Talking Past Each Other

I have found myself defending paleo a lot more recently.  Sometimes against the usual suspects, but also against criticism (and I use that word very loosely) from quarters I wouldn’t have expected.  I am well past trying to defend paleo to those who simply refuse to listen and especially to those whose only criticism of paleo is “I like bread”.  Where my greatest frustration lies, however, is when I hear people talking about modern humans being mismatched to their environments, to not be adapted to the food and inactivity exposures, to eating too much fake food and not enough real food, to sleep, stress, and circadian rhythms, to high glycaemic diets, to not consuming enough quality protein, etc., etc., and then having these very same people tack on the statement “oh, and paleo is a fad and totally bunk.”

Perhaps some of my frustration with this is born from a degree of agreement with them.  If I was anyone other than “That Paleo Guy” and I was looking at the most recent and increasingly common permutations of paleo for the first time, I’d perhaps come to the same conclusion however.  It would be very easy to look at some of the common blogs, the proliferation of paleo treat and dessert recipes, the starting up of commercial paleo cookie dough, and the perpetual (and mind-numbing) media stereotype of the sausage-and-bacon-eating-vegetable-dodging-bearded-Neanderthal-resembling-multi-modal-group-fitness-exerciser, and to view this “paleo diet” as something rather contrived.  Indeed, on the fringes of the movement, as is often the case on the fringe of any movement, it probably is.

But then there are a core group who are probably a bit more moderate/conservative when it comes to all things paleo.  This is the group I identify the most with.  A group which promotes real, whole foods, over and above highly processed (be it commercially processed or DIY home-kitchen processed) aggregations of ingredients made into edible food-like substances; a group which promotes physical activity patterns which involve not sitting, moving slowly with high frequency, applying some form of resistive load on a regular basis, and occasionally pushing oneself hard and fast, without getting all religious and obsessive about it; a group which promotes and respects the power of a good night’s sleep (and won’t sacrifice that just to worship at the altar of the group fitness class); a group which advocates sensible sun exposure without sun-baking and burning; a group which promotes and advocates for more human forms of social interaction (face-to-face vs. online).

The common thread through all of this is that there is nothing particularly new, novel, extreme, dramatic, faddish, or shocking about any of this.  In fact, unless I was doing all of the above in a loin cloth whilst chewing on some raw steak, all in the name of some long-lost ancestor, most media outlets wouldn’t be interested in covering any of it.

Paleo

What is PaleoMy point being, most of the moderate paleo/primal/ancestral/evolutionary biology promoters are not really saying anything that is much different from that which many in the “mainstream” are saying.  I suppose the difference sits with our “why”.  We are all largely stating the “what” and most of the “how” the same.  We (paleo) are just stating the “why” – evolutionary mismatch – a bit differently to many.  That said, is our evolutionary mismatch viewpoint really that radical?  I don’t necessarily think it is.  The Chief Science Advisor to the New Zealand Prime Minister, Sir Peter Gluckman, would perhaps say it isn’t so much a radical view point.

Mismatch: Why our world no longer fits our bodies

What is frustrating, is the amount of talking past each other that is occurring.  Some of this is born out of the paleo/primal/ancestral/evolutionary biology (PPAEB) message being in direct competitive conflict with those who have a $book/$plan/$product/$answer to the problem, that is already largely addressed in a free-to-air, open-source way by the PPAEB movement.  When you perhaps want people to listen to [your message] rather than that of those silly paleo types, it is easier to perhaps cite the most extreme and ludicrous examples from within that movement (or create your own straw man version of said movement), and show yourself to be putting them and their silly notions to bed.  For the most part, I think much of it is just plain ignorance.  I know many people who have heard of paleo, vaguely, haven’t really looked at it because it is something to do with replicating what cavemen did and “that is just silly”, and so haven’t looked at it much from there.  These people tend to rely, heavily, on the same straw man “debunking” arguments presented by others (cue reference to a TED talk where someone debunks paleo…).

As everyone has their own definition of what “paleo” is, I suppose now would be a good point to summarise my own definition of it.  To me, paleo is not about re-enactment, or about a just-so story – doing something because that is what our ancestors did.  “Paleo” has simply always been a point in time – the palaeolithic – a point in time up to about 10’000 years ago – a point up to which a good portion (not all) of my biology evolved based on constant inputs my ancestors received in the environments in which they lived.

