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).

Actions undertaken without understanding  are always foolish, and often dangerous.

New paper deals blow to hypothesis that Native Americans have European ancestry

The idea that Native Americans had at least some ancestry from a trans-Atlantic migration has been around since the earliest days of American anthropology. The earliest proponents of this idea looked at the spectacular burial mounds and art from North America and insisted that they could not have been made by the ancestors of the indigenous (or as they put it, “primitive”) peoples they encountered. Obviously, they reasoned, a “Lost Race” of “Moundbuilders” (identified variously as Atlanteans, Europeans, and Israelites) must have been responsible for the great archaeological sites in North America. But systematic excavation of these sites has thoroughly debunked that idea.**

Nevertheless, an idea that there must be a European origin for at least some Native Americans has persisted in various forms. In its modern iteration, this idea is known as the “Solutrean Hypothesis.” The Solutrean hypothesis claims that the Clovis people, the makers of the earliest known stone tools in the Americas, were the cultural and biological descendants of the Solutrean peoples of southwest coastal Europe.

I have written before about why the genetic diversity present in contemporary and ancient Native Americans does not support this hypothesis (“Problematic science journalism: Native American ancestry and the Solutrean hypothesis”). Here, I want to discuss a new challenge to the Solutrean hypothesis that came out in the archaeological literature just today.  Continue reading

Darwin Day!

Think hard. Go deep.

Happy Darwin Day, everyone! Thanks for helping to make the Violent Metaphors community a place where we celebrate intellectual bravery and relentless curiosity, in keeping with Darwin’s legacy.

Here are a few links in honor of today:

  • Did you know that Darwin’s children doodled on his “Origin” manuscript? You can see their sketches here.
  • Creationists tend to raise the same objections to evolution over and over again. Here are Phil Plait’s responses to a number of them (h/t to Washington Post for the last two links ).
  • If I’m being completely honest, I found “On the Origin of Species” to be a rather boring book. World-changing, but not a thrilling read. “The Voyage of the Beagle”, on the other hand, is fantastic and I highly recommend it! You can download the full book for free here.
  • What does it mean to be human? Understanding the history of our species helps us answer this question. If you’re a little rusty on your human paleontology, the Smithsonian Museum of Natural History has an excellent, easy to read guide for you.
  • Help improve science education in your community by visiting the National Center for Science Education’s webpage. They keep track of legislation that threatens science education in public schools, and have resources for community members who want to help.
  • Finally check out this page to find an event in your town celebrating Darwin today! I’m planning on toasting the great man tonight with a nice bottle of champagne (sent to me by one of my mentors as a congratulatory gift for becoming a professor. It seems fitting!).

Have you got any evolution-related links you’d like to share? Please post them in the comments!

Dear parents, let’s talk about measles

A bit of personal news

I’m absolutely delighted to announce that I’ve just accepted a position as Assistant Professor-Molecular Genetics of Human Evolution in the Anthropology department at the University of Kansas. KU has a very long tradition of producing top-notch anthropological geneticists, and I’m honored to be joining the department as a teacher and researcher.

I’m deeply grateful to my mentors, particularly Deborah Bolnick, Geoff Hayes, Dennis O’Rourke, Rika Kaestle and Beth and Rudy Raff, who provided so much guidance to me throughout the whole process. I’m also grateful for the wise perspectives and support from my dear friends Lyn Christian, Lisa Twight, Jeff Rabhan, my fabulous labmates, and my family (especially Colin).

Mentoring is everything in science.
Mentoring is everything

And now that the job season is over for me, I’m looking forward to having more time for writing here–we’ve got lots of science to talk about. Onward!

Storytelling vs. science

Things are not always what they seem.
Things are not always what they seem.

Several organizations exploit vulnerable parents by claiming that they can “cure” their children’s autism through various approaches.

As Left Brain, Right Brain observes, these “autism cure” movements persist because of the power of storytelling:

“Nothing sells unproven “treatments” like testimonials. For autism it has been true since the days of chelation and even before that. Tell people that your “treatment” cures autism and you have testimonials to show it and you can just about guarantee sales.”

As we all know, anecdotes aren’t scientific evidence, but they do appeal to us on an emotional level. Unfortunately, one woman’s recent experience has starkly illustrated just how untrustworthy such stories actually are.

Camile Saulnier (a pseudonym) was recently given a book by Kerri Rivera called “Healing the Symptoms known as Autism”, which prescribed a “Treatment” for curing autism:

“I began looking into the background of CD/MMS and I was extremely concerned to find that MMS (Sodium Chlorite + Citric Acid = Chlorine Dioxide) aka. ‘CD’ was and is being hailed and marketed as a cure for almost every ailment and disease known to mankind, this includes Cancer, Malaria, Aids and Ebola.

I found the man behind MMS to be one Jim Humble, the Arch-Bishop of a rather cult like church named the “Genesis II Church”. Suffice to say I was very worried indeed, I searched further and found that Kerri Rivera the author of the book “Healing the Symptoms known as Autism” is a Bishop within this church.

I voiced my concerns with my friend who was following the Protocol, but she seemed to be un-phased by my doubts. She directed me to the facebook group CDAutism, where she said I will find proof of the recovery stories and thousands of parents giving testimony to the marvelous gains achieved by using the CD Protocol.”

Saulnier was justifiably concerned and spent some time reading the group’s posts, learning that the linchpin of the group’s claims was the collection of testimonials of parents of “recovered” autistic children. Saulnier was skeptical about the reliability of these testimonials, as they were all posted by Kerri Rivera, and so devised a little test to see how Rivera determined what “recovery” was and whether it was the CD treatment that caused “recovery.”

