According to naturopathy, any and all of these could be medicine.  According to science...not so much.

The deceptive rebranding of aspects of science-based medicine as “alternative” by naturopaths continues apace

That naturopathy is a veritable cornucopia of quackery mixed with the odd sensible, science-based suggestion here and there is not in doubt, at least not to supporters of science-based medicine (SBM). However, what naturopaths are very good at doing is representing their pseudoscience as somehow being scientific and thus on par with conventional SBM. So how do they accomplish this? Certainly, it’s...

GAPS Diet

A correspondent asked me to look into the GAPS diet.  I did. I was sorry: it was a painful experience. What a mishmash of half-truths, pseudoscience, imagination, and untested claims! GAPS stands for Gut and Psychology Syndrome. It is the invention of Dr. Natasha Campbell-McBride. According to her, a wide variety of health problems can be traced to a single cause: an imbalance...

It’s a part of my paleo fantasy, it’s a part of my paleo dream

There are many fallacies that undergird alternative medicine, which evolved into “complementary and alternative medicine” (CAM), and for which the preferred term among its advocates is now “integrative medicine,” meant to imply the “best of both worlds.” If I had to pick one fallacy that rules above all among proponents of CAM/IM, it would have to be either the naturalistic fallacy (i.e.,...

Calcium supplements and heart attacks: More data, more questions

Why take a drug, herb or any other supplement? It’s usually because we believe the substance will do something desirable, and that we’re doing more good than harm. To be truly rational we’d carefully evaluate the expected risks and benefits, estimate the overall odds of a good outcome, and then make a decision that would weigh these factors against any costs (if...

Who takes dietary supplements, and why?

If you’re a regular reader of this blog, I’ll bet you’re not a regular consumer of vitamins or supplements. I’m in that group. Aside from sporadic vitamin D in winter, I don’t take any vitamins or supplements routinely, nor do I give any to my children. Your reasons may be close to mine: There is little to no evidence suggesting that dietary deficiencies...

Death as a Foodborne Illness Curable by Veganism

Most reputable sources of nutrition information recommend a diet high in fruits and vegetables and low in red meat. Vegans go much further. Strict vegans reject all animal products including fish, eggs, and milk. Some vegans come across like religious zealots. Here are some comments recently posted by vegans on Facebook: Right now the biggest social issue facing the world is the...

Should you be “Eating Clean”?

Like many of you I’m interested in the science of good nutrition. In general, I’ve come to be pretty skeptical of the nutritional literature, as so many studies seem to follow the same trajectory that we see with drug studies: Trivial changes in non-relevant outcomes, a failure to consider the results in the context of the accumulated scientific evidence and often, significant...

The Shred Diet: A Minimally Kooky Way To Lose Weight

With New Years’ weight loss resolutions freshly made, let’s take a science-based look at another of the latest diet books being promoted by various public relations agencies. In my last post we explored the claims made by the hysterical Eat To Save Your Life authors in their book featuring a demonic cheeseburger on its cover jacket. Today I will review, Shred: The...

The Dr. Oz Red Palm Oil (non-) Miracle

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...

Everything we eat causes cancer…sort of

Red meat causes cancer. No, processed meat causes cancer. OK, it’s both red meat and processed meat. Wait, genetically modified grain causes cancer (well, not really). No, aspartame causes cancer. No, this food coloring or that one causes cancer. Clearly, everything you eat causes cancer! That means you can avoid cancer by avoiding processed meats, red meat, GMO-associated food (no, probably not),...
