Inuit Had Genetic Adaptations To Fatty Acids: Study

The Omega-3 fatty acids usually considered as the protector from heart attack or stroke and the believe is also based on the research of Danish researchers in the 1970s on Inuit people spread across Arctic and their diet was mostly sea fish including seals and whales.

The Inuit people had no choice as on the tundra region there were not many wild plants to forage and also very less amount of berries sometimes. The sea foods were full of fatty acids and the Inuit people didn’t have a lot of heart attacks.

However, there has been lately a different theory to it. One recent study suggest omega-3 fatty acids does not offer protection to heart attacks or stroke even though 10 percent of the Americans take fish oil supplements regularly.

The study is published in the Science journal and it writes the Inuit ancestors evolved unique genetic adaptations for the fatty acids. Also, the gene variants among them had great effects on their bodies. Their height got shortened and their weight was reduced too.

The new study raises questions on the omega-3 fatty acids whether it really protects the heart despite doctors and other health care people have advised its intake to keep good health.

Dr Rasmus Nielsen, a geneticist at the University of California, Berkeley, said same diet may offer different effects on different people.

He said the difference is also seen with milk. Some people digest it throughout their lives.

Dr Nielsen is the author of the new study.
