…but maybe you have.
If so, click over to Science-Based Medicine for Dr. Harriet Hall’s thoughts on them and Staffan Lindeberg’s seminal nutrition study. This is her second recent post on ancestral diets (aka paleo). A snippet:
I am always suspicious of initial reports of unusually healthy or long-lived groups in remote areas, because I have so often seen such reports disconfirmed by subsequent investigations. Lindeberg’s studies were done in the early 90’s and have not been confirmed by other studies in the ensuing two decades. In the Kitava study, the ages of subjects were not objectively verifiable, but were estimated from whether or not they remembered significant historical events. The absence of heart disease and stroke was deduced by asking islanders if they had never known anyone who had the symptoms of either condition. This was reinforced by anecdotal reports from doctors who said that they didn’t see those diseases in islanders. EKGs were done on the Kitavans, but a normal EKG does not rule out atherosclerosis or cardiovascular disease. I’m not convinced that we have enough solid data to rule out the presence of cardiovascular disease or other so-called “diseases of civilization” in that population.
You can guess where this is going.
Dr. Stephan Guyenet chimes in with cogent comments.
