Increased prostate cancer risk refuted by omega-3 fatty acids

Dietary supplements with omega-3 fatty acids protect heart health without increasing the risk of prostate cancer, as two recent studies show.

Current study results from the Intermountain Healthcare Heart Institute show that omega-3 fatty acids in dietary supplements protect heart health and at the same time do not increase the risk of prostate cancer. The results of two research on the subject were presented at this year's 2019 American Heart Association Scientific Sessions in Philadelphia.

Omega-3 fatty acids to protect against heart diseases?

Does it make sense to take supplements with omega-3 fatty acids to protect against heart disease, although there have been reports in the past that taking them could increase the risk of prostate cancer? The researchers at the Intermountain Healthcare Heart Institute have now announced that taking the popular nutritional supplement protects the heart without increasing the risk of prostate cancer.

Two new studies on the subject have been carried out

On November 17, 2019, the research group presented two new studies on omega-3 fatty acids at the American Heart Association Scientific Sessions 2019 in Philadelphia. One study looked at 87 people who were part of the Intermountain INSPIRE registry and had already developed prostate cancer. These patients were also tested for plasma levels of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), two common omega-3 fatty acids.

Higher omega-3 levels were not associated with prostate cancer

When compared to a control group of 149 men, the researchers found that higher omega-3 levels were not associated with an increased risk of prostate cancer. This disproves the results of a study from 2013, which suggested a possible connection between higher omega-3 plasma levels and the development of prostate cancer.

No evidence of a connection was found

"When I recommend Omega-3 to my patients to protect their hearts, I want to make sure I don't put them at risk for prostate cancer," study author Viet T. Le of the Intermountain Healthcare Heart Institute said in a press release. "Our study found no evidence of a connection," added the doctor.

The second study examined blood flow in the heart

In the second study presented, the researchers examined 894 patients who underwent so-called coronary angiography. This test shows how our blood flows through the arteries in the heart. These patients had no history of heart attacks or coronary artery disease, but after their first angiogram, about 40 percent had a serious illness and about 10 percent had a so-called three-vessel disease, Le said.

Plasma levels of the omega-3 metabolites were measured

The researchers also measured plasma levels of omega-3 metabolites, including DHA and EPA. Patients were then medically monitored to determine who later had a heart attack, stroke, or heart failure. Of course, deaths that occurred were also taken into account.

Does Omega-3 Really Help Protect Our Heart?

Patients who had a higher rate of omega-3 metabolites were less at risk of the above effects regardless of whether or not they had a severe illness with their angiogram. The results of the study are important because it looked at how omega-3 helps patients who already have heart disease.

Omega-3 improves survival

While an apparent link between higher plasma omega-3 levels and the results of severe heart disease after the initial angiogram might raise concerns that omega-3 fatty acids are not beneficial, the researchers found that there is a link between higher omega -3 values ​​and survival after ingestion there.

Omega-3 does not increase the risk of prostate cancer

In summary, one could say that higher omega-3 levels are unlikely to be associated with an increased risk of prostate cancer, while at the same time the intake appears to protect against death from heart disease. (as)
