Do vitamins prevent cancer and heart disease?

It is a triumph of marketing over evidence that millions take supplements every day. There is no question we need vitamins in our diet to live. But do we need vitamin supplements? It’s not so clear. There is evidence that our diets, even in developed countries, can be deficient in some micronutrients. But there’s also a lack of evidence to demonstrate that...

A closer look at Dr. Oz’s 15 Superfoods

I’m sure I’m not the only health professional that bites their tongue whenever a patient starts a question with “I heard on Dr. Oz that…” More often than not, I have expectations to realign, and some assumptions to correct. I could easily devote all my posts to simply correcting  information presented on the Dr. Oz show. But given I’m blogging here biweekly,...

Everything Causes Cancer

It’s likely you know someone who has bought into the notion that nutrition is everything, the source of all health and the cause of all illness. Nutrition is very important, to be sure, but it is only one of many possible causes of disease, and if you live in a Western industrialized nation you probably have adequate nutrition. The notion, however, that...

What Can We Learn from the Kitavans?

A Swedish researcher, Staffan Lindeberg, has been studying the inhabitants of Kitava, one of the Trobriand Islands of Papua New Guinea. He claims that sudden cardiac death, stroke, and exertion-related chest pain never occur in Kitava; and he attributes this to their eating a Paleolithic diet. 2,250 people live on Kitava. They are traditional farmers. Their dietary staples are tubers (yam, sweet...

GMO

More bad science in the service of anti-GMO activism

I never used to write much about genetically modified organisms (GMOs) before. I still don’t do it that often. For whatever reason, it just hasn’t been on my radar very much. That seems to be changing, however. It’s not because I went seeking this issue out (although I must admit that I first became interested in genetic engineering when I was in...

CAM Docket: Kardashian Diet Products Klass Action

Kim, Khloe and Kourtney Kardashian permit the use of their names and images of their curvaceous bodies to promote “QuickTrim” diet products, a line of dietary supplements making overblown claims typical of the weight loss supplement industry. Their personal testimonies and formidable publicity machine (Kim alone has over 13 million followers on Twitter), “has reportedly generated $45 million in revenue since they...

Kombucha: A symbiotic mix of yeast, bacteria and the naturalistic fallacy

If you grew up in the seventies, you may remember the same food fads as I do. There was the oat bran buzz that was replaced by the wheat germ movement, the family fondue set and the homemade yogurt maker. And for a while I remember my father making what I called “aquarium water” – a foul-looking jug sitting on the kitchen...

Coconut Oil

In a former life, when I was an Air Force doctor, one of my duties was to give “Healthy Heart” briefings with a script furnished by Air Force experts. It covered the scientific consensus of the time (the early 80s) about diet. It recommended a low fat diet, restricted cholesterol and saturated fat, and demonized tropical oils like palm oil and coconut...

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...
