    Because I look at the labels and do the math and get decent numbers. Some
    multi-grain bread here would give 80g of protein and 160% of fiber, plus 100%
    of iron and lots of various B-vitamins. Some conventional pasta would give
    70g of protein and 90% of fiber. Like I said, they're not complete foods, but
    they're not horrible. Eat a bit less, eat an orange and a carrot, or some
    broccoli, and you're doing pretty well, or better than lots of sugar-fed
    Americans. Calcium shortage, though.

    Oh, definitely. But you have to get calories too. And the link between
    saturated fat and heart disease seems pretty strong, so I'd be careful with
    the meat and fowl.

    And I'm on a budget. Grains and beans are cheap. (I miss Trader Joe's and
    whole wheat pasta which wasn't a price ripoff.)

    Look, my main objection is people acting as if grains are empty calories.
    They're not. Maybe Wonderbread is close to it, but there's more to the world
    of grains than that. Bleached and refined flour is not all there is.

    They might have been using those stones since before the Neolithic happened
    elsewhere. And this is Australia; the next season is pretty unreliable and
    the aborigines did fine without planting and anyway the European invasion
    pretty much disrupted everything.

    On the flip side those are unselected grass seeds -- which are, after all,
    simply seeds. If you want to say large and starch-boosted agricultural
    products are unhealthy I don't think the Australians contradict you.

    The other way of looking at all this is that while it's hard to know exactly
    what the Palaeolithics were eating -- plants don't preserve well, and studies
    can be biased by the hunter or gatherer biases of the researchers -- there's a
    population in the world today which lives longer than everyone, which unlike
    alleged yogurt-eating Caucasus folk is documented thanks to a modern
    bureaucracy. I speak of the Okinawans, who have more (and more active)
    nonagenarians than anyone, and who eat a lot of rice. White rice, even. But
    they also eat lots of fish and vegetables and drink lots of green tea and
    don't eat much land meat or dairy and also seem to avoid stress. And their
    children go off and live like Westerners and die early, so genetics don't seem
    a likely culprit here. Or at least so says _The Okinawa Program_, from which
    I conclude having some grains in your diet is not going to kill you.

    I do have to amend the "lots of"s above; apparently another cultural feature
    of old Okinawans was "eating until 80% full", so there may be a mild
    calorie-restriction component going on here too...
