But a recently published study states that taking these supplements does not reduce the risk of heart attacks, strokes, or coronary heart disease "There was no evidence to support this belief.It has been established in recent decades, but it was based on studies that have not been conducted with sufficient rigor, "said Lee Hooper, who participated in the research.

Cold Origins
It all started with a study published in June 1971 in the scientific journal The Lancet.
In the 70s, the habits of a group of 130 Eskimos vivan t on the west coast of Greenland were badyzed by Danish researchers.
They underwent several tests and found that their cholesterol and triglyceride levels were low, despite regular consumption of high-fat meat.
The Eskimos Regime is very special
Because of the extreme climate of the Arctic, they can not grow fruits, vegetables or grains, they eat what they hunt, mainly in the sea: fish, seals and whales. [1 9659003] So Danish scientists concluded that it was the Eskimo diet that explained the low incidence of heart attacks and the absence of diabetes mellitus in this population.
This is how the recommendation was born that fish consumption was good for preventing coronary heart disease.
And from that moment began the popularity of fish oil pills, which contains large amounts of omega 3.