Because of the sheer weight of human evolution which took part up to that point, and due to some of the changes that have occurred since then (particularly in the last 40-50 years), it seems like a good place to START (as opposed to finish) when trying to clear some of the signals away from the noise in our modern ecology.  Can we say that the palaeolithic was the peak of humanity in terms of health? Absolutely not.  But given that the world of 2013 seems not to be either, and that our physiology seems very confused by all the multiple inputs it is receiving, then winding the clock back a bit and stripping away some of the more recent signals before retesting them one at a time, seems to be a good approach.  Establish a good and strong baseline and test some theories from there.  Paleo (food, sleep, activity, sun, socialisation…), to me then, is not the end game, but a baseline with which to test things from and a place from which perhaps some “re-matching” can occur, in terms of the signals/inputs my physiology works best with.

Quick example.  I am of Northern European descent and have lactase persistence – I can consume dairy with no gut upset at all.  Ice cream – FTW!  But I get sinus inflammation when I do have dairy.  I only discovered this by adopting a dairy-free paleo diet and repeatedly retesting…re-exposing myself to dairy.  No dairy – no sinus inflammation.  Add dairy – sinus inflammation returns.  No grains – no gut and skin problems.  Add grains – gut and skin problems return.  I needed a good baseline from which to test these things from, however.  This is the essence of an elimination-challenge approach or something like Whole30.

Many of the common and current criticisms of paleo are not anything new and are issues which have been discussed and acknowledged within the community itself.  Chris Kresser sums it up well here, in a statement from 3 years ago…

Paleo

I too have considered a ‘name change’ – a shutting down of TPG and a move away from paleo, spurred mostly by wanting to distance myself from the paleofication brigade.  But in the end, I don’t see much of a point.  Paleo, to me, is a short-hand way of referring to the viewing of diet and lifestyle through an evolutionary lens, in order to understand where we are currently at and what we need to do.  As far as food and nutrition goes, Whole9’s elevator pitch is the essence of what a paleo diet means to me…

nutrition in 60secPaleo, as a way of eating, is also as much about what I’m not eating.  Perhaps I should call myself “That Anti-Neolithic Guy”, though that is as much fraught with interpretation problems as “paleo” is.  Yet this lifestyle that I live and promote manages to avoid the vast majority of the foods on the NEEDNT food list, as published in the New Zealand Medical Journal.  Indeed, there is only 2-3 items on that list that I personally consume (butter, coconut cream, and dark chocolate), and probably only a half-dozen all up which fall into the general category of being “paleo”.  I just replace all of the things on the NEEDNT list with real foods rather than the equally as junky “healthy” replacements suggested in that piece.

NEEDNT List

I also view “Paleo” as a short-hand for using evolutionary biology as a starting point for inquiry into human health and well-being (I should have perhaps called myself “That Evolutionary Biology Guy”).  I really love the inquisitive and collaborative nature of many of the people in this and other movements which fall under the umbrella “Ancestral Health”.  Indeed, I think a multi-disciplinary approach is the best way forward for finding solutions (something we had drummed into us as part of my Sport Medicine diploma – that you are part of a multi-disciplinary team rather than any one person being an authoritarian – a belief that was very absent when studying nutrition).  The editors of the Journal of Evolution and Health sum it up well here…

JEVO

Evolution, as an avenue of inquiry, and a multi-disciplinary approach, allows us to talk more broadly and to come at a problem from different angles to allow us to source the answer.  As an example, I hark back to a popular magazine piece examining the Paleo Diet, and some valid criticisms levelled at it by Sir Peter Gluckman:

NS GluckmanGluckman brings up two good points.  Firstly, that there is no one Palaeolithic diet to go back to – that there was lots of variation in hunter-gatherer diets.  He is quite correct here, which is why I teach my corporate groups that there is no singular hunter-gatherer diet…

HG dietsSo lots of variety in hunter-gatherer diets, but we are close to having an almost singular Western diet (the Standard Western or American Diet).  Hence why we prescribe heavy reductions in the typical Western foods and more of a leaning toward a Paleo template than a set diet. If we recognise that the SWD is not the best for us, and that modern agriculture has contrived the food supply so much that winding the clock back 40-50 years is no longer enough of a correction, it would seem we might have to go back a bit further in time to establish a good baseline.  Chris Kresser again…

