I had a great time at the Ancestral Health Symposium this weekend. Despite being an incredibly busy conference, I was thankfully able to meet a lot of the people involved with the evolutionary health and fitness community. If we didn’t get a chance to meet up, I apologize and hope that maybe we can at some point again in the future.

For your benefit, I’m reposting a summary of the Twitter posts I sent out during the symposium. In them, I think I’ve captured some of the salient points derived from the talks that I attended (I tried to attend as many as possible). Feel free to discuss the topics below, I’d like to hear what you think.


Dr. Loren Cordain

  • Surprisingly, U.S. per capita consumption of sugar has decreased slightly in the recent years, still super high.
  • Meta-analyses show that vegans and vegetarians on average don’t do any better health-wise than the average meat eater.

Dr. S. Boyd Eaton

  • The average American gets 13% of their nutrient intake from fruits and vegetables. It was more like 50% for hunter-gatherers.
  • During the paleolithic, male and female equality was greater than anytime since.

Melissa McEwen

  • Fermented foods could potentially be a replacement or supplement for colonic fermentation, improving food quality.
  • Human bacterial microbiome evolving very rapidly even as human change less dramatic – affects digestion/immunity.

Dr. Matt Metzgar

  • 2001 total estimated negative externalities from U.S. agriculture can be estimated to $3.8 billion – think pollution, soil erosion, etc.

Denise Minger

  • Many popular vegan doctor health programs (like Ornish) work not for lack of meat, but for removing junk sugar processed food crap.

Dr. Kevin Boyd and Dr. Michael Mew

  • Diet isn’t the only culprit in poor jaw and teeth development, mandibular muscle usage shapes the growing face.
  • Use it or lose it, the massive modern reduction in masticatory effort is maladaptive for jaw development.
  • From a broad perspective, only about 1/3 of the U.S. population has normal occlusion (jaw/teeth structure).
  • Bottles do not promote proper palate formation in babies like breast feeding does.
  • Human faces are shrinking. They don’t grow to the same size as before 10,000 years ago due to easily chewed processed food diets.
  • HFCS and sucrose are not the same, there is a difference in the chemical bond structures.
  • The tongue and inner palate apply pressure to cranial facial complex at an early age causing the rest of the skull to grow.
  • Cavities (tooth decay) are on the rise in children in the US for the first time in decades.

Tucker Max

  • What’s missing from our ancestral health studies? “violence”.
  • The noble savage theory of hunter-gatherer utopia is “bullshit”.
  • Fighting (MMA) allows you to test yourself on an anvil of truth which you can’t find anywhere else in society.

Dr. Seth Roberts

  • Added butter to diet and saw measurable increases in the ability to perform random timed arithmetic problems.
  • Performed self experiments for balance and memory while on supplemental flaxseed oil and found clear improvements with use.
  • Great advice: brief daily mental tests can help us decide what to eat. Try some home experiments.

Chris Masterjohn

  • Degeneration of lipoprotein molecules due to inflammation and oxidation is a more compelling explanation for cardiovascular disease than the standard lipid hypothesis or the cholesterol-heart hypothesis.
  • Fruit and vegetable polyphenols probably promote antioxidant behavior by being slightly toxic and stimulating glutathione production.

Dr. Michael Eades

  • How do we know what early humans ate? The stable nitrogen-15 isotopes in fossils put them along side other carnivores.
  • Discussed this article by Gary Taubes on restricted carbs and weight loss, emphasizing that low fat diets are really low carb diets – http://www.garytaubes.com/2010/12/calories-fat-or-carbohydrates/

Jamie Scott

  • Many countries see stress as a major workplace health problem but most companies invest in cheaper solutions like flu vaccines rather than more useful stress management programs.

Dr. Emily Deans

  • Recipe for a resilient brain: eat a diet low in food toxins, which promotes a happy gut, and keeps immune system strong to fight or avoid infection.

Dr. Lynda Frassetto

  • Fruit and vegetables reduce the acidity of your food intake because they contain compounds which are broken down into bicarbonate.
  • Salt sensitive people (genetic component) tend to be more insulin resistent on average. More salt, more insulin.

Don Matesz

  • Non-nutritive ingestive behaviors are common in mammals most likely to balance energy input with output – think herbs, spices, tea.

Vivian Shelton

  • In the US obese people spend $1,500 more each year on average for personal health costs.

    Re: Drs Boyd and Mew –> “HFCS and sucrose are not the same, there is a difference in the chemical bond structures.” Perhaps, but I’m more interested in the the body’s reaction to ingestion of these. Biologically, does the body treat ingestion of these differently?

    • David Csonka says:

      Mark,

      That was the implication, that the body treats them differently. Unfortunately I was not able to ask questions of them to qualify the statement.

    I followed the #AHS11 hash tag ever so closely all weekend long. It was great to see a wealth of information pouring out of the Paleo community. Seems like you had a good time!

  4. Jason says:

    I picked up on that Cordain sugar stat as well. I would like to know what the U.S. per capita consumption of artificial sweeteners is. That would be an interesting comparison.
    I enjoyed the Mat Lalonde talk. It could be summed up as “there are many things you don’t know, so watch what you say.”

  5. Mark - Indy says:

    Have they determined the location for AHS12? Will it again be in L.A.?

  6. Thanks for this summary, David. Well done. I’m looking forward to AHS ’12!

    Thanks for this! I’m so envious of everyone who got to go. Though I’m fairly sure I’d loath him in real life, I always get a kick out of Tucker Max’s comments (his Celeb Nerdy interview is one of the best summaries of paleo around).

    • David Csonka says:

      He seemed like a cool guy. I introduced myself and he chatted me up for a bit even though I was a complete stranger. He even helped extricate me from a terrible social blunder when talking to somebody else in his group. OK guy in my book

      • Sid says:

        Nice to hear something positive about him. He’s obviously very smart – I adore anyone who can be articulate while swearing :)

  13. Kevin Boyd says:

    per my statement that HFCS and sucrose are molecularly different: Sucrose(table sugar) is a DIsaccharide that exists only in the precise 50-50 chemically-bound form of (equal amounts of) 2 different MONOsaccharides, glucose and fructose; HFCS is not a disaccharide, rather, it is a monosaccharide mixture of free/unbound glucose and fructose molecules. Furthermore, ratios of industrial/commercial HFCS mixtures consist of higher amounts of fructose molecules than glucose molecules. The primary health implication for the molecular dissimilarity between the 2 sweeteners is noteworthy: humans lack the enzymatic hardware necessary for utilizing fructose as a “readily-available” energy substrate….and, as it can only can be metabolized in the liver, and once there, unless there is a huge demand for glycogen replenishment (i.e., starvation, elite athleticism, etc.) it is converted into fat (de novo lipogenesis)…and in the process, also causes phosphate depletion and uric acid buildup; in nature fructose is ALWAYS bound to fiber (i.e., we are not genomically equipped to cope with large amounts of free/unbound fructose…..watch Rob Lustig’s UCSF YouTube video:”Sugar:The Bitter Truth” for further clarification, and please feel free to email me (kbo569@gmail.com) if further questions.

    Thanks

    • David Csonka says:

      Thank you for the clarification Dr. Boyd! I thoroughly enjoyed the presentation made by you and Dr. Mew at the Ancestral Health Symposium. As somebody with a poorly aligned set of teeth, it was especially interesting to me.
