Diet and exercise versus cancer: A science-based view

One of the most effective spin techniques used by advocates of “integrative medicine” (also sometimes called “complementary and alternative medicine,” or CAM for short) to legitimize quackery has been to claim basically all non-pharmacologic, non-surgical interventions as “integrative,” “complementary,” or “alternative.” Thus, science-based interventions such as diet changes to treat and/or prevent disease, exercise, and other lifestyle alterations are portrayed as somehow...

The cost of repealing mandatory motorcycle helmet laws

It’s a seldom mentioned aspect of my professional history that I used to do a lot of trauma surgery in my youth. I did my residency at a program that included a county hospital with a busy trauma program where I saw quite a bit of vehicular carnage and an urban hospital (which has since closed) where I saw a fair amount...

New evidence, same conclusion: Tamiflu only modestly useful for influenza

Does Tamiflu have any meaningful effects on the prevention or treatment of influenza? Considering the drug’s been on the market for almost 15 years, and is widely used, you should expect this question has been answered after 15 flu seasons. Answering this question from a science-based perspective requires three steps: Consider prior probability, be systematic in the approach, and get all the...

Autism prevalence: Now estimated to be one in 68, and the antivaccine movement goes wild

There used to be a time when I dreaded Autism Awareness Month, which begins tomorrow. The reason was simple. Several years ago to perhaps as recently as three years ago, I could always count on a flurry of stories about autism towards the end of March and the beginning of April about autism. That in and of itself isn’t bad. Sometimes the...

Vaccines work. Period.

Over my blogging “career,” which now stretches back nearly nine years, and my hobby before that of engaging in online “debates” on Usenet newsgroups back before 2004, I developed an interest in the antivaccine movement. Antivaccinationism, “antivax,” or whatever you want to call it, represents a particularly insidious and dangerous form of quackery because it doesn’t just endanger the children whose parents...

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),...

Are Cell Phones a Possible Carcinogen? An Update on the IARC Report

EDITOR’S NOTE: Because I am at the annual meeting of the American Association for Cancer Research in Chicago, between the meetings, working on a policy statement, working on a manuscript, and various other miscellaneous tasks, I alas was unable to produce a post worthy of the quality normally expected by SBM readers. Fortunately, Lorne Trottier, who’s done a great job for us...

Hyping Health Risks

Three kids on the same block were diagnosed with leukemia last year. That couldn’t happen just by chance, could it? There MUST be something in the environment that caused it (power lines, the chemical plant down the street, asbestos in their school, iPods, Twinkies?). Quick, let’s measure everything we can think of and compare exposures to other blocks and find an explanation....