Cookie cutter

Template

Gluckman, as an evolutionary biologist, mentions how we have adapted to carbohydrate in our diet by virtue of carrying several copies of a gene coding for salivary amylase – an enzyme in our saliva which helps us to digest starches.  This is true and builds on our knowledge of foods we might be best adapted to eating (mmm… kumara and yams).  But then a plant biologist can add to this discussion further by showing that some plants, such as grains, have the ability to inhibit salivary amylase (and other enzymes in our digestive system), presumably as some sort of protection system for that particular plant;

Inhibitor activity against digestive enzymes, such as α-amylase from human saliva and porcine pancreas and trypsin from bovine pancreas, of three cereal grains species were studied as potential components of nutraceuticals strengthening diabetes and obesity treatment. Significant differences were demonstrated: the highest anti-tryptic activity was found in the grain of the rye varieties studied, whereas the grain of the wheat varieties had significantly higher ability to inhibit α-amylases from human saliva and porcine pancreas. Additionally, seeds of Puma, one of the studied wheat varieties, demonstrated especially low anti-tryptic activity. Such a beneficial arrangement of inhibitors, i.e. high level of inhibitors of α-amylase from human saliva and porcine pancreas and simultaneously low level of trypsin inhibitors from bovine pancreas, indicate the possibility of the application of seeds with such properties to the preparation of nutraceuticals for people with obesity or suffering from diabetes.

By getting more people with an interest in this area talking to each other, rather than at or across each other, we can, collectively, come closer to some answers.  In the above example, starches from roots and tubers, likely good; starches from grains (particularly modern variants), probably not so much.

As a movement, we don’t have all the answers, and when something works we might not necessarily know why.  Yet we are an inquisitive bunch keen to find out why.  I suspect in many instances, we will never know exactly why something has worked the way it has, with it simply being a case of the whole is greater than the sum of the parts, be it for food or any other aspect of health and well-being.

CMJWe are, after all, talking about highly complex systems here.  Not everyone (likely the majority of people who stand to benefit) really want to know of this complexity.  Perhaps this is where we need a narrative or heuristic, which allows people to get the general idea, expedite their understanding of it all, and allow them to apply some basic principles to their lives.  The paleo narrative can be that heuristic, though I agree it can be stretched too far at times. Taleb captures the benefits and imperfections of these heuristics here…

heuristic

I want to highlight a common example of where many of us seem to be at crossed purposes in our discussions around health and nutrition – whole grain foods.

Back in 2005, the Australia & New Zealand Food Authority (ANZFA), under petition from food manufacturers, changed the definition of a whole grain as it can be used in food production and labelling.

ANZFAIn effect, this definition change allowed food companies to take a whole grain, dismantle it to its component parts, and reconstitute them as something which is nothing like the original whole grain as long as the component parts are part of the mix in roughly the same proportions, concurrently assuming that the sum of the parts are at least equal to the whole [grain].  As you can see from the screen capture above, this is because it was really only brown rice and unpearled barley (and likely whole, unrolled oats) which fitted the definition of “whole grain”, and these products were of low marketability for the food companies.  This is the rule change that allows products like Cheerios be marketed as whole grain, even though they are nothing like any of the original source grains.

Jump forward a few years and we have this entry on a blog from University of Sydney researcher, Jennie Brand-Miller;

‘Consume more whole grains is enshrined in dietary guidelines around the globe and has become something of a mantra by doctors, dietitians and nutritionists. But does the science stack up to scrutiny? When you see ‘whole grains’ on front of pack, do you assume it’s the real McCoy? Has it got everything that the original whole grain had – all the micronutrients and characteristics that make whole grains into health foods? Well, I think we are being hoodwinked. Whole grain products might have started with the germ, the endosperm and the bran of the grain, but in many cases, the finished product has been cooked, flaked, toasted, puffed and popped beyond recognition. It’s a long, long way from the grain that came in nature’s packaging…

I encourage you to read the rest of the entry as it makes for interesting reading.

More recently, Professor Jim Mann, from the University of Otago, described bread as “bags of glucose” in a talk on the Nature of Carbohydrate in the Management of Diabetes… and called into question just how much of a source of whole grains “whole grain” bread is.  Prof Mann went on to discuss the cellular structure of these products, suggesting, in effect, that high carbohydrate diets, where the sources of carbohydrate have their cellular structure broken down and destroyed (ground and refined – even when labelled whole grain), lead to a loss of glycaemic control and subsequently predispose people toward metabolic dysfunction and diabetes.

