PaleoVegan say it’s curtains for the Expensive Tissue Hypothesis; Carolyn jams out on sociobiology and violence

November 29, 2011

This is worth a re-post. Once again the brilliant pre-frontal cortex over at PaleoVeganology has done some wonderful reporting and analysis. This time it is regarding a new study that appears to put the Expensive Tissue Hypothesis to rest once and for all. He also discusses, among other things, the history of this hypothesis and how it was never meant to encompass such simplicities as “meat made us smart” or “meat made us human”. Alas, as ideologies compete to be representative of the most “natural” and therefore most “normal” and “necessary” way to be, many paleodieters and other carnists have relied heavily on this hypothesis for their arguments.

But as we leave ETH’s funeral, we shouldn’t just clap our hands and embody everything we argue against by saying, “SEE? It’s NATURAL to be vegan! Science has proved it!” That’s not what this is about. Rather, the way that the ETH has been used by carnists represents a phenomenon: Our unwillingness to accept responsibility for our choices, or to even admit that we have choices. This Normal, Natural, Necessary brand of logic has been used to uphold almost every type of unnecessary violence in human history, and pseudo-science has often accompanied it. We’ve written about this extensively elsewhere in our blog including here, here and here. Science is wonderful and liberating when it’s used how it’s supposed to be used (as Paleovegan uses it): as a method; as a critical thinking tool, as a path by which to ask questions, open doors, admit we’re wrong, assess, reassess, make connections, get awestruck, and hopefully figure out a thing or two in the process. But leaving our complicated social and psychological choices to vague arguments about “nature” and cherry-picked data isn’t science; it amounts to little more than sociobiology, rationalization, and dangerously lazy thinking.

We don’t need to say “veganism is natural” or “meat eating is not natural” in order to make good arguments for veganism; if we do that, we are falling prey to dangerous and convenient sociobiological arguments. Sociobiology is the study of the “biological sources of social behavior.” And sociobiology should always be questioned, for it has generally not amounted to much more than biological determinism. It is the editorializing of science. It is taking objective biological facts and assuming that certain subjective behaviors can and do extend from them. From there, there’s usually some kind of sticky, subtle moral leap: This ancestor ate meat, so we should too, in fact we’re stupid if we don’t. Men are bigger than women, and women are reproductive machines, so that’s why men rape. Animals kill each other, so it’s natural for us to be at war, and we’ll never not be at war because we are just naturally aggressive.  Homosexuality is an aberration because it doesn’t lead to reproduction (OR homosexuality is evolutionarily smart because it staves off overpopulation… how about homosexuals just exist because they love each other?) Women have smaller brains, so of course they’re not as intelligent. There’s a scientific explanation for everything, right?? But many people believe that sociobiology is little more than racism, sexism, and other violence wearing science’s clothes.

In short, we should carefully distinguish between science and sociobiology, and the latter should, if not scare the pants off anybody who wants to change the world, at least make them really weary.

Now, here’s some actual science: Humans have big brains relative to other species, and in particular, a big frontal cortex. When you have the kind of frontal cortex a human does you are able to make all kinds of complicated assessments and choices. And here’s my wish, given that fact: Let’s work with what we have, and celebrate our ability to make conscious choices, and our ability to do the least harm…and let’s stop worrying so much about which of our ancestors ate what and who and when. While we’re at it, let’s stop worrying about a gold-standard perfect diet and, by extension, perfect health and immortality, because those things don’t exist, and never have.

Anyways, the historical truth about food, as usual, is messy; some humans ate some types of meat at some point, others ate other things, and there are a thousand scenarios, motivations, and ecologies to be accounted for. But even if there were one answer as to what our paleolithic ancestors ate, it would be irrelevant. Because we are not paleolithic. Because we have to worry about ourselves, now. Today. 7 billion humans, industrialization, capitalism, ecocide, 2011, hundreds of billions of unnecessary nonhuman deaths, constant war. And, among other things, a whole bunch of us who deny that we are regularly making choices–not just being whipped around by some mysteriously undefined inkling called, conveniently, “nature”. Like it or not, this is what we’re working with. Let’s be present with our situation instead of copping out by slipping into simplistic, irrelevant, and ultimately impossible fantasy re-creations of the past.

Notes on meat-capitalism, paleofantasies, & Keith’s weird feminism re: chapter 4 resource analysis

July 23, 2010

Before we continue, some food for thought about our initial chapter 4 resource analysis…

1. Consider the connections between this low-carb, high-meat craze, how much money is made by the kinds of “brand” diets– capitalist business ventures–Keith is referencing, and how meat industries (including “humane farms”) stand to profit from it. Since only about 3.2% of people in the US are vegetarians, and 0.5% are vegans, we’re assuming this question about capitalism and ulterior motives does not pervade the public conversation re: plant-based diets the way it does re: the meat conversation.

