Health officials have encouraged people to eat fish, such as salmon, because they contain Omega-3 fatty acids, which are good for your heart’s health.
But researchers announced this week that men who have high levels of DHA – an Omega-3 fatty acid – in their blood have a greater risk for developing aggressive prostate cancer.
The study, published in the American Journal of Epidemiology, found that the risk was 2.5 times greater compared to men with the lowest DHA levels in the study.
Despite this, researchers said the healthy benefits of Omega-3s to your heart outweigh the risk related to prostate cancer.
“What this study shows is the complexity of nutrition and its impact on disease risk, and that we should study such associations rigorously rather than make assumptions,” said Theodore M. Brasky, lead researcher, in a news release.
The results of the study stunned researchers who expected to see additional benefits from taking Omega-3s.
“Our findings turn what we know, or rather what we think we know, about diet, inflammation and the development of prostate cancer on its head and shine a light on the complexity of studying the association between nutrition and the risk of various chronic diseases,” Brasky said.
The best advice of what to eat to stay healthy should come from your doctor or a Registered Dietitian. Although many medical professionals recommend taking Omega-3s, the government has not set a recommended daily allowance.