Prof Mann’s comments echo those in a recent paper on this topic;

Comparison with ancestral diets suggests dense acellular carbohydrates promote an inflammatory microbiota, and may be the primary dietary cause of leptin resistance and obesity.

A novel hypothesis of obesity is suggested by consideration of diet-related inflammation and evolutionary medicine

Furthermore, nutrition transition patterns and the health of those still eating diverse ancestral diets with abundant food suggest that neither glycemic index, altered fat, nor carbohydrate intake can be intrinsic causes of obesity, and that human energy homeostasis functions well without Westernized foods containing flours, sugar, and refined fats. Due to being made up of cells, virtually all “ancestral foods” have markedly lower carbohydrate densities than flour- and sugar-containing foods, a property quite independent of glycemic index.

Thus the “forgotten organ” of the gastrointestinal microbiota is a prime candidate to be influenced by evolutionarily unprecedented postprandial luminal carbohydrate concentrations. The present hypothesis suggests that in parallel with the bacterial effects of sugars on dental and periodontal health, acellular flours, sugars, and processed foods produce an inflammatory microbiota via the upper gastrointestinal tract, with fat able to effect a “double hit” by increasing systemic absorption of lipopolysaccharide. This model is consistent with a broad spectrum of reported dietary phenomena.

A diet of grain-free whole foods with carbohydrate from cellular tubers, leaves, and fruits may produce a gastrointestinal microbiota consistent with our evolutionary condition, potentially explaining the exceptional macronutrient-independent metabolic health of non-Westernized populations and the apparent efficacy of the modern “Paleolithic” diet on satiety and metabolism.

I challenge you to read through this paper and to listen to the Prof Mann talk and not see/hear the overlap.  It is the same ground.

The above paper references “ancestral foods” and a modern “Paleolithic” diet as a potential pathway for dietary exploration, as does this recent Australian-authored paper;

Wholegrains: Emerging Concepts, Controversies and Alternatives

Intake of wholegrain foods has been associated in large prospective cohort studies with decreased rates of diseases such as type 2 diabetes, ischaemic heart disease and hypertension. Multiple mechanisms for the protectiveness of wholegrain foods have been reported. Health authorities in western countries recommend wholegrains as one of the major food sources in a healthy diet, otherwise rich in vegetables, legumes and low-fat dairy.

However, the existing evidence for the intake of wholegrains is highly subject to confounding. Many of the results seen in the prospective cohort studies have not been borne out in randomised controlled trials or good-quality meta-analyses. The recommended intake of wholegrains suggested in some countries is well above what there is evidence for. Products labelled wholegrain have variable quantities of the intact grain and differ widely in their effect on blood glucose. Excessive quantities may add to glycaemic load, and anti-nutrients in wholegrains may have adverse health consequences. With the rate of diabetes and obesity increasing, some researchers have questioned the role of grains as part of a healthy diet.

Palaeolithic diets, those that are more in keeping with our evolutionary legacy, contain no grains or dairy, but are rich in vegetables, meat, fish and eggs, with the inclusion of some tubers. Smaller trials in animals and humans comparing a palaeolithic diet to a grain-based diet show improved metabolic profiles in the former.

This is a paper published late last year (2012) and echoes Brand-Miller’s comments from almost exactly 2 years earlier regarding the confounding of evidence related to whole grain intake, and Mann’s more recent comments regarding products labelled as whole grain having profoundly variable effects on blood glucose control.  Again, this paper also references looking toward our “evolutionary legacy” for answers and recommends more nutritious, “cellular” sources of carbohydrate such as vegetables, fruits, and tubers.  We see recognition that ancestral foods and diets are generally lower carbohydrate than standard Western diets.

The Dietary Intake of Wheat and other Cereal Grains and Their Role in Inflammation

Wheat is one of the most consumed cereal grains worldwide and makes up a substantial part of the human diet. Although government-supported dietary guidelines in Europe and the U.S.A advise individuals to eat adequate amounts of (whole) grain products per day, cereal grains contain “anti-nutrients”, such as wheat gluten and wheat lectin, that in humans can elicit dysfunction and disease. In this review we discuss evidence from in vitro, in vivo and human intervention studies that describe how the consumption of wheat, but also other cereal grains, can contribute to the manifestation of chronic inflammation and autoimmune diseases by increasing intestinal permeability and initiating a pro-inflammatory immune response.

