Extensive research has shown a clear link between diets rich in fish and other seafood, and a relatively low number of cases of typical "Western" diseases, especially cardiovascular diseases.
New reports prove time and again that the consumption of fish and shellfish is beneficial for the prevention of such diseases. Moreover, a fish-rich diet has a beneficial effect in psoriasis, migraine, eczema and rheumatism.
Such research base their conclusions in part on a comparison between the Eskimos and inhabitants of Northern Europe. Eskimos traditionally eat very much fish while northern Europeans especially eating meat from pigs, cattle, sheep and poultry. The most striking feature of a fish-rich diet is the high concentration of the fatty acids EPA and DHA.
The population of Greenland eat as much fat as Northern Europeans. However, many fish in the traditional Eskimo menu contains significantly more polyunsaturated omega-3 fatty acids and a relatively smaller amount of saturated animal fats.
In the traditional Japanese diet is fish the dominant factor. Scientific research has shown that the relatively low number of cases of typical "Western" diseases, such as cardiovascular disease, in Japan has to do with the big fish-oil consumption. The context shows the more apparent as more and more Japanese people move to a Western dietary pattern: the incidence of cardiovascular disease increases proportionally.
