Things were much simpler in the old days. We were given fish as children, told it was good for us, and ate it. Things are complicated now – tinned tuna has come under attack for its apparent high mercury levels. It isn’t the only offender, according to The Independent, who stated that sushi-grade tuna is just as risky (http://www.independent.co.uk/life-style/health-and-families/is-it-time-to-stop-eating-tuna-1970301.html). Aside from this, the Associated Press warned that dolphin meat and whale meat is just as high in mercury (http://www.google.com/hostednews/ap/article/ALeqM5hyiAYyO2-qaneyzCkw8qX4T2F1TAD9FJC58O0).
