I disagree with the thesis of your argument and I find your perspective limited in scope. Seafood is the original brain food and the long chain omega-3 fatty acids and other micronutrients contained in salmon and other fish and seafood are important, in fact essential, for good health.

I would like to draw your attention to the work of Professor Michael Crawford, PhD CBiol, FIBiol, FRCPath, who is founder and Director of The Institute of Brain Chemistry and Human Nutrition http://www.londonmet.ac.uk/research-units/ibchn/index.cfm in London, UK. He is one of the world’s most eminent researchers into brain function and nutrition, with more than 300 publications. In the link provided, Professor Crawford discusses the vital role that seafood played in human evolution, the importance of seafood to human health, and the range of health problems, including an increase in brain disorders, caused by the decline in seafood consumption, see http://www.seafood.net.au/page/?pid=1003&nid=403

I hope you will modify your position based upon the science.
