Good to hear from you and many thanks for your continued support of the Paleo Diet. I hadn’t seen this piece, but I appreciate that you have brought it to my attention. It is obvious that whoever wrote this piece did not do their homework and has not read the peer review scientific papers which have examined contemporary diets based upon the Paleolithic food groups which shaped the genomes of our ancestors. Accordingly the writer’s conclusions are erroneous and misleading. I feel strongly that it is necessary to point out these errors and make this information known to a much wider audience than those reached by the readers of the U.S. News and World Report. You have my permission to syndicate my response and or your write up for the CSU Collegian to any of the major news services including AP and UPI. Additionally, I will copy a number of colleagues and scientists worldwide with this message to ensure that it will be widely circulated on the web, blogs and chat groups.

The writer of this article suggests that the Paleo Diet has only been scientifically tested in “one tiny study”. This quote is incorrect as five studies (1-7); four since 2007, have experimentally tested contemporary versions of ancestral human diets and have found them to be superior to Mediterranean diets, diabetic diets and typical western diets in regards to weight loss, cardiovascular disease risk factors and risk factors for type 2 diabetes.

The first study to experimentally test diets devoid of grains, dairy and processed foods was performed by Dr. Kerin O’Dea at the University of Melbourne and published in the Journal, Diabetes in 1984 (6). In this study Dr. O’Dea gathered together 10 middle aged Australian Aborigines who had been born in the “Outback”. They had lived their early days primarily as hunter gatherers until they had no choice but to finally settle into a rural community with access to western goods. Predictably, all ten subjects eventually became overweight and developed type 2 diabetes as they adopted western sedentary lifestyles in the community of Mowwanjum in the northern Kimberley region of Western Australia. However, inherent in their upbringing was the knowledge to live and survive in this seemingly desolate land without any of the trappings of the modern world.

Dr. O’Dea requested these 10 middle aged subjects to revert to their former lives as hunter gatherers for a seven week period. All agreed and traveled back into the isolated land from which they originated. Their daily sustenance came only from native foods that could be foraged, hunted or gathered. Instead of white bread, corn, sugar, powdered milk and canned foods, they began to eat the traditional fresh foods of their ancestral past: kangaroos, birds, crocodiles, turtles, shellfish, yams, figs, yabbies (freshwater crayfish), freshwater bream and bush honey. At the experiment’s conclusion, the results were spectacular, but not altogether unexpected given what known about Paleo diets, even then. The average weight loss in the group was 16.5 lbs; blood cholesterol dropped by 12 % and triglycerides were reduced by a whopping 72 %. Insulin and glucose metabolism became normal, and their diabetes effectively disappeared.

The author, Barbara King, has played a little loose with words and ideas here, e.g.:

Our ancestors began to eat meat in large quantities around 2 million years ago, when the first Homo forms began regular use of stone tool technology. Before that, the diet of australopithecines and their relatives was overwhelmingly plant-based, judging from clues in teeth and bones. I could argue that the more genuine “paleo” diet was vegetarian.

"Paleo" as far as diet is derived from "paleolithic", which is that portion of human development that was the "lithic" or stone age, up until the invention of much more sophisticated tools and culture, where the terms "mesolithic" and "neolithic" come into play. So a "paleo" diet would span that period of the old stoneage, which would be most of that 2 million years of meat eating Homo King acknowledges, as well as some of the australopithecines that were contemporaneous with Homo or slightly predated Homo. Thus, even though some australopithecines may have been dominantly vegetarian, they make up only a fraction of the humans (to broadly use that term) who existed during the Paleolithic. So it is incorrect to assert as King does that a "paleo diet was vegetarian."

Secondly, King's reference to a US News article on what is good nutrition is insufficient if one is really interested in good nutrition! If you go to the link she provides it is just a summary webpage with a couple of plus and minus signs and various star ratings - one might as well be looking at a movie review on rottentomatoes. One of the "minuses" in that US News page is that the paleo diet excludes "grains", but this then (as it is used in King's article) simply becomes circular logic, as the whole issue being discussed in the Paleo diet issue is whether grains are necessary to begin with.

And quite in contrast to King's assertions, our genetic material is our driving force in our eating habits. I have to supply via my food the 7 amino acids I am unable to synthesize; the components of my cells cannot synthesize these amino acids as there are no genetic instructions to do so. I also have to eat to provide various co-enzymes ("vitamins") and such, all of which are precisely determined by my genetic makeup. King's dismissal of the primary role our genes make is disturbing.

Certainly people are prone to making diets magic, and there is a swamp of magical thinking that surrounds dieting (including the paleo-dieters), but King's article is not a very good discussion of the real issues at hand. The worst thing that can be said about the paleo-diet is that it is ecologically unsustainable for 7+ billion people in the world, an issue King doesn't really address.
