Empty joy! Omega-3 fatty acids don't prevent cancer!

March 11, 2020 / / -- omega 3 fatty acids do not prevent cancer, according to a new study from the University of East Anglia.
omega 3 fatty acids are widely used worldwide because they are widely believed to prevent or even reverse diseases such as cancer, heart disease and stroke.
but two recently published systematic reviews found that supplementation with omega-3 fatty acids may slightly reduce coronary heart disease mortality and morbidity, but slightly increase the risk of prostate cancer.
both beneficial and harmful effects are small.
photo source: If 1,000 people take the omega 3 supplement for about four years, three people can avoid dying from heart disease, six people can avoid coronary artery disease (such as a heart attack), and three people will develop prostate cancer.
omega 3 fatty acids are a type of fat.
small amounts are important for good health, and the foods we eat, including nuts, seeds and fatty salmon, contain the substance.
omega 3 fatty acids as over-the-counter supplements are also ready and widely used.
team looked at 47 studies involving adults without cancer, people with an increased risk of cancer, or people diagnosed with cancer, and 86 trials with evidence of cardiovascular events or death.
more than 100,000 participants were randomly assigned to eat more long-chain omega-3 fatty acids (fish oil) for at least a year, or to maintain their usual intake.
they studied the number of deaths, new diagnoses of cancer, heart disease or stroke, and/or deaths from any disease.
lead author Dr Lee Hooper, from the Norwich School of Medicine at the University of East Anglia, said: "Our previous research has shown that long-chain omega 3 supplements, including fish oil, do not prevent anxiety, depression, stroke, diabetes or death.
", these large-scale systematic review studies include long-term information from thousands of people.
a lot of information that suggests that if we take the omega 3 supplement for several years in a row, our risk of heart disease may be slightly reduced, but at the same time, the risk of certain cancers may be slightly increased.
the overall impact on our health is minimal.
evidence for omega 3 fatty acids comes mostly from trials of fish oil supplements, so the health effects of fish oil rich in long chains of omega-3 fatty acids are unclear.
oily fish is a very nutritious food, part of a balanced diet, rich in protein and energy, and important micronutrients such as selenium, iodine, vitamin D and calcium -- it's not just a source of omega 3 fatty acids.
: "But we found no significant value in taking omega-3 fatty acid supplements to prevent or treat cancer.
fact, we found that they may slightly increase the risk of cancer, especially prostate cancer.
, however, this risk is offset by the same small protective effects of cardiovascular disease.
given the environmental impact of industrial fishing and its impact on fish stocks and marine plastic pollution, it seems unhelpful to continue to take fish oil fillers, as it brings little benefit.