The paleo/evolutionary biology approach is to suggest that, due to the relative novelty of grains in the human diet, we haven’t been able to completely overcome their numerous defences against digestion, which when consumed in a modern context, and in the relative large doses we get them in the modern diet, can cause us numerous health issues.  Interestingly, in one of the papers I linked to earlier, researchers are looking to exploit these very properties of grains as a novel treatment for obesity.  The suggestion is that researchers may be able to engineer plants [grains] which selectively shut down our starch-digesting enzyme, amylase, thus reducing how much carbohydrate we absorb.  If you think this sounds suspiciously like engineering “low-carb” grains, this is exactly what it is.  The only problem (not the only problem, as I see it, but the only problem for the researchers) is that these plants also disrupt protein digestion with fairly disastrous consequences.  Full paper here.

More recently, a prominent New Zealand economist has joined the nutrition debates, attacking a New Zealand food production system that is awash with Fake Food;

Why do we expect scientists and factories to make better food than Mother Nature? The fact is that nutrition science is a fledgling beast, and simply hasn’t been able to keep up with the innovation in the food industry. The whole paradigm of taking foods, processing them into their constituent parts, then recombining them in weird and wonderful ways to ‘add value’ is the stuff of mad scientists. Just as Frankenstein’s dabbling created a monster, so too has the dabbling of food scientists created Frankenfoods. There are a many examples where this scientific approach to food has gone horribly wrong; including milk formula and trans fat. There are also emerging examples where isolating food components from their natural state turns them from benign to harmful, including fructose, carotene and fibre.

So, then, from multiple quarters, we would seem to have a strong degree of convergence taking place.  Many, be it career academics, researchers, clinicians/practitioners, and lay people, are all coming to largely the same conclusions on very many areas in nutrition.  We are all perhaps using slightly different language, and there are definitely some nuances to each, but the basic skeleton is the same.  One group might talk about eating a low glycaemic index and load diet, whilst another might call this low carb.  One group might discuss omega 3: 6 ratios, whilst another might just say to avoid margarines and vegetable oils whilst eating more fish and seafood.  One group will talk about altering our sodium to potassium ratio, whilst another might say we need to eat less processed foods and eat more fruits and vegetables.  One group might describe a meal containing salmon, eggs, and vegetables coated in olive oil as Mediterranean, whilst another will call it Paleo.

Real Food

Real Food

We are all largely on the same page.  Yet for reasons of ego, perceived authority, conflicts of interest, and whatever else, we get caught up in these semi-religious debates around whose food god we should all be worshipping.  Strangely, each of our chosen deities seems to just eat real food.  We are talking past each other – talking at crossed purposes.  Nobody expects 100% agreement on anything as there is so much we just don’t know.  Scepticism and robust debates are healthy, allowing new information to be thrown into the light.  I have been to the Ancestral Health Symposium for the last 3 years – a symposium where attendees, for the most part, support a similar paradigm.  Yet even within this group there are differing viewpoints and subtle (and sometimes not) differences in approaches.  But it is largely hair-splitting.  There is no expectation that everyone will agree on everything (see the Jaminet vs. Rosedale “Safe Starches” debates as a good example).  But it would be nice to see at least some recognition and acknowledgement when we all agree on the same thing.  Instead, we have people calling Paleo a fad or fringe (and trademark infringement), academics bickering amongst themselves about who has the authority to be saying what, and a dietitian promoting a whole food-based diet whilst simultaneously making up stories about a movement that promotes largely the same thing.

Debates in New Zealand around low-carb (LCHF) diets have shot to prominence recently, with people again seemingly talking past each other and getting caught up with the label applied to the end plate of food.  The plate pictured above could be called a LCHF meal, or it could be called a Paleo meal, or it could be called a Mediterranean meal, or a Heart Foundation meal, or just a plate of real food.  Yet, without actually referencing THE SAME plate of food, these individual labels are proving divisive; like a pack of wild dogs scrapping over the same bone.

