    The simple explaination is that grains and beans just didn't grow wild
    all over the place as we imagine. The bean and grain species we are
    used to are the result of several thousand years of directed evolution,
    breeding specifically for large fruit size and quantity. Their
    paleolithic ancestors just didn't produce that much fruit and no fruit
    of the size we are used to. Because of this, paleolithic people didn't
    invest much time into gathering these specifically because the energy
    payback was so meager.
    It was only when some individuals got the bright idea of selecting
    grains from the most fruitful plants to grow in isolation that the long
    process of domestication occured. The development of this technology
    spelled the end of the paleolithic era.

    Not necessarily. Pit cooking techniques are paleolithic in nature and
    do not result in the charring that generates the carcinogenic compounds
    moderns are so afraid of. Ever been to a new England clam bake or
    Hawaiian pig roast? That is non-carcinogenic paleolithic cooking.

    I beg to differ. Anthropologists have developed evidence that
    neanderthals ate a 90% meat diet, where cro-mags ate about 60% meat,
    depending on habitat.

    Yes, and paleolith proponents are 'down on vegetarianism', as Harvey
    says, specifically for energy and power reasons. Look at any
    vegetarian. Most are waif thin. Only the most disciplined are able to
    maintain any sort of significant muscle mass. Imagine such individuals
    trying to take on a sabre tooth or cave bear, trying to track a woolly
    mammoth or red deer for days, then having the energy to haul the kill
    by hand over miles of rough and hostile terrain, fighting off
    scavenging packs of hyenas.

    Outside of lactose intolerance being an indicator that dairy was not a
    common paleolithic food group. With modern supplements, yes, you can
    make up for shortfalls in the vegan diet that way, but what is the real
    uptake? I was under the impression that the uptake of supplements was
    rather poor. It is also kinda dishonest, much like my article on how
    the Nearings cheated on their "Good Life" with inherited wealth.

    But that isn't the point, either. The point of living a paleolithic
    diet is to live healthfully without modern interventionist techniques
    like supplements, caloric restriction, body building and aerobic
    training. It naturally avoids foods which the human animal did not
    evolve to eat.

    Watch out. I have found that many of the so-called 'range fed' meats
    are stall fattened with corn for several months prior to slaughter.
    While I don't mind eating these once in a while, if I cannot obtain
    truly wild meat, I will eat naturally lean meat like fish, turkey,
    ostrich, emu, buffalo, etc.
