Editor’s note: This post is a collaborative effort between Grant Ritchey, a Science-Based Medicine semi-regular, and Stephanie Tornberg-Belanger, a co-author of the research paper discussed below and who brought the study to Grant’s attention. We are pleased to welcome Stephanie as a guest contributor to SBM.
That amazing coconut oil! What can’t it do?
In his last SBM post, Grant reported on a systematic review of the literature that undermined just about everything dentists had been taught in dental school and have been preaching to patients since The Olden Times: flossing, as it turns out, is not the be-all, end-all that we’ve been led to believe with regard to cavity and gum disease prevention. While the message itself was interesting and relevant, the meta-message in that piece is that we all must be willing to slay our own sacred cows when the evidence demands it, even if it requires shedding long-held, cherished beliefs. This is difficult for any human being to do, and skeptics who are presumably open minded are no different (and can sometimes be worse, because we are often overconfidently convinced of our “rightness”).
So with that in mind, gather ’round children, because we have another meta-message for you. This one deals with coconut oil.

This is not a health food. Don’t drink it.
I enjoy feedback from readers. Yes, there’s the regular hate mail accusing me of being a Big Pharma Shill. But there’s the occasional appreciative comment from someone that found a post helpful or informative. The most gratifying feedback is when someone tells me that something I wrote led to a more informed health decision. Often it’s because I was able to answer a question that they couldn’t find a science-based answer to. I’ve answered thousands of questions in my pharmacy career, and have only blogged a handful of them (so far). One of my most fascinating experiences was a stint working evenings in a pharmacy that happened to have a large “natural” health focus. It’s there I began to scrutinize alternative medicine more closely, because it was virtually all the store sold. Homeopathy, ear candles, copper bracelets and salt lamps were all for sale. If it was unproven, proven ineffective, or defied some law of physics or chemistry, this pharmacy probably sold it. But the customers loved these products. I was dumbfounded. Some would buy dozens of supplements, costing hundreds dollars per month, on the advice of their naturopath, treating some vague or non-specific complaints. Others swore by homeopathic remedies, for themselves and their pets. It was common to meet people who were treating conditions that either didn’t exist, or hadn’t been properly diagnosed, like naturopath-diagnosed “food intolerances” or “hormone imbalances”. There were also the occasional “pH balancing” advocates that insisted I was misguided and uneducated for reassuring them that their body’s pH was just fine, despite what their urine test strips were telling them.

Candida albicans growing in a petri dish.
Savvy consumers have learned over the years that the primary goal of marketing is to create demand for a product or service. This has risen to the point of inventing problems that do not really exist just to sell a product that addresses the fake problem. Who knew that my social status could be destroyed by spotty glassware.
Better yet, if you can make people worry about a nonexistent problem, something that they were not previously aware of and don’t understand, they might buy your solution just to relieve their worry.
This type of “artificial demand” marketing can be very insidious when it occurs with medical products and services. The pharmaceutical industry has been accused of generating artificial demand for some of their drugs. For example, osteopenia is a relative decrease in bone density, but not enough to qualify for osteoporosis. Osteopenia is not really a disease, or even necessarily a mild version of osteoporosis, although it is a risk factor. Merck, however, was happy to broaden the market for its drug for osteoporosis and argue that patients with osteopenia should be treated also, even though the evidence really did not support this.
Sometimes the accusations are flat-out wrong. GSK has been accused of inventing restless leg syndrome (RLS) to sell a failed Parkinson’s drug. In fact the drugs used for RLS are successful Parkinson’s drugs. Further, I found references to RLS in neurology texts going back over 50 years, and there were even older references although not using the same name.
