Hi Wally, I have a great deal of respect for Dr. Cordain and his work. I am particularly impressed with his work on cereal grains. That said, there are a number of stark examples where pre-conceived notions, based on scientific principles and findings, just did not stand up when put to the test in humans. Stefansson and Andersen's one-year trial of an all meat diet comes immediately to mind. Given the principles of human nutrition, then and now, the medical pundits were sure that both subjects would become very sick on an all meat diet. Yet they didn't. Similarly, Elaine Morgan, in "The Scars of Evolution," describes the scientific evidence proffered to refute the aquatic ape theory. Someone immersed in arctic waters should only last a matter of a few minutes before succumbing to hypothermia and then cardiac arrest due to cooling of core body temperature. Yet Morgan points to Lynn Cox who swam from Alaska to the USSR, in 1987, in those frigid waters at temperatures of 3 to 7 degrees Centigrade, without lanolin coating or a wet suit, and survived. In theory, because of heat losses, she could not have survived. But she did. There are many more such stories. My point is that anecdotal reports or clinical trials can tell me what real people experience - such as the Inuit who had robust bones until they started eating European foods. Theories about how the Inuit diet would destroy our bones just don't mean very much in the face of clear evidence that the theory just isn't true. I understand that Cordain is doing the best he can in a difficult situation, but some of the conclusions he draws just don't stand up to scrutiny - such as the current issue under discussion/debate. I also disagree with your idea that Cordain's approach is more scientific than anecdotal reports. An integral part of the scientific method is observation. With anecdotal reports, assuming they are accurate, we have a single observation. Such single observations have traditionally been the starting point for many scientific discoveries.

Hi Ron. I think one knock against Cordain is that he is essentially a researcher and statistician, and not a clinician. He gathers research from all over, and then makes conclusions based on statistical analysis. Some would say this is a bad approach. Others would argue that, considering the nature of the beast (cave-diet in a modern world), he is doing the best he can under the circumstances. I would argue that his research methods are a bit more scientific than anecdotal methods, and a bit less scientific than clinical trials.=
