Alpha Brain – What’s Wrong with the Supplement Industry

There is an endless stream of supplement products on the market that are of questionable value. They tend to follow a similar pattern: put an essentially random assortment of vitamins, minerals, perhaps herbs and nutritional elements into a pill and then make whatever pseudo-health claims you want. Usually the claim is implied in the name of the product itself – sleepwell, or...

Reiki

Reiki (pronounced raykey) is a form of “energy healing,” essentially the Asian version of faith healing or laying on of hands. Practitioners believe they are transferring life energy to the patient, increasing their well-being. The practice is popular among nurses, and in fact is practiced by nurses at my own institution (Yale). From reiki.org, we get this description: Reiki is a Japanese...

Vitamins and Mortality

The discovery of various vitamins – essential micronutrients that cause disease when deficient – was one of the great advances of modern scientific medicine. This knowledge also led to several highly successful public health campaigns, such as vitamin-D supplementation to prevent rickets. Today vitamins have a deserved reputation for being an important part of overall health. However, their reputation has gone beyond...

Statistical Errors in Mainstream Journals

While we frequently on SBM target the worst abuses of science in medicine, it’s important to recognize that doing rigorous science is complex and mainstream scientists often fall short of the ideal. In fact, one of the advantages of exploring pseudoscience in medicine is developing a sensitive detector for errors in logic, method, and analysis. Many of the errors we point out...

Does Weight Matter?

Determining the net health effects of independent factors can be tricky, especially when those factors cannot be controlled for in experimental studies. For things like body mass index (BMI) we must rely on observational data and triangulate with multiple studies to isolate the contributions from BMI. But it can be done. The data, however, are likely to be complex and noisy, and...

Some Encouraging Backlash Against Nonsense

One of the themes of SBM is that modern health care should be based upon solid scientific ground. Interventions should be based on a risk vs benefit analysis using the best available scientific evidence (clinical and basic science). As an extension of this, the standard of care needs to be a science-based standard. Science is (or at least should be) objective and...

Pseudoscience Sells

It is an unfortunate truth that there is money in pseudoscience, particularly medical pseudoscience. Money both attracts charlatans and also funds their activities, which includes marketing pseudoscience and defending their claims from scientific scrutiny. In this way the game is rigged in favor of pseudoscience. With0ut effective regulation, sites like ours are forced to play whack-a-mole with the medical pseudoscience du jour....

Comparative Drug Research

The latest issue of the BMJ contains an editorial recommending that regulators (this is in the UK, but the argument applies in the US and elsewhere) should require pharmaceutical companies to provide research on direct comparison to existing therapies as part of the approval process. The authors, Sorenson, Naci, Cylus, and Mossialos, write: When a drug comes to market, evidence on the...

Acupuncture and Acoustic Waves

Here is yet another study claiming to show “how acupuncture works” when in fact it does nothing of the kind. It does, however, reveal the bias of the researchers – it is, in fact, surprising that it was published in a peer-reviewed journal. Unfortunately, the mainstream media is dutifully reporting the biased claims of the researchers without any independent verification or analysis....

Homeopathy and Plausibility

The fundamental concept of science-based medicine (SBM) is that medical practice should be based upon the best available science. This may seem obvious, but there are many important details to its application, such as the relationship between clinical and basic science. Clinical claims require clinical evidence, but clinical evidence can be tricky and is often preliminary. It is therefore helpful (I would...
