There are many fallacies that undergird alternative medicine, which evolved into “complementary and alternative medicine” (CAM), and for which the preferred term among its advocates is now “integrative medicine,” meant to imply the “best of both worlds.” If I had to pick one fallacy that rules above all among proponents of CAM/IM, it would have to be either the naturalistic fallacy (i.e., that if it’s natural—whatever that means—it must be better) or the fallacy of antiquity (i.e., that if it’s really old, it must be better). Of course, the two fallacies are not unrelated. In the minds of CAM proponents, old is more likely to have been based on nature, and the naturalistic fallacy often correlates with the fallacy of antiquity. Basically, it’s a rejection of modernity, and from it flow the interest in herbalism, various religious practices rebranded as treatments (thousands of years ago, medicine was religion and religion was medicine—the two were more or less one and physicians were often priests as well), and the all-consuming fear of “toxins,” in which it is thought that the products of modernity are poisoning us.
Yes, there is a definite belief underlying much of CAM that technology and pharmaceuticals are automatically bad and that “natural” must be better. Flowing from that belief is the belief that people were happier and much healthier in the preindustrial, preagricultural past, that cardiovascular disease was rare or nonexistent, and that cancer was seldom heard of. Of course, it’s hard not to note that cancer and heart disease are primarily diseases of aging, and life expectancy was so much lower back in the day that a much smaller percentage of the population lived to advanced ages than is the case today. Even so, an implicit assumption among many CAM advocates is that cardiovascular disease is largely a disease of modern lifestyle and diet and that, if modern humans could somehow mimic preindustrial or, according to some, even preagricultural, lifestyles, that cardiovascular disease could be avoided. Not infrequently, evolutionary and genomic arguments are invoked, claiming that the estimated 10,000 years since the dawn of human agriculture is not a sufficiently long period of time for us to have evolved to handle diets rich in grains and meats and that we are “genetically wired” to exist on a diet like those of our paleolithic hunter-gatherer ancestors. For instance, in 2004, James H. O’Keefe Jr, MD and Loren Cordain, PhD wrote an article in the Mayo Proceedings entitled Cardiovascular Disease Resulting From a Diet and Lifestyle at Odds With Our Paleolithic Genome: How to Become a 21st-Century Hunter-Gatherer that asserted in essence, just that. Over the last decade, Cordain has become the most prominent promoter of the so-called “Paleo diet,” having written The Paleo Diet: Lose Weight and Get Healthy by Eating the Foods You Were Designed to Eat and multiple other books advocating a paleolithic-mimetic diet as the cure for what ails modern humans. Meanwhile, diets thought to reflect what our hunter-gatherer ancestors ate, such as the Paleo Diet consisting largely of animal and fish that can be hunted and fruits and vegetables that can be foraged for in the wild, have been promoted as a near-panacea for the chronic diseases of aging, such as cardiovascular disease and cancer.
But how does one determine what the prevalence of cardiovascular disease was in the ancient past? Time and the decomposition it brings are brutal on the flimsy meat of which we are made, and it is uncommon to have access to anything other than bones, much less bodies intact enough to be examined for signs of atherosclerotic disease. Even so, however, there have been indications that the idea that ancient humans didn’t suffer from atherosclerosis is a comforting myth, the most recent of which is a study published a week ago online in The Lancet by Prof. Randall C. Thompson of Saint Luke’s Mid America Heart Institute and an international team of investigators entitled Atherosclerosis across 4000 years of human history: the Horus study of four ancient populations. Basically, it was a study of 137 different mummies from four different geographic locations spanning 4,000 years. The areas spanned included ancient Egypt, ancient Peru, the Ancestral Puebloans of southwest America, and the Unangan of the Aleutian Islands.
