Labels are a cognitive double-edged sword. We need to categorize the world in order to mentally capture it – labels help us organize our mental maps of the overwhelming complexity of things and to communicate with each other. But labels can also be mental prisons, when they substitute for a thorough, nuanced, or individualized assessment – when categorization becomes pigeon-holing.
We use many labels in our writings here, out of necessity, and we try to be consistent and thoughtful in how we define the labels that we use, recognizing that any sufficiently complex category will be necessarily fuzzy around the edges. We have certainly used a great deal of electrons discussing what exactly is science-based medicine, and that the label of so-called alternative medicine is really a false category, used mainly for marketing and lobbying (hence the caveat of “so-called”).
We get accused of using some labels for propaganda purposes, particularly “antivaccinationist” (often shortened to “antivaxer”). Also “denier” or “denialist”, as in germ-theory denier. Even though we often apply labels to ourselves, no one likes having an unflattering label applied to them, and so we have frequent push-back against our use of the above terms.
As with many such terms, Read more »

Vitamins, herbs and other dietary supplements are sold as natural alternatives to pharmaceuticals and many people turn to them in an attempt to improve their health. Others seek supplements to lose weight or after hearing that they can help with serious medical conditions. These products are now used at least monthly by more than half of all Americans—and their production, marketing and sales have become a $23.7 billion industry, according to the Nutrition Business Journal.
What Are Dietary Supplements and How Are They Regulated?
98-year-old Bob Stewart, a retired podiatrist and senior Olympian, credits his use of supplements for his healthy aging. Writer Betsy McMillan, a mother of two now adult children, however, nearly suffered permanent liver damage due to a supplement that contained potentially fatal levels of niacin.
Unlike pharmaceuticals—which must be FDA-approved as safe and effective before they can be marketed—supplements are considered as foods by regulators and assumed to be safe until proven otherwise. Although pharmaceutical manufacturers face inspections to ensure that the right dose is in the right pill without dangerous contaminants, supplements do not undergo such intense government scrutiny.
Despite many reports of health problems, Read more »

There’s an old saying in medicine: “Use the new medicine while it still works.” This is more than just a cute quip. The saying encompasses a few different phenomena. When a drug is tested on a few thousand people, the luck of the draw may show a greater effect than would be seen in a larger, more diverse population. Also, less common side effects will become more evident in a larger sample. Once several million people take the drug, it may turn out that the drug isn’t as spectacular in a large, diverse population, and that certain side effects, though rare, are serious.
This is one of the reasons I’m a very conservative and skeptical physician. Today’s miracle drug may be tomorrow’s Vioxx. Less conservative doctors may make much more enthusiastic recommendations. I found one physician promoting pomegranate juice for rheumatoid arthritis (or at least linking to the article on Joe Mercola’s site without comment). It sounds harmless enough, but what’s the evidence? (You can hunt for the page yourself; I’m not linking to Mercola.)
The statement is based on a pilot study out of Israel consisting of data from six patients. The measures used seem quirky, but are irrelevant anyway. There are no conclusions that can be drawn from such a small sample. Despite this, the authors conclude (and Mercola and the doctor who posted the link presumably endorse) that, “Dietary supplementation with pomegranates may be a useful complementary strategy to attenuate clinical symptoms in RA patients.”
Really? Based on what? Read more »

There has been much abuzz about “pox parties” – the practice of parents getting a bunch of unvaccinated kids together with an infected one (pick one, really, though chicken pox is the focus of the recent article in Time) in the hope that their little sweethearts become ill and therefore “naturally” immune to the disease. This deliberate infection involves things as seemingly innocent as breathing the same air as the infected to the stomach-turning sharing of bodily fluids (Saliva lemonade, anyone?). To compound the issue, it seems that parents aren’t always taking into account how the viruses are transmitted, and end up trying oral transmission to transmit a disease that is transmitted through the air. And yes, the whole thing is as stupid as it seems.
Given that the people partaking in these events have likely not vaccinated their children against anything else, these parties could be a source point for multiple highly contagious infections. Most of us have had chicken pox as children and don’t remember it fondly – now imagine having chicken pox with mumps, mono, and maybe a little hepatitis A to top it off. It is also easy to forget in Western luxury that these innocuous childhood illnesses are actually lethal. Just measles? Well, one death per 3000 measles infections might not seem like much, until you consider the fact that in 2008, 164,000 people died of the measles worldwide – approximately the same number of civilians that have died in the entire length of the current Iraq war. That’s an annual number, and it’s gone down by almost 80% over 10 years. How? Read more »

Prince Charles is a big supporter of “natural” medicine, which in practice means unscientific and ineffective medicine. He has no particular expertise in this area, and there is absolutely no legitimate reason why he should have any influence over the practice of medicine in the UK. But he is the Prince of Wales, and he has chosen to use that celebrity to promote CAM.
Prince Charles has also recently been criticized for his credulous support for medical nonsense. The Telegraph recently reported that Simon Singh, co-author with Edzard Ernst of Trick or Treatment, and exposer of CAM pseudoscience, spoke about Prince Charles at the recent Hay Festival in India. Singh had some sharp criticism, including:
He only wants scientific evidence if it backs up his view of the natural treatment of health conditions…
We presented evidence that disputes the value of alternative medicine and despite this he hasn’t changed his mind…
Singh’s point is that Prince Charles is Read more »
