Gone Fishin'

The Paleolithic Diet consists of meat, vegetables, fruits, nuts, and a few other odds and ends like honey and insects.  Seafood is not a Paleolithic food, though it is often lumped in with other true Paleo foods.

Loren Cordain explains here that there is no fossil evidence that seafood played a major role in the Paleolithic diet.  Yet Cordain does recommend seafood to be included in modern diets, mostly for its "good" fat.

Hunter-gatherers ate all sorts of nasty things, like brain and bone marrow, to obtain fat.  Since most modern people aren't willing to go that route, seafood can be an acceptable substitute.  But what are the drawbacks of seafood?  I don't think it's ever been fully discussed or researched.

After all, grains and dairy can look innocent on the surface until one digs deeper.  Then you find out that these foods aren't just neutral sources of calories, but they are foods that can cause health problems for many people.

What could be the negative effects of seafood?  Obviously, mercury is an issue but I haven't researched it much further.

I don't eat a lot of seafood, but I do take cod liver oil or fish oil to get omega-3 fats.  In Paleolithic times, omega-3 fats came from the meat.  Modern grain-fed meat is notoriously low in omega-3.

I have been thinking about buying some grass-fed beef and utilizing that to get my omega-3 fat.  Most regular stores (or even health food stores) don't carry it, so I will probably have to order it.  This site details some of the benefits of grass-fed beef as opposed to grain-fed beef.
