If there is an antithesis to the principles of science-based medicine, it’s probably the Dr. Oz show. In this daytime television parallel universe, anecdotes are evidence. There are no incremental advances in knowledge — only medical miracles. And every episode neatly offers up three or four takeaway health nuggets that, more often than not, seem to leave the audience more ill-informed about health and medicine than they were 30 minutes earlier.
After I completed my post on Dr. Oz’s prolonged embrace of the “miracle” that is green coffee bean extract, a number of readers brought me up to speed. Green coffee beans are yesterday’s miracle. The new weight loss miracle for 2013 is red palm oil. This constant drive for miracles must keep the producers in a perpetual panic. They need at least five miracles per week. Having now watched a few episodes, I’m reminded of the classic “That Mitchell and Webb Look” skit where two nutritionists pick a new superfood. It could be just a matter of time until we see white veal profiled as a superfood in a future Dr. Oz episode.
If there is a common characteristic of complementary and alternative medicine (CAM) proponents who believe themselves to be scientific (and I include Dr. Oz in this group), it is that they extrapolate from weak clinical evidence to grandiose claims by cherry picking the most supportive strands of evidence to give the impression of being evidence-based. They have the belief, and then they look for the supporting evidence to bolster the claim. In short, to paraphrase a quote attributed to Hahns Kuhn, they use scientific evidence like a drunkard uses a light post: for support, not for illumination. As I noted with green coffee bean extract, Dr. Oz extrapolated from ambiguous, preliminary data to recommendations to consume green coffee bean extract as a weight loss strategy. Frankly, the evidence isn’t there, so I didn’t have high expectations with the latest miracle. All I knew going in about palm oil is that it’s used in most industrial food production and the demand for it is linked to massive destruction of tropical rainforests and the slaughter of orangutans. But who doesn’t want the longevity that Dr. Oz promises? So I sat down and watched another episode.
