    How many years will it take for our bodies to adjust to grain consumption?

    I'm just wondering how long you think it would take for our bodies to adjust whereby grains become the healthiest option? Will it every happen? It would surely be more sustainable although having said that by that stage the oil would have run out resulting in a substantially smaller population so maybe a mute point.

    There is a huge difference between talking about how to do something and getting it fucking done.

    Never. Humans are going to be selected out for another species. I'm going with virus'.

    Unless there's some sort of pressure actively selecting for it, a particular trait (in this case, running on grains) isn't going to be any more or less prevalent in a population. For humans in particular, it takes hundreds of thousands of years for any significant evolutionary change to occur, because of the length of our generations. To answer your question, it will take a very long time, if it happens at all.

    It can't happen. In the modern world, there is no 'natural selection' anymore. People get sick, and they don't need to rely solely on their immune system; we've got doctors and BigParma. People want food, and they don't need to be agile or intelligent to go track down some prey; they have grocery stores. People want safety, and they don't need to be strong or fit to fend for themselves; we lock up or separate ourselves from any dangers. There's no natural selection in most parts of the world because the strong and the weak survive. And without natural selection, there is no evolution. Thus, our bodies would never evolve to fit a grain-based diet even if the human race existed for another hundred thousand years.

    Virus? Ha! The [radical] Muslims are going to going to blow us all up before them.

    I'm going to strongly advocate that neither of my children have children of their own because the world is going to hell in a handbasket and I don't see it getting any better from here on out.

    Better to let our species die out and for mother nature to do her best.

    I don't see it happening. Evolution works slowly and we have already tampered with natural selection, so its not like a grain-tolerant gene will prevail over time.

    Also, it's not like it's a minor change. This would require hundreds of complex changes, perhaps of the gut wall to prevent absorption of anti-nutrients, of the immune system to react differently to gluten, of the liver and cardiovascular system to react differently to high blood glucose, etc., all while maintaining a gut wall that absorbs everything it currently does, an immune system that reacts to pathogens, etc. We've probably ended up with the genes we have because they already are the best possible balance of all those things.

    I'm doing that already with my kids.

    Won't happen because the human gut simply isn't long enough or complex enough to break them down. From your teeth down you're "built for" a meat-based diet.

    What many cultures do is pre-process cereals before cooking them by lactic-fermenting them. What they're essentially doing there is imitating in a container what happens in the stomach/s of a herbivore.

    Both points are made by those two ladies at the WAPF here:

    Caveman Cuisine

    So there you go: to eat the grain "as is" and not get sick (and to use it without penalty as the sole item of diet) almost everything about you would have to change from your teeth to your stomach. The changes would be so vast that, if (I think per impossible) they did take place, the resulting being would be so different from us as hardly to be recognizably human anyway.

    Could you call a being with a gut perhaps five times as long—and with, probably, a correspondingly smaller brain—"adapted"? I think no, he'd be a radically different being.
