    I'm glad to see another paleo-guy in this thread. I think that makes about
    2.5 of us, where Eliezer seems to be the .5 :) (I'm still not clear about
    what Eliezer really thinks, given that he keeps disagreeing with me even
    while I keep trying to agree with him :-)

    I agree in principle with what you've written above, but perhaps unlike you
    I am not trying to "live" a paleodiet life-style. Like a lot of paleodiet
    proponents I am not opposed to adding supplements and other non-paleo
    substances to my diet when the evidence is strong that doing so is likely to
    have benefits.

    Perhaps the least paleolithic item in my diet is aminoguanidine. I take 200
    mg per day of this extremely non-paleolithic chemical. I do so because
    aminoguanidine is known to help prevent the production of Advanced Glycation
    End-products (AGE's). Appropriately named, AGE's are implicated in many of
    the diseases of aging, diseases which our paleo ancestors did not experience
    much due to their shorter life-spans.

    As mez points out, the forces of natural selection were blind to many of the
    modern diseases of aging. For that reason we cannot rely only on pure
    paleodiet theory to help us live longer. In terms of human evolution and
    longevity we are now in completely uncharted territory.

    In my view the paleodiet is, however, still the base diet upon which we
    should formulate an optimal diet. Again, it's a question of burden-of-proof.
    As I see it, any deviation from the paleodiet needs to be justified by solid
    scientific evidence.
