Richard, your statement brings up another weakness found in observational studies: there is a confluence of factors that could play a role in health and longevity. You say that “as Okinawans move away from Japanese yams, vegetables and fruits to more meat and processed foods that disease is increasing.” How do you know the determining factor is grass-fed organ meat when you yourself said that another factor was processed foods. Are they equal? Indeed, Okinawans have not only increased their intake of conventionally raised meat (., unhealthy product–unlike grass-fed meat and pastured eggs) and processed foods, but have also increased their intake of whole grains. Their lifestyles have also become more sedentary. More Okinawans smoke tobacco and drink alcohol than did in the 1950’s.