The ‘establishment‘ response to a call from the low carbers to change our eating habits is that they have reviewed the evidence for lower carbohydrate, higher protein diets (in a real food context, fat and protein often travel together), stating that they offer no advantage beyond the two years that they are predominantly studied for.  This becomes an interesting notion when I know that what the low carbers are suggesting is a diet free of processed food (including the many and varied forms of grains, which, as per above, we all seem to agree are problematic in their most modern guises) and rich in vegetables, fruits, and whole protein sources and their inherent fats.  In essence, the academic nutrition establishment seem to be suggesting that real food diets offer no advantage (for weight loss) beyond two years.

When you see what the academic research version of a low carbohydrate, high protein diet is, it becomes very easy to see the flaws and even easier to see that we aren’t even arguing about the same thing.  The following is from a recent thesis submission to the University of Otago.  The thesis itself is a tome of work, and I genuinely admire anyone who can commit themselves to such a project.  It is a huge effort and you can see how difficult it is to conduct such research on free-living humans.  I really encourage you to read the sections where the study participants gave feedback on all the difficulties they had with this diet research (some of which I think is due to inherent flaws in the study design, but then other aspects are just inherent to dealing with real humans).  The real money shot, however, is the head-to-head comparison of the foods feed to the low-fat (high-carb) and the high-protein (low-carb) groups – look at these bearing in mind all the information above on whole grain foods…

High Carb Study

High Carb Study Diet

High Protein (Low Carb) Study Diet

High Protein (Low Carb) Study Diet

I’m not going to do a full analysis of the thesis here (a whole new post in itself), but it becomes easy to see, qualitatively, that we are all discussing quite different diets even when referencing the same macronutrient terms (underscoring the futility of macronutrient-based arguments).  The conclusion from that study: “This study demonstrated that a high protein or high carbohydrate diet is equally effective for weight loss. Dietary compliance however was poor and drop out rates were relatively high.”

Instead of talking at each other and talking past each other I think it is time we started talking to each other in a way that allows us to use the same language.  It is time we acknowledged where there is common ground and to debate, robustly and respectively, areas which need threshing out further.  No singular authority has all the answers; all the practical solutions.  But we actually agree on a surprising number of areas, and we all seem to certainly agree with what ends up on our plates, for the most part – real food.  Let’s start talking about that.

  1. Thank you Jamie for this excellent post. You have highlighted eloquently what happens when we allow dogma of all kinds to over ride rationality and common sense!

  2. The term “paleo” that you describe, and it sounds like you would prefer, is what could be referred to as a “design pattern” in various fields (architecture, software development, etc):

    “a design pattern is a general reusable solution to a commonly occurring problem within a given context in software design. A design pattern is not a finished design that can be transformed directly into source or machine code. It is a description or template for how to solve a problem that can be used in many different situations.”

    However, the “paleo” you sound less comfortable with is the brand/marketing version which, again drawing parallel examples, is like the catch-all term “The cloud” which draws some amount of cringing from those of us that have worked in software development for a while:

    http://en.wikipedia.org/wiki/Cloud_computing

    Note the long history, (back to the 1950’s) before it hit buzzword status. The tech industry is awash with similar examples, largely as they give marketing folks something to sell without really understanding or caring about the real meaning behind them. If software developers were to spend any amount of time ranting about these buzzwords and the bullshit that goes along with them we’d get nothing done. On the other hand if it wasn’t for marketeers (and in some of the projects I work on that includes using such buzzwords to get research grants) there would be less projects to actually work on.

    I read a nice little bit of wisdom just yesterday, which I’m sure rang as true to the author’s own pursuance of being a tolerant educator, as it did a piece of educational wisdom for her readers:

    “The first thing many of you have to do is to learn to accept the trivial annoyances and small misfits of life as a matter of course, for to give them attention beyond their deserts is to wear the web of your life to the warp.

    Elbert Hubbard never said anything better than that. Have that reproduced in motto form and put it on your bureau, and repeat it fifty times daily.”

    (Realising of course that these days that could be cheesily summarised as “Don’t sweat the small stuff” but it doesn’t quite have the ring does it?)

    On a more practical front: Have you considered a subtle renaming of this site to ‘Jamie Scott – “That Paleo Guy”‘ or such like. This article suggests you’ve outgrown a moniker that now has meanings beyond what I expect was initially a bit of tongue-in-cheek; i.e. it’s now “that paleo guy, great, where do I find the cookie recipes?” v’s “who’s he? Ahh, that paleo guy?”.

    • Thanks for your comments, Nick.

