28. Fish like the Eskimos
The Eskimo populations of Alaska and Greenland eat a high-fat diet, but have low levels of heart disease. So what’s the answer to this conundrum? It’s in the fish.
The deepwater fish eaten as a staple by these populations are rich in omega-3 fatty acids, and researchers discovered that this particular type of fatty acid protects the heart.
There is now good scientific evidence that eating oily fish reduces the risk of death from heart disease because they’re a good source of omega-3 polyunsaturated fatty acids. White fish also contain these fatty acids, but at much lower levels than oily fish.
Omega-3 fatty acids work by reducing the ‘stickiness’ of the blood, making it less likely to clot. They also protect the arteries ...
