Evidence of fish oil's benefit on health not conclusive

"Fish oil may be helpful in preventing deaths related to heart problems, but there is a lack of evidence that it provides a clear benefit in heart rhythm problems, according to a study. The authors of the study stressed the need for more funding for further studies on this neglected area of nutrient research. While heart attack survivors are recommended the consumption of oily fish at least two to four times a week, the authors of the current study insist that the evidence for the protective effect of fish oil supplements is based on one large trial from over 10 years ago. Posting their research paper on bmj.com, they underscored the fact that more recent trials had shown no beneficial effect of fish oil on patient outcomes" - medIndia