      On the one hand, we shouldn’t sweat the small stuff, but on the other hand it is frustrating to watch the fundamentals of what Paleo originally was get baked out of it by the newcomers to the movement (who want to have their paleo cake and eat it too) and have those who are opposed to it as a point of inquiry dogmatically create works of fiction about what Paleo 2.0 is (or was). Do we just let everyone tear it to shreds whilst quietly slinking off and reemerging under a new name, or do we mark a line in the sand and stand up for it? For now, I’ll go with the latter. So a name change isn’t imminent.

      • Rather than suggesting that you “don’t sweat the small stuff” my point was more that the same irritations you express in this article have been expressed across history (I found numerous quotes in the selection of old skool health books I was skimming on project Gutenberg that expressed frustrations I’m sure you’d have empathised with) and across other professions. Pleasedo continue to sweat the small stuff, stand up for it and have a good rant about it when needed. As will I.

  3. Splendid.
    LCHF stands alone in the sense that carbohydrate restriction is already a proven medical technique.
    But the benefits of LCHF were usually explained in evolutionary terms in the past. So I see LCHF as the “serious” member of the Paleo family. It can work without Paleo, but deserves to stay connected to those roots.

    • Medical definitions and keto diets aside, the most common and practical form of LCHF overlaps extensively with the most common form of paleo/primal (imagine a Venn diagram if you will), being a plate of food which is generally LOWER carbohydrate than standard Western meals, and HIGHER in fat (generally a mix of monos, polys, and safas). And quite rightly, evolutionary biology underpins both camps, and both still have question marks around them due to gaps in knowledge and understanding (not enough to not be doing them, however).

  4. I love this post Jamie, thank you so much! This was one of the things that we wanted to talk to you about when we interviewed you and Anastasia for the podcast (but ran out time).
    We’ll have to get you back on for a part 2 (and 3, 4….)
    Cheers
    Jo :-)

  5. Good post Jamie. Agree with pretty much all of it. Must have taken a while because its long….So (tongue firmly in cheek) you wrote (about the LCHF and more in NZ “these individual labels are proving divisive; like a pack of wild dogs scrapping over the same bone” – isn’t that paleo though?)

    • Kevin,

      To me, paleo is the practical end of evolutionary science, with information flowing both ways between the two. That people will exploit something for their own (often commercial/egotistical) gain is nothing new, and this happens in every field of health and well-being. Those who treat it as the next latest fad will inevitably move on to new pastures like the plague of locusts they are. But the fundamentals of it all will remain – we still need to eat, sleep, move, love… and we need to do those things as a result of our evolutionary heritage. The label might change but those basics of humanity won’t. So the fad of adding the paleo prefix to everything in order to rationalise your baked goods habit – yes, it will and should come to a tragic and comical end (I really hope it does for the soulless sellouts who are selling the people paleo donuts). But the ‘real’ paleo/primal/whatever-you-want-to-call-it, where we live in such a way as to meet the fundamental human needs, well that dies with the last humans.

  6. Very important and mostly acceptable reflections. I try to call paleo ” Evolutionary Guided Nutrition” which takes into account the fact that evolution continue as we speak. In practical terms it can also be called “Supermarket’s Edges Nutrition (except for bread and milk to the sensitive). The thing is we don’t always know how many copies of sliva amylase gens we have so using Paleo as SAFETY templet (as I think we should be used) will most frequently result in reverting to the longest lasting common human nutrition namely meat and animal fat which were the fundemental components of the Paleolithic diets regardless of what “Paleo experts” like Gluckman (or you) say. Just look at your own “Hunter Gatherers Diet” slide if presented in terms of macronutrients taking into account that the Sun eat Mongongo nuts and that it is not Paleo but ethnographic, The varietion practically disappear even in non-agricultural non-Paleo diets that you present. See the slides of my presentation at AHS13 for why I came to the conclusion that the Paleolithic diet was as (un) varied as a wolf diet, meaning meat, fat and the infriquent, seasonally abandent plant food. http://www.slideshare.net/ancestralhealth/miki-ben-dor-ahs13-slides?from_search=2

  7. Brilliant. You have thoughtfully laied out what I’ve been thinking through during the last year and a half on “paleo” all in one nice post.

  9. I think Kurt Harris summed it up well about a year ago with this comment. I’m all for eating healthier but paleo as a “meme” is a mess.