2. A lot of the dietary “facts” Keith offers in this chapter, are based in assumptions related directly and indirectly to some kind of “paleo” diet, which Keith assumes (erroneously, if we look back at this article which takes us through the first-hand, peer reviewed sources Keith makes claims on but apparently hasn’t read) is based largely on meat. There is actually very little objective information about the diets our ancestors ate. The evidence we’ve found can only be speculated upon based on best guesses. This is the nature of paleontology– it’s the study of incomplete evidence. It’s an easy science to use, alongside evolution theory, if you’re trying to justify ideology. (Also see discussions here and here about how using the 3Ns– natural, normal, and necessary– is a classic way to couch bias and ideology.)

This New York Times article is worth reading: Evolutionary biologist Marlene Zuk makes some valuable points about different “paleofantasies”– nostalgia for a non-existent time when humans ate a diet somehow “perfectly” suited to them. Some of her thoughts:

“In short, we have what the anthropologist Leslie Aiello called ‘paleofantasies.’ She was referring to stories about human evolution based on limited fossil evidence, but the term applies just as well to nostalgia for the very old days as a touchstone for the way life is supposed to be and why it sometimes feels so out of balance…The notion that there was a time of perfect adaptation, from which we’ve now deviated, is a caricature of the way evolution works.”

“How much of the diet during our idyllic hunter-gatherer past was meat, and what kind of plants and animals were used, varied widely in time and space. Inuits had different diets from Australian aboriginals or Neotropical forest dwellers. And we know little about the details of early family structure and other aspects of behavior. So the argument that we are “meant” to eat a certain proportion of meat, say, is highly questionable. Which of our human ancestors are we using as models?”

This article by Greg Downey builds on Zuk’s and makes some interesting points. That the “perfect” or “noble” savage had a diet “perfectly” in line with nature is, according to Downey, “an adaptionist fantasy”. He states: “Zuk draws on Leslie Aiello’s concept of ‘paleofantasies,’ stories about our past spun from thin evidence, to label the nostalgia some people seem to express for prehistoric conditions that they see as somehow healthier. In my research on sports and masculinity, I frequently see paleofantasies come up around fight sports, the idea that, before civilization hemmed us in and blunted our instincts, we would just punch each other if we got angry, and somehow this was healthier, freer and more natural (the problems with this view being so many that I refuse to even begin to enumerate them). It’s an odd inversion on the usual Myth of Progress, the idea that things always get better and better; instead, paleofantasies are a kind of long range projection of Grumpy Old Man Syndrome (‘Things were so much better in MY day…’), spinning fantasies of ‘life before’ everything we have built up around us… So before we start waxing nostalgic about all the health benefits of a Pleistocene diet, perhaps we should remember that our ancestors’ food often came in this nasty packaging which tended to run away, attack them, or just go missing entirely when they were really hungry.”

3. It’s noteworthy, and upsetting, that Keith– supposedly a radical feminist– keeps citing from authors who are in some way proponents of fad diets, weight training, getting thin, anti-aging therapies, etc. We are radicals who see the intersections between animal rights and feminism, and we don’t trust things that come out of the mainstream “diet” industry, or support things that play a role in women hating the way they look. We thought Keith– veganism aside–supported women in this way, too. Why in the world is she giving so much credence and attention to these resources? And how, after all this, does she have the nerve, in other chapters, to a) simplistically critique vegans as eating disordered and b) conveniently reference Naomi Woolf’s The Beauty Myth, a groundbreaking and highly regarded deconstruction of the misogynist diet and beauty industry? For all of the energy she puts towards proclaiming all vegans as anorexics, she conveniently fails to discuss the connections between anorexia and low-carb, high-meat fad diets (whether it’s the atkins, the paleo, the south beach, or any other play on this theme), as well as the connections between low-carb diets, fad diets, long-term lack of satiety, and how this can incite bingeing and purging.

Not to harp on it, but this is doubly infuriating, since Keith and many of her positive reviewers (see “beg” us (see chapter one) to just trust her and give her the benefit of the doubt as a seasoned radical. We thought this was supposed to be a book about radical ecology, agriculture, vegetarianism, and meat-eating. What we find, instead, is a book that is subtly based upon– indeed, permeated with–information from quick-fix diet cures that prey on insecure people, brand-name diets with profit motives, and Atkins-style/”paleo” diet fads that help the both the meat and the woman-hating diet industries profit… and are, by a preponderance of the most reliable medical evidence avaliable, definitley unbalanced and most likely unhealthy in the long-term. All of this is couched in passionate–and patronizing– language about compassion, ecology, liberation, and the ignorance of vegans. She even says “duh” more than once in this book. Throw is kas-laamal, the idea she uses to state that vegans think like children, and it’s really hard to not envision Keith as a domineering, mocking, and psychologically abusive mother.

