fatty acids, further research is needed.