“I had an idea to see for myself, I needed to be sure 100% that everything I was seeing and reading was real before I could even consider using this protocol. I am afraid my worst fears were not only imagined, they are real.

I made a recovery story for my child, based on so many others which I had read, I felt bad doing it as I do not like to pretend but it was for the sole purpose of finding a greater truth.”

Saulnier’s false testimonial was immediately and enthusiastically posted by Kerri Rivera on the group’s website, and the banner proclaiming the number of children “cured” of autism was promptly updated to reflect this false cure. You can read the details of Saulnier’s correspondance with Rivera here.

Now, I’m not at all comfortable with Saulnier’s approach. I don’t believe that it’s ethical to lie. But having said that, it is a fascinating glimpse into the credulity of this segment of the alt-med community. Can you imagine how this would have played out in the science-based medical community? What level of scrutiny would such a story have been subjected to by physicians and medical researchers before they accepted it as true?


Several readers of this blog are persons on the autism spectrum and have contributed their perspectives in discussions on vaccination and autism. I’d particularly love to hear their thoughts on this issue.

Closing my browser tabs 12/15/14

Here are some serious and not-so-serious things to read about science as you drink your eggnog this week.

Vaccines

“Vaccines work. Here are the facts” is an awesome cartoon by Maki Naro, refuting the antivaccine arguments and giving a great and accessible overview of why vaccination is important. This deserves to go viral, so please share it with your friends! And while you’re on the treadmill or walking your dog this week, take a listen to “The Most Important Playground Conversation”, a discussion hosted by Voices for Vaccines in which VM writer Colin discusses strategies for discussing vaccination science with other parents.

Science publishing

Retraction Watch just received a $400,000 grant from the MacArthur Foundation to develop a database of retracted papers. This database would mean that scientists could check that the literature they rely upon in writing grants and papers haven’t been retracted. And they’re hiring an editor and database developer! This is outstanding news for those of us concerned about improving the quality of scientific publications.

Women in Science

Women have played a meaningful, but largely unrecognized, role in the history of amateur radio. The Mary Sue has a great article honoring female ham radio operators, which I particularly enjoyed because I’m one of their number! To my fellow YLs, 33 from KF5ZMF!! To everyone else, check it out and consider studying for your ham license! It’s not incredibly difficult, and it’s tremendous fun.

Science literacy and skepticism

I really like “Ask for Evidence”, a guide to evaluating the legitimacy of scientific and medical claims. It’s a simple, straightforward and clear explanation, and a good potential teaching tool. Explore the site–there are a bunch of posts by specific topic as well! You might, for example, use these approaches when evaluating claims made by the “Food Babe” who recently revealed some serious shortcomings in her understanding of chemistry.

Research

Did you know that the human milk microbiome has been characterized? That the flora present within human milk differs between mothers who gave birth vaginally and by caesarian? This post gives a really great explanation of this fascinating research.

Sweet Science

Tommy Toehold is hands-down my favorite combat sports cartoon journalist. (If you’re an MMA fan, then you’re probably nodding your head right now). I’m mentioning him in this post because he recently did an awesome video about the women’s MMA show that my sister is the matchmaker for, “How Invicta Took Over The World”. I’m a bit biased, but the latest Invicta show in Houston last week was pretty incredible, and he really gives a great introduction to the show. However, I still think that Tommy’s funniest video of all time is this one of Joe Rogan and Mike Goldberg commentating on the EA UFC game’s glitches. (Warning: language in these videos is safe for neither work nor children.)

Finally, just a reminder that if you want daily links to science stories I find interesting (some of which I included above), “like” the VM page on Facebook!

Yes, doctors know what they’re talking about: Refuting a common anti-vaccine argument.

I usually don’t respond to many comments on my blog, preferring instead to encourage conversation between readers. I also don’t typically close comments on any of my pieces, so conversations and reactions continue for a long time. Sometimes that takes the discussion in an interesting direction. I think that a few recent comments on my “Dear parents…” piece are worth highlighting, as they provide an excellent window into an ongoing discussion of a very common anti-vaccine argument.

A scientist was asked to review a new paper. You’ll never guess what happened next!

_KCM4407(Apologies for the egregious clickbaity title.)

 

A professor I know was recently sent a manuscript to review from PLOS ONE. Nothing unusual in that…except that it was his own paper. After briefly debating how to respond, he accepted the invitation to review the paper, and submitted the following review:

I live only 2 hours from the Ebola hospital in Dallas. Here’s what I’m doing to protect my family.

We Americans sometimes seem to have only two settings when it comes to public health issues;  “unconcern” and “panic”. (I think the media deserve a great deal of blame for this, but that’s another blog post).  The last few weeks have seen the switch flipped to near panic about Ebola, after the recent infection of two Texas Health Presbyterian nurses who were treating infected patient Thomas Eric Duncan, and possible exposure of additional people after one of the nurses took a commercial flight.  The fact that forty three individuals who had direct contact with Mr. Duncan have now passed the 21 day incubation period for the disease without signs of infection, that Senegal has been declared free from Ebola (no new infections have occurred there for 42 days), that Nigeria is close to the same milestone, and that the two nurses who treated Mr. Duncan, Amber Vinson and Nina Pham, are doing much better, don’t seem to make much of a dent in the fearmongering I’ve seen in recent weeks.

And now with the report that a physician with Doctors Without Borders, who recently returned to his home in New York City from West Africa, has tested positive without Ebola, the “Ebola panic” is just going to get worse.

So given the fact that I live so close to the “Ebola hospital” (just two hours!) I thought I’d share with my readers what precautions I’m taking to protect my family’s health. Continue reading