Chapter 4 resource analysis…

July 22, 2010


Of the 288 citations in chapter 4…

-28 (10%) are from the pop-science, brand-based book The Protein Power Life Plan by Eades & Eades. This book generally talks about low-carb diets like the Atkins. At least they are doctors. But here are some thoughts about this diet and similar diets, from other doctors:

WebMD, a conglomeration of different doctors,views the Protein Power Life Plan, as the authors seem to as well, as one which is largely useful for short-term weight loss. (See Keith’s many discussions in this book about how veganism basically equals anorexia, and feel free to scratch your heads like we did.) They also say that in the long-term, it can be “seriously deficient in important nutrients”. Bonne Brehm, Ph.d and nutrition scientist, writes: “In the short term, the low-carb diets are effective — we see weight loss, improvement in some metabolic functions such as blood pressure, loss of body fat, but their real hazard is that they are nutritionally poor,” she says. “They are low in calcium, low in vitamins C and A, low in fiber. We don’t know if taking a vitamin-mineral supplement is adequate. There are a lot of micronutrients in foods that are not in supplements, including some we don’t even know about yet. We do not have any long-term studies on these alternative diets with the extreme modifications of a nutritionally balanced diet.”

Famed vegan doctor and researcher Michael Gregor is the author of Carbophobia: The Scary Truth About America’s Low-Carb Craze, which you can read for free here. Here, you can also read about how the ADA, AMA, The American Cancer Society, The American Kidney Fund, and The American Heart Association have been warning about the health risks of low-carb, high protein diets for years. Etc.Make of this what you will. Dr. Gregor, in his aforementioned book, also talks about how the Atkins and other high-protein diets have directly profited the meat industries, while dismissing wide-ranging evidence that these types of diets are ultimately unhealthy. Then the Atkins Corporation threatened to sue him because, essentially, he was challenging this low-carb, high-meat industry.

-41 citations are from the book controversial book Good Calories, Bad Calories by Gary Taubs who, although he has studied physics and aerospace engineering, is also not a nutritionist or medical doctor. This book is also largely about obesity, dieting, and its relation to low-carb, high-protein diets. See above for other opinions about this diet craze. 6 more citations are from Taubs’ article “What If It’s All Been A Lie?”, so Taubs makes up 16% of Keith’s citations.

-12 citations (4%) are from Sally Fallon’s Nourishing Traditions cookbook. Sally Fallon, like Keith, is also not a nutritionist, doctor, biologist, or trained in any health traditions. She is a “nutrition researcher” with two college degrees in English, who wrote a cookbook. This book has been criticized in similar ways to Keith’s: “While Nourishing Traditions has over 200 references, many are antiquated, with poor observations. For the most part, the authors reference their own articles and those of other Weston A. Price foundation authors. Only fourteen of the references are from peer-reviewed journals published in the last ten years, and for most of those fourteen, the authors misrepresented what was stated in the articles.” This critique goes on: “Nourishing Traditions… is a smorgasbord of woefully outdated and potential dangerous advice. For example, ‘If you cannot get your family to eat organ meats whens served as such, there are plenty of ways to add them to their foods without their knowledge… Poached brains can be ground up and added to any ground meat dish, as can grated raw liver.’ Even if it were not so clearly known that animal products in general need to be strictly limited in the diet, common sense should tell us not to eat the brains of animals in light of what is now known about mad cow diease and its human equivalent, Cruetzfelt-Jakob disease… Fallon and Enig perpetuate long-held  nutritional myths by referencing the same people who started the myths in the first place.”

-18 citations (6%) are from The Untold Story of Milk by nautropath Ron Schmid. Our friend (see above) Sally Fallon says this is a “fascinating and compelling book”. They publish on the same press. Actually, it is unclear whether or not Sally Fallon has something to do with the publishing and/or editing at New Trends Publishing. Let us know if you figure it out. There are 4 citations from another of his books, Native Nutrition, so that’s 20 citations (7%) from this author. We also feel the need to point out that this Schmid has a brand of various “formulas”, beauty products, anti-aging products, and other things he sells based on his ideas. Look, his shampoo only costs $17.

-32 (11%) citations are from the controversial Against the Grain by Richard Manning, who is a seemingly well-regarded investigative and environmental journalist but also not a doctor, nutritionist, or anthropologist of any kind.

