Many folks put red meat and seafood into an "A" rank because of dense micronutrients and low omega-6 fats, with pork and poultry falling into a "B" rank--possibly because the pastured and wild sources are harder to find in the US. Personally I rotate all of them for pleasure and just in case I'm getting too much iron, mercury, etc.
