In a recent post, I observed that “Anyone with a university education ought to be able to recognise the limits of their own expertise, and to be able to distinguish between bogus sources of information and the products of genuine peer-reviewed research.” Sadly, the ABC’s Catalyst program appears to be failing that test, judging from the first episode of their report, attempting a debunking of the claims that elevated cholesterol causes heart disease, and that statins reduce the risk of disease. I looked at the evidence on this when I started taking statins around 20 years ago, and it seemed pretty convincing. In the last few years, with intensive exercise, I’ve reduced my cholesterol and stopped taking medication, so I think I can look at this fairly objectively.
As I said, before regarding someone’s opinion as having weight, you need to check whether they have any reason for claiming authority. A quick visit to Google reveals the following info on the medical “scientists” quoted in the program
*”Stephen T. Sinatra is a board certified cardiologist, nutritionist, and anti-aging specialist specializing in integrative medicine. He is also a certified bioenergetic psychotherapist”
* Jonny Bowden – The Rogue Nutritionist is a weight loss coach
* Michael Eades is the biggest prat in the diet industry (alert: possibly not a neutral source).
* Ernest Curtis publishes not in medical journals but on LewRockwell.com
AFAICT, none of them has ever published scientific research in a peer-reviewed journal (still need to check this more carefully). I’m going to watch Part II now. But based on Part I, I’d say everyone involved should hand back their degrees.
Update The second episode was an improvement on the first. At least it quoted real scientists who have done actual research, and provided something like links to the real stuff (not sure if that will show up in transcript). And the general problems of research funded by drug companies are real enough. OTOH, at least one of the experts quoted against statins was described as a litigation expert, which suggests that the bad incentives aren’t all on one side. An interview with someone from the Heart Foundation was a welcome element of balance, but looked to me to have been edited in a way that gave a misleading picture of what (I imagine) was actually said.
Moreover, given the stress on drug company profits, the show might have taken a minute to point out that both simvastatin (Zocor) and atorvastatin (Lipitor) are now off-patent. There’s been some dispute over whether Australia has moved fast enough to cut the price paid for Lipitor and to encourage the prescribing of cheap generic versions, but the days of statins as a cash cow are already receding. That doesn’t preclude the possibility that its advocates are locked into positions taken previously, but it does cast some doubt on the continuing relevance of financial incentives.
fn1. As I grow tired of pointing out to people who have a misunderstood high school lessons in logic, the alternative to rejecting unqualified “experts” out of hand is not to look at the evidence they present and “make up your own mind”. It’s to undertake the years of intensive study needed to master the subject, then assess the evidence and make up your own mind.
