For those who want to eat sometimes fish, I advise for many years ONLY sardine and tuna and maybe mackerel Now and then, some cod will probably do no harm.
You all know that fish has become a big problem, and salmon has become one of the most toxic foods! [not Alaskan salmon, very expensive and often not available]
Below is a short video of Dr Weil preparing a sardine dish.