-28 citations (10%) are from The Whole Story of Soy by Kaayla Daniels, who has a Ph.D in nutritional science and “anti-aging therapies”. She has never published a scientific paper. Furthermore, this book has been criticized as a pseudo-scientific–at best– rant that basically serves to uphold the theories of our friends, Sally Fallon and the rest of the Weston A. Price Foundation. In fact, Fallon is the editor of this book (see here, for instance). This org has what many consider to be an unreasonable and unsubstantiated bias against soy. And here’s an interesting review that breaks down the misinformation in Daniel’s book. And believe it or not, not all vegans eat soy or are ignorant to potential problems of soy (see our resources page for info about soy-free veganism), nor is everybody who eats soy a vegan. So even if it were a vaguely reliable source, this book only relates directly to veganism by a dishonest intellectual stretch. Keith cites it anyway in her case against veganism– 28 times.

-26 citations (9.7 %) are from The Great Cholesterol Con: Why Everything You’ve Been Told About Cholesterol, Diet and Heart Disease Is Wrong! by unabashed anti-vegan, Anothony Colpo. Colpo is an “independent researcher” and weight trainer and his controversial book is basically about what the subtitle title says. A lot of people seem to think he’s a bit off his rocker. Check out some of the posts he’s made about people who disagree with him, including Keith’s off-cited Eades and Eades. We don’t want to get our health information from someone whose only expertise is in weight training, who has not even the smallest bit of training in medicine or how to interpret the technical language of scientific articles. You decide for yourself.

-4 citations (2%) come from another book called The Great Cholesterol Con, by Dr. Malcolm Kendrick. This seemingly intelligent and in-depth review states:“Although it makes a number of excellent serious points, readers with a background in the relevant science might also laugh at some of the egregious scientific errors in the book and some of Kendrick’s poorly conceived speculations – or at least find themselves scratching their heads.” Again, you decide. Do your own research. Compare Kendrick and Colpo against thousands of peer-reviewed studies about cholesterol.

-11 citations (4%) are from an internet article by Ben Balzer that has no citations or references listed!!! The article is about his book, which also seems to be a brand, The Paleo Diet. Ben Balzer is a family physician, but he is not an anthropologist, paleontologist, or biologist. He even gives a disclaimer about his book on his own blog. When I googled Ben Balzer + the name of this article, the only thing that came up was it and a link to Lierre Keith’s website.


-13 citations (5%) are from two books by Julia Ross, The Mood Cure and The Diet Cure. Ross has an MA in clinical psychology and an MFT (masters in family therapy.) So, though not a psychologist (as that requires having a Ph.D and years of research experience, as opposed to clinical psychotherapy training), we’re sure she knows a lot about psychotherapy and mental illness. However, she is not a nutritionist or doctor. Her two books also seem to be some kind of brand. The Diet Cure website tells us, Here you can learn which of the eight key physical indicators is causing your particular problems and get an idea of how to use the book to correct them in 24 hours…You’re also in the right place for an image adjustment. You’ll find the healthy, sensual, immortal beauty of Venus throughout the site. Contrasted with her opposite, she is here as a reminder that a healthy body image is an important part of your Diet Cure.” No thanks, Julia.


The preceding citations comprise 80 percent of Keith’s “substantiating evidence” in this 105-page chapter… a chapter that supposedly makes scientific claims about health, carnism, and veganism, in a book that supposedly does the same. All of these resources are non-scientific or pseudo-scientific; not one is from an academic or peer-reviewed journal. For Keith, they are second-, third-, and fourth-hand sources. At least one of them has no references at all!

At least three of the authors– 20% of citations– are directly involved with the Weston A. Price Foundation, a controversial anti-vegan group. It is noted for its pro-meat, pro-animal fat diet, pro-raw meat and dairy regimen that runs completely counter to, and has been debunked by a preponderance of, modern medical evidence (again, a diet similar to those of the “paleo” and Atkins genres). It’s noted, also, for its zealotry, its intolerance and mockery for views and research that differ from its own, its constant referencing of its own members as “proof” of its theories, and its misrepresentation of the complicated and extensive work of Weston Price. See this resource or some of the above-linked articles regarding this. Or, get a copy of a book or two by these authors and skim through it. On the very cover of Fallon’s cookbook, for instance, it is dismissed as “politically correct” and “dictatorial” to talk about cholesterol concerns.  Many people believe that the hype about soy products being bad for you goes back almost entirely to this organization’s campaign against it.

Even the claims that come from people who have an academic background are written in a journalistic, editorial style, and/or are written about an subject they didn’t study in academia. And most of the information here is from books whose content is about what many people, both lay-people and scientists, consider, at best, silly and counter-intuitive, and, at worst, highly dangerous. Several of these authors are, in fact, marketing “diet brands” for their own profit. Many of the use manipulative, mocking language to suggest that if you disagree with them, you are being aggressive or naive. Perhaps this is where Keith gets her tone from.

We have a lot more to look at in chapter 4, including the remaining 20 percent of citations, a select few of which are peer-reviewed journal articles, as well as the particular ways in which Keith interprets and uses her references. Keep checking back.
