Seems to me there are four classes of >beef (and I'd like to confine the

a simple answer: all depot and intramuscular fat is a mix of SFA/MUFA. the
amount of PUFA is small, otherwise it wouldnt stay solid in the noonday sun.
pigs have the most PUFA of mammals at 10%. so it makes no practical
difference from paleo to our age. there is much less DHA/EPA as has been
ponted out ad nauseum, but land mammals are not a good source at the best of
times, it was always obtained from fish.
