Diets and Unschooling
On the AlwaysLearning list someone had written:
Basically it rejects the whole western diet and way of eating. It calls for eating many things raw—meat, milk, seafood etc. And the list of things not to eat was mind boggling.
Joanna Murphy responded: The information you are talking about is promoted by [a particular foundation...]. We do keep these principles in mind in our diets, and I know many other unschooling families that do as well. We've actually had a small slew of minor, and a few major, complaints clear up with this stuff, and so have many others I've known.
All that being said, we all make our own choices and have lots of conversation about food. I mesh the principles in as it makes sense, being the main cook and purchaser in the house, and we work to find foods that satisfy and bring pleasure to our lives, like many families on this list do. If you are asking whether we "impose" this diet on our children, the answer is no, and that would also go for the other unschooling families that I know well enough to know that sort of thing.
Joyce Fetteroll responded: I suspect one of the immediate advantages of rawism that makes it seem like a good thing is that people consume a lot more fruits and vegetables. That *is* a good thing in terms of fiber and bulk and vitamins and minerals. You probably will feel better. But you can get that also by ... consuming more raw fruits and vegetables.
This seems to be a really good site:
Beyond Vegetarianism - transcending outdated dogmas
Lots of links to real research. On the research page is:
Research-Based Appraisals of Alternative Diet LoreComparative Anatomy and Physiology Brought Up to Date: Are humans natural frugivores/vegetarians or omnivores/faunivores?andThe rationale for vegetarianism based on similarities with apes or differences with carnivores has long been a cornerstone of the philosophy for many adherents. However, the supporting arguments have changed little for over 25 years now. Given that scientific study has advanced tremendously during that time, an update has been long overdue. This extensive tour provides an in-depth look at the numerous and intriguing problems involved, including an examination of the much more rigorous analytical techniques of recent comparative studies. Whether or not you're pleased with what the evidence points to, you're sure to come away with fascinating insights into the complex mix of factors involved in determining the diet that the human species is most naturally adapted to.

My mom just sent David a book called The 10,000 Year Explosion, by Gregory Cochran and Henry Harpending. I really like Henry Harpending's work. They've got a website up for the book: http://the10000yearexplosion.com/
Anyhow, the book is based on the idea that not only did humans not stop evolving 10,000 years ago, or 50,000 as some people posit, but that through civilization we've accelerated change through evolution. They use dogs as an example of rapid evolution. Dogs have been domesticated for roughly the same time as humans have been farming. The traits that they carry as dogs are derived from the genetic traits that a wolf has, but adapted in ways that are appropriate for their environment. So, a border-collie's hyper herding instinct is derived from wolf game-herding patterns, but is exaggerated as it was the herding that made the dog best suited to the environment of a shepherd's dog. They also point out that some wolf traits have disappeared either entirely in dogs, like regurgitating food for their puppies, or having male parental care, or traits that have disappeared in most breeds of dogs, like digging birthing dens or having a specific time of year when they go into season. The point of the comparison is to say: "[a]ny adaptation, whether physical or behavioral, that loses its utility in a new environment can be lost rapidly, especially if it has any noticeable cost. Fish in lightless cave lose their sight over a few thousand years at most—much more rapidly than it took for eyes to evolve in the first place."
So that sets the stage for the idea that the Inuit are less adapted to a farmed diet, whereas those of us who have not recently come from a hunter-gatherer or a horticulturalists society are much more adapted to these diets. They write: "There is every reason to think that early farmers developed serious health problems from this low-protein, vitamin-short, high-carbohydrate diet. Infant mortality increased, and the poor diet was likely one of the causes. You can see the mismatch between the genes and the environment in the skeletal evidence. Humans who adopted agriculture shrank: Average height dropped by almost five inches." They continue with "There are numerous signs of pathology in the bones of early agriculturalists. In the Americas, the introduction of maize led to widespread tooth decay and anemia due to iron deficiency, since maize is low in bioavailable iron. This story is not new: Many researchers have written about the health problems stemming from the advent of agriculture. Our point is that, over millennia, populations responded to these new pressures. People who had genetic variants that helped them deal with the new diet had more surviving children, and those variants spread: Farmers began to adapt to an agricultural diet. Humanity changed.
They argue that the increased incidence of diabetes among populations who have never farmed or that haven't farmed for long is a consequence of a lesser degree of adaptation to high-carbohydrate diets. It would take time to undo the changes that our changed environment has wrought, maybe the thousands of years that it takes for fish to go blind. And while we probably still have some of the genetic predispositions of our pre-agriculture forebears, more or less depending on who they were and how they subsisted, most of us are fairly well adapted to the diet of agriculture.
