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. (abstract [onlinecjc.ca])
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.
Dr. George Fodor, the new study's lead researcher, says the old study upon some public health records and on hearsay. The problem with those? The chief medical officer's annual records were likely deficient because the inaccessible, rural nature of Greenland made it difficult to keep accurate records, and also because many people didn't have access to doctors.
The new 2014 study has found that Inuit do have similar rates of heart disease compared to non-Inuit populations, and that death rates due to stroke are "very high."
The study also shows that the Greenland Inuit overall mortality is twice as high as non-Inuit populations.
Is this a similar case as for cholesterol, about which some say [biohackme.net] that blaming it for hearth attack is like blaming firemen at the site for causing fires?
