but, if i'm doing this specifically for iron, it doesn't make sense to eat chicken, unless i'm eating liver.
my best choice is taking a more serious look at the fish, and what i want is fish that's grown indoors so it's not full of mercury. but, a quick google search actually suggests this is a general problem - aquaculture fish meat is generally deficient in iron, because the tanks are too clean.
ugh.
i have some anchovies in my fridge, still.
