Why the Food Babe is wrong (it’s not just because she’s ignorant)

You knew I had to talk about Food Babe this week.

My not-so-secret goal with this blog is to improve public science literacy and to help people become more critical consumers of information. As a consumer activist and critic with enormous influence, one might hope that Food Babe’s goals are similar to mine.  But I’m afraid I have to give her methods a big red F, and for distressing reasons. Before I get into that, however, I want to give readers who aren’t familiar with Food Babe some background.

Like the decision to vaccinate, the choices we make about food have significant consequences to our health.  It’s easy to find advice on how to structure our diet–there is an overwhelming volume of admonitions to eat more protein!, only organic!, less fat!, more fat!, plant-based!, paleo!, non-GMO!, raw!, Mediterranean!, gluten-free! with dire warnings about what will happen if we fail to follow that plan exactly. (I feel particularly sympathetic to parents of young children, who are already stressed out about the incredible day-to-day challenges of raising them in a difficult economy. Shaming them if they’re buying most of their food in bulk once or twice a month at Costco instead of shopping exclusively for their children at Whole Foods is outrageous.  In fact, the very ability to make choices about what we eat is a privilege not shared by a huge proportion of the planet’s population…but that’s a subject for another post).

For the average person untrained in science, nutrition, or medicine, the challenge of wading through this mountain of advice on how one “should” eat, sorting out the good advice from the bad, can be daunting.  With so many options it’s easy to succumb to decision fatigue–or default to way too many meals at fast food joints.

Diet and health gurus are counting on this. They offer people a simple solution: follow my “movement”, follow my advice and you don’t have to think for yourself about this; follow my simple “tricks” and you’re guaranteed “health”, “thinness” and a sense of belonging to a righteous movement.

Enter “Food Babe” (whose real name is Vani Hari).

Please don’t politicize vaccine refusal

Given recent measles outbreaks and the ravenous news cycle, it was inevitable that public attention would shift to politicians’ position on vaccination. Some commenters are reacting by politicizing the vaccine debate, painting conservatives or the tea party (or, in response to those messages, liberals) as anti-vaccine. Please don’t let this message take hold. It’s wrong, it’s dangerous, and it’s counterproductive.

The president set off a small chain reaction by advising parents to vaccinate, but Governor Chris Christie’s comments have drawn the most attention. His statement was almost meaningless; he told reporters that (of course) he vaccinated his own children, and “that parents need to have some measure of choice in things as well so that’s the balance that the government has to decide.” Vaccination is not strictly mandatory in any state, and most states permit exemptions for the few parents who have ideological objections to modern medicine, so as a matter of simple fact the government has already decided and given parents that choice. (He went on with a few more comments, but other than to say that obviously we disagree with them, there’s not much point in dissecting them here.)

Christie is a politician who wants to avoid unnecessary controversy. After the first negative reports of his comments emerged, he distanced himself from anti-vaxers by firmly stating, “there is no question kids should be vaccinated.” But it was too late. The public picked up on his initial remarks and fed him straight into the gnashing teeth of the news cycle. And once the meal started, other prominent politicians with an eye on 2016 staked out seats at the table. Rand Paul seemed to give credence to some anti-vax myths, although he, too, backed down a bit and clarified that vaccines are “a good thing.” His fellow conservative (and fellow physician) Ben Carson pushed back on those statements, backing vaccination and even comparing anti-vaxers to secondhand smokers. Hillary Clinton, the three conservatives’ bête noir, came out with her own strong, respectable and simple message: “The science is clear: The earth is round, the sky is blue, and #vaccineswork. Let’s protect all our kids.”

Notice something about these statements? Even the most ant-vax statement isn’t all that opposed to vaccination, compared to what you read online. That’s no surprise. The overwhelming majority of parents vaccinate their kids, and politicians who offend overwhelming majorities retire early. But you’re going to read a lot of headlines and tweets about how Rand Paul and Chris Christie are anti-vaxers because they’re pandering to the voters; you may even see people promoting the meme that Republicans (or conservatives or Tea Partiers) are anti-vax now. Don’t buy it.

Why you should vaccinate your children

Andrew Wakefield’s fraudulent report that the MMR vaccine causes autism has resulted in a generation of children (~age 10-16) who have a historically low vaccination rate (below 50% in some places). As a result, the rate of measles infection has skyrocketed in Britain:

There have also been outbreaks in the United States, with significant infections so far this year in many places, including Brooklyn and New Jersey.

The good news is that thanks to excellent public health outreach in England, vaccination rates are improving significantly. But I worry that many people still don’t understand the issues. Let me summarize them for you:
