Diets high in fish do not promote heart heath and may increase risk of heart disease, according to a study in the Canadian Journal of Cardiology.
Researchers conducted a review of ten different studies analyzing the diets and health of Eskimos and Inuits in Greenland and North America. They found that Eskimos in Greenland have similar rates of heart disease, an overall mortality rate twice as high, and a life expectancy 10 years shorter, compared with non-Eskimos. Inuits in North America have similar if not higher rates of heart disease, compared with non-native populations.
The authors conclude that an "Eskimo diet" has been misconstrued as heart healthy in the past and that such a high-fat diet is better labeled dangerous.
