    Logic behind the evil grain argument - question for Mark

    Primal Fuel
    Dear Mark,

    After reading your thoughts regarding the over consuption of water and the definiteive guide to grain, I had a question regarding the logic behind the primal eating argument. I would like to point out that I am very interested in aspects of your philosophy and have adopted parts of it into my lifestyle. My question is more out of pure curiosity and is in no way a criticism of your opinions and research.

    If I understood what I read correctly, your philosophy especially with ragards to primal blue print eating is that if it was good for our ancestors, tens of thousands of years ago, it must be good for us. Especially in respect to water and grain, you mention that in the hunter-gatherer stages of human evolution, it would have been highly unlikely for people to consume large amounts of water and that animal protein as well as vegetables, berries and nuts provided all the necessary nutrition. Another point you make is that because grain is a relatively recent introduction to our food, humans are not adapted for it and it is therefore not good.

    What i would like to know is that if we hypothetically take this argument back in time when people were discovering meat. We could also say that because we had lived so long without meat, scavenging and getting by on vegetarian sources of protein, etc, our system had not been developed for meat. Therefore too much meat which had suddenly become available would be bad for us, following the argument of the grain and water. If we stuck to this argument then we would think twice about eating meat and miss out on all the benefits.

    If we take this argument back to today, is it not possible that we simply are evolving again and we have an abundance of substance that may be good for us (such as water or grain) and that we simply have not realised the benefits of having these things freely available in large amount?

    My argument is not based on any science or research and I am sure many people will disagree with me. Like I said before, this is no way intended to criticise or bring into question your way of thinking, there is a lot of evidence against grain, etc. However it was just something I would really like to hear your opinion on.

    Sincerely,

    Andrei

    Andrei,

    There is a problem with your theory.

    When we began eating meat, the meat eaters got stronger, and smarter (larger brain size). The weak died earlier. This is called natural selection. The fittest survive, the weak die. We cannot evolve without this selection pressure.

    Today, we do not evolve in this way because that selection pressure does not exist. Today, it's easy to keep a grain-eater alive until they can procreate. And that is all that is necessary to eliminate natural selection. It doesn't matter that the same grain-eater will have a heart attack at the age of 45 (my father). He has already passed on the weaker gene (me).

    Hello, not sure where you're getting the water stuff. I haven't heard any anti-water arguments. (Also, you do know this is a public forum and Mark isn't going to necessarily see this, right?)

    You could hypothetically take the argument back to before we ate meat, but there's a difference in time scale -- we started eating grains just 10 to 15,000 years ago, perhaps less depending on your ancestry. That's not really all that many generations ago.

    But humans started their meat-eating omnivory much, much longer ago. Scavenging and then hunting later. I've heard the figure 100,000 years bandied around, but there's plenty of debates on that. And as ericfoster3 describes, this coincided with a big step in our evolution.

    Grains played a very helpful role in helping us expand civilization in the sense that they're cheap calories and so you could sustain a greater number of people without them starving to death. But that doesn't make them great for our long-term health.

    Now it may very well be that some people today are better suited genetically to cope well with grains long term than others, just like how Europeans seem generally better able to tolerate dairy than Asians. But as Eric points out, there's really not a lot of selection pressure for that to happen on a wider scale. And as a lot of people on this forum have found, they do seem to do better without grains, even if they don't have one of the "official" gluten-intolerances like celiac.

    Personally, while I find all the evolutionary arguments extremely interesting, I buy into this approach for two reasons:
    1) it seems clear to me that eating grains displaces other excellent foods like vegetables from people's diet -- foods with all the same or better fiber benefits, the added bonus of tons of vitamins and antioxidants, and a lower glycemic index.
    2) it works for a lot of people, and it's working for me so far, and ultimately that's what makes me happy food-wise.

    The assumption here is that we became humanoid-like creatures without meat, and then began eating meat.

    This, I believe, is false - us eating meat and becoming human-like creatures happened at the same time, and some would go as far as saying that we became "human" BECAUSE we eat meat. We do not have large stomachs and the need to feed most of the day like herbivores - our stomachs are small, efficient. While we can consume plant matter, most of us here accept that a purely vegetarian diet is inherently flawed. Grains are nowhere near this picture.

    Now, taking the overabundance argument - grains and water are NOT in overabundance for us - we are MAKING an overabundance for ourselves, allowing ourselves to reproduce in numbers beyond what is sustainable by the environment. Eventually, the system will topple over.
    - If it was cute and cuddly at some point, eat it. Ignore everything else. -

    - The body is animal. The mind, however, is not. -

    excellent response.

    plus - i think we were always omnivores, like the chimps who eat meat. i think the main difference in our diet came when we started cooking with fire or moved to locations where would encounter different food sources, eg shellfish.

    Otherwise, as far as I am aware, we have eaten the same way for MILLIONS of years. It's only been in the last few 1000 years we have not only changed our diet but irrevocably damaged our genetic "blueprint"

    I just wanted to suggest that you watch the NOVA documentary Becoming Human (you can watch it for free online). It is an awesome 3-part special on human evolution, and really illustrates the evolutionary pressures that resulted in today's human species (including our omnivorous diet).

    I also think we were always omnivores. I was just playing into his hypothetical for a moment.

    What most advocates of primal/paleo living have done is looked at the best available evidence of how people achieve good health in modern times. It happens to correspond beautifully to scientific evidence of how humans lived in hunter-gatherer societies; meat-eaters who also ate berries, vegetation, nuts and seeds. You can call it primal, or call it the Ultra Modern, Super-Scientific Diet to Prevent Diseases of Modern Civilization Such as Diabetes (T2) and Heart Disease. It's the same thing.

    The urban myth of 8 glasses of water a day has pretty much been debunked. Thirst works. Extreme climates and extreme exertion being the exceptions.

    I've heard some interesting theories that we (our critter ancestors that is) may have played at least a partial role in helping the dinosaurs go extinct. As warmblooded animals not tied to sunlight for warmth, we could raid their nests at night for eggs. Mmm, tasty-tasty eggs. (And in practice that means eating not just a yolk concoction like modern unfertilized eggs, that means we were eating almost-ready baby dinosaur meat too...)

    That's a much better way of explaining the point I was trying, and failing, to get around to above. Thank you!
