Evaluating milk and its substitutes

I knew milk alternatives were becoming mainstream when a new bakery/café appeared in my neighborhood. I ordered a latte and learned that they didn’t use milk. At all. Not only were the baked goods vegan, organic, “natural” and some were gluten-free, they were completely dairy-free for their coffee beverages. While everything looked and smelled great, I was shocked that they had no...

How not to report about vaccine safety issues, Toronto Star edition

I remember it well, because several of my readers forwarded it to me not long after it appeared on the website of the Toronto Star: An eye-catching headline proclaiming a “wonder drug’s dark side,” that “wonder drug” being Gardasil, one of two vaccines against the human papilloma virus (HPV) designed to prevent cervical cancer by preventing infection with the HPV virus.

What do we do about politicians and physicians who promote antivaccine misinformation?

There are politicians and physicians out there promoting antivaccine misinformation. None of us expect politicians to be scientists or physicians, but we do expect them to listen to them.

Screening for disease in people without symptoms: The reality

One of the most contentious questions that come up in science-based medicine that we discuss on this blog is the issue of screening asymptomatic individuals for disease. The most common conditions screened for that we, at least, have discussed on this blog are cancers (e.g., mammography for breast cancer, prostate-specific antigen screening for prostate cancer, ultrasound screening for thyroid cancer), but screening...

Gut Check. Probiotics and Metabiome.

I had an editor who commented that the titles of my essays are often obtuse. Probably true. In going back over my essays on SBM I often can’t tell from the title what I have written about until I...

The Disneyland measles outbreak: “Dr. Bob” Sears says measles isn’t that bad, and an antivaccine activist invokes the Brady Bunch fallacy

One argument antivaxers frequently make about the measles is that it's not dangerous. As "evidence" of this contention, they will often cite examples of sitcoms and cartoons from a half a century ago or more when measles was played for laughs. This is a fallacious argument, and there was a profound disconnect between the popular perception of measles and its reality.

Glyphosate – The New Bogeyman

There is an ideological subculture that is motivated to blame all the perceived ills of the world on environmental factors and corporate/government malfeasance. Often this serves a deeper ideological drive, which can be anti-vaccine, extreme environmentalism, or anti-GMO. The latest environmental bogeyman making the rounds is glyphosate, which is being blamed for (you guessed it) autism. Glyphosate is the active ingredient in...
