However, according to the authors, increasing the intake of EPA and DHA slightly reduced the “risk of coronary death and coronary events.” That said, the authors explain that these results may not translate to the real world.Ĭonsuming more ALA appears to have no influence on the risk of cardiovascular deaths, coronary deaths, or coronary events, but it may slightly reduce the risk of cardiovascular events and arrhythmia. In this context, “high certainty” means that the authors are relatively confident that the effect is not due to confounding variables or other factors. “Increasing EPA and DHA has little or no effect on deaths and cardiovascular events (high-certainty evidence) and probably makes little or no difference to cardiovascular death, stroke, or heart irregularities.” Having analyzed the data, the authors conclude:
#Reviews on freezzore black omega 3 trial
As with the cancer review, each study was a randomized control trial and ran for a minimum of 1 year. The other review, which appears in the Cochrane Database of Systematic Reviews, analyzed data from 86 trials, including information from 162,796 people. They also found that increasing the overall intake of PUFAs might slightly increase the risk of cancer diagnosis and cancer death. However, it may increase the risk of prostate cancer very slightly. Overall, the authors conclude that increasing omega-3 or ALA intake has little or no effect on the risk of developing cancer. They investigated whether or not omega-3, omega-6 (which is another essential fatty acid), or total PUFA intake might influence the risk of cancer incidence, breast cancer, or prostate cancer.Īll of the included studies involved adults without cancer and lasted for at least 1 year. In all, the scientists took data from 47 randomized control trials that included 108,194 participants. They have now published their findings in the British Journal of Cancer. To draw a clearer picture, the authors conducted a review of existing research. To date, the findings have been contradictory. Over the years, a number of studies have looked for links between omega-3 intake and cancer. The authors set out to examine some of these theories. There is a general assumption that boosting the intake of PUFAs boosts health, but as the authors of one of the new reviews write, these beliefs are “scientifically controversial.” Many people believe that omega-3, which is available over the counter as a supplement, can stave off a multitude of chronic conditions, such as cardiovascular disease and cancer.
docosahexaenoic acid (DHA), which also occurs in marine sourcesĪccording to the National Institutes of Health (NIH), because these fatty acids are present in a range of foods, omega-3 deficiency among healthy adults in the United States is “virtually nonexistent.”.
eicosapentaenoic acid (EPA), which commonly occurs in marine sources.Three types of omega-3 play a role in human health: As a result, consuming omega-3s is the only way to increase ALA levels in the body.Īmong other things, omega-3 fatty acids form part of cell membranes and play a role in the manufacture of certain hormones. However, the human body cannot manufacture it. One of these fatty acids, called alpha-linolenic acid (ALA), is an “essential fat.” Our bodies need ALA to function. Omega-3 fatty acids are polyunsaturated fatty acids (PUFAs), which occur widely in nature. Share on Pinterest Two reviews have investigated omega-3 and its potential health effects.
