Omega-3 fatty acid anti-cancer effect is exposed Expert: basically no use

A new study from the University of East Anglia in the UK has shown that omega-3 fatty acids do not protect against cancer, according tomedia reports. In recent years, increasing the intake of omega-3 fatty acids has been widely promoted worldwide, as it is widely believed to prevent or even reverse diseases such as cancer, heart disease and stroke.

But new research published in the British Journal of Cancer suggests that omega-3 fatty acid supplements may slightly reduce mortality and morbidity from coronary heart disease, but also slightly increase the risk of prostate cancer, with little beneficial and harmful effects.

The team looked at 47 trials involving adults who were not at increased risk of cancer or had been diagnosed with cancer, and 86 trials with evidence of cardiovascular events or deaths.

More than 100,000 participants were randomly divided into two groups, one taking more long-chain omega-3 fatty acids (fish oil) and the other maintaining their usual intake for at least a year. The researchers analyzed the number of people who died from cancer, heart attack or stroke and/or any disease.

It was found that if 1,000 people took the omega-3 supplement for about four years, three would avoid death from heart disease, six would avoid coronary artery events (such as heart attacks) and three would develop prostate cancer.

The researchers say much of the evidence for omega-3 fatty acids comes from experiments with fish oil supplements, so the health effects of oily fish rich in long-chain omega-3 sitts are unclear. And oily fish as part of a balanced diet, is a very nutritious food, rich in a variety of proteins and nutrients.

But the large amount of information we have come up with in our study suggests that the overall impact on our health is small if we take omega-3 supplements for several years, the risk of heart disease may be slightly reduced and the risk of certain cancers slightly increased, but this risk is offset by the protective effects of cardiovascular disease, so the overall impact on our health is small.
