What info does anyone have re tuna;  I am assuming it is
better to use water packed vs. that packed in oil.  Are
heavy metals that much of an issue?  The dolphin issue is a
concern  and I keep up on that but I do not recall the
current teaching, if I have seen it, on consumption of
tuna.  It is tasty and convenient;  dump a can on a salad
and you have an instant paleo meal.  I have also been eating
sardines packed in olive oil on top of salad for a paleo
type fast food lunch.  What say the list? rick