    “i am currently confused as to what value there is in a paleo/ancestral approach to nutrition and health.”

    “I am not sure there is any now. There might have been, but just from the total inability to coalesce around core recommendations, and the radical variability in approaches we see under the label, anyone could be forgiven for thinking paleo is a lot of ideologically-driven a priori narrative-based dietary faddism.
    OK, everyone agrees that a preference for real food is smart and that we could ditch wheat and sugar without ill effects if we want, but otherwise there is no “core curriculum” as it were.
    We still have factions claiming with a straight face that Milk is a cause of multiple sclerosis (!!) and other factions recognizing that pastured milk products might be some of the healthiest traditional (definitely not paleo) real foods you can eat.
    And we have factions that cling to the shunning of legumes on a basically theoretical (if weak) basis which as far as I can tell has zero support in epidemiology and little other evidence to support it. In fact, it seems to be an artifact preserved from the original conceit of Eaton and Cordain that anything “we could not have eaten easily” when we were not even who we are now, cannot be good for us. This is a conceit that has never made an iota of sense for me. other than perhaps as a starting point for suspicion.
    Then we have serious but well meaning confusion over what to do about the preponderance of n6 in the modern diet. Swamp it out with high dose fish oil while continuing to eat nuts (which cannot reasonably be thought by any anthropologist to be more “paleo” than legumes or wild grains) high in n-6? Turns out that might be worse than doing nothing.
    Finally we have the fatal virus that has infected paleo from the beginning but now looks more like an ineradicable retrovirus rather than a 24 hour flu. Low Carb hucksterism and offshoots of it like Krusism. The atkins fad diet -which works so well to reduce craving and food reward effects, has evolved into a full fledged dietary cult that has now, with aid of it’s profiteers selling books and xylitol based treats not found in nature, glommed on to “paleo” like Ursus Maritimus hugging a newborn penguin.
    Result – there are now people who actually believe that BANANAS can only be eaten seasonally.
    The paleo label actually is kind of finished. It does not represent any scientifically respectable approach and has such few reliable core elements as to be a heuristically useless concept. It has nothing to add to reading Michael Pollan or and just adding some red meat, or Weston Price sans sourdough bread.
    Just try being a total newbie, googling paleo diet and coming up with something really scientifically defensible beyond eating real food – you might not even get that, with all the paleo bars and supplements about.
    PS My comments are about the state of “paleo” as a meme. It is of course useful to use an ancestral approach to nutrition in some ways. The problem is, in order to instruct someone in it, I would have to specify how to do it and WHO is doing it correctly and not just making up stories, etc. And then, I would be roundly criticized for trying to constrain the libertarian wonderland that is paleo on the internet, where every idea is a beautiful snowflake that deserves a fair hearing and is somehow “contributing to the conversation” – as if dialogue about diet were a useful good for it’s own sake.
    I would be considered a “hater” who is not interested in “helping people” by being so negative as to point out which of the beautiful paleo flowers are really just weeds.”

    • Like it. Like it lots.

      It is a shame KJH didn’t keep his (mostly) sane pubic voice going. Though I can well see why he washed his hands of it all.

      His comment about now needing to instruct people to do “this paleo” and not “that paleo” are on the money. But then I see exactly the same thing in the LCHF mob… There are those recommending a LCHF (quantitative) paleo-type (qualitative) diet, and then there are those telling people to eat bread stuffing in a turkey and not the roasted sweet potato because the former is only 10% the carbs of the latter.

  10. Thank you!! This is by far the most down-to-earth, pragmatic, easily understandable definition of paleo I have read. I will be directing people to this page!

  11. really excellent post. I reviewed the acellular carbs paper 2-3 months ago and was pleased to see it being used in your analysis.
    quoting KJH back:
    “we could not have eaten easily” when we were not even who we are now, cannot be good for us. This is a conceit that has never made an iota of sense for me. other than perhaps as a starting point for suspicion.

    His use of the ‘word suspicion’ is quite funny to me – seems like he doesn’t even realise that ‘suspicion’ here is actually sound scientific skepticism with a willingness to consider not only the present and the future, but also the past. Paleo is simply another way of saying “truly scientific approach” to nutrition, movement and whatever else constitutes the study of humans interacting with their environment.

    You are doing an excellent job of an open and honest investigation into that type of study – please continue and don’t mind those who decide to muddy that approach. :D
