The history of the herring and with its decline the significance to health.
For centuries Europe seems to have partaken of the herring. With the coming of steam drifters in 1900 trawling for white fish became easier and they substituted for the herring and the taste for herring has been lost. Illnesses thrombotic, immune and inflammatory seem to be associated with the dietary change and modern biochemical science is busy showing that certain essential fatty acids present in vegetable oils and oily fish can give rise to essences obviating the need to revert to diets that may now be difficult to resume.
