"A popular study from the 1970s that helps sell millions of dollars' worth of fish oil supplements worldwide is deeply flawed, according to a new study being published in the Canadian Journal of Cardiology. The original study, by Danish physicians H.O. Bang and D.J. Dyerburg, claimed Inuit in Greenland had low rates of heart disease because of their diet, which is rich in fish oil and omega-3 fatty acids from eating fish and blubber from whales and seals."

Though the information is this video is very helpful, I've often found when looking at sources for studies on PubMed online (and other sources for research) that the formatting of the study, or the diction makes it completely incomprehensible. A group should be formed that makes important or often cited studies reformatted to be understandable by laymen and laywomen, so that people can truly be informed citizens.
