Announcing the next Diversity in Science Carnival!


In honor of Hispanic Heritage Month in the U.S., Larval Metamorphosis is hosting the Diversity in Science blog Carnival with Alberto Roca of Minority Postdoc.

This month’s theme will be Latino / Hispanic Health: Science and Advocacy. Latinos / Hispanics are the ethnic group most impacted by the obesity epidemic in the US. They are more likely to be overweight and obese and twice as likely to be diagnosed with diabetes compared to non-Hispanic whites. How can we reduce these health disparities? Unfortunately, the science behind the causes of overweight and obesity and diabetes are based on epidemiological studies of cohorts of non-Hispanic whites. And, despite efforts to reduce health disparities in Latino / Hispanic communities, they keep increasing. So, what types of studies are needed? What types of approaches work? We would love to hear what you think!

Suggested topics include, but are not limited to:
  •  Personal stories of health, science, and advocacy
  •  The science behind the causes of obesity and diabetes in Latino / Hispanic communities
  •  How to reach Latino / Hispanic communities

Anyone can participate by submitting new posts as well as relevant posts from their archives. You can submit posts by email (please put ‘DIS blog carnival’ in the subject line) or using the online form. The deadline for submissions is October 29, 2012.

The Good, the Bad, the Ugly: Ancestral Health Symposium 2012

It's been one week since the Ancestral Health Symposium and it's taken about that amount of time for everything to sink in and for me to fully process the experience. In short, I love that AHS is a unique forum for discussing unconventional topics and approaches in nutrition and public health. But I feel that in its current state loses credibility as an important 'scientific conference.' Here's why. 

The Good:

I learned the most from the talks that focused on food policy and regulation, especially the panels by Baylen J. Linnekin, Margaret Sova McCabe, and Emily Broad Lieb and Peter Ballerstedt, Anna Kelles, Lynda Frassetto, and Adele Hite; and the talk by Robert Lustig.

One of the most shocking things I learned was that some of the corporate sponsors of the American Society of Dietetics and Nutrition, through which all RDs and nutritionists have to be licensed in order to practice, include Coca Cola, PepsiCo, Mars (!!!), Kelloggs, and General Mills. Yeah, this nation is screwed.

But the points that Baylen made stick with me the most. We were all at AHS because we share dietary beliefs that are outside mainstream and local, state, and federal government policies, laws, and regulation impact how and what we want to eat. But should they regulate what we eat? What if we put food into the first amendment in order to prevent them from regulating what they eat? Given the bad job they've done so far with regulating food (ahem, MyPlate), I think that's a pretty fascinating idea.

Because, from the other talks I attended, it's pretty clear that other policy options aren't working. For example, Jennifer Pomeranz discussed the problems with limiting marketing to young children. The US can't restrict commercial speech because of the First Amendment. The FDA can protect us from false commercial speech but doesn't have much power to enforce it. They don't have the resources to test the validity of every false claim companies make for the healthfulness of their products.

Robert Lustig also pointed out that the government guidelines, PI campaigns, warning labels, public school education, menu labeling have not worked. He claims that sugar meets the same criteria for addiction as other substances that are regulated; like alcohol, it is toxic AND abused. But should the government tax sugar, restrict access, or interdict?

Creating a 'nanny state', or whether the government should be telling us what we can or can't eat, is one of the hottest topics in government right now. I'm not sure I support a nanny state, because it could equally be applied to saturated fat!!!

The Bad:

 Our panel entitled 'Working to Reclaim Ancestral Health in Latino Communities' was bittersweet. Armida Ayala, a Mexican anthropologist who is working in Latino communities in LA (including my hometown of Wilmington!) to provide nutrition information and access to healthy foods, gave an inspiring talk about how we need to 'take evolution out of the cell and into the moral compass'. Her point was that in order to solve the obesity and diabetes epidemics, we need to use our evolutionary capacity for empathy and practice social justice by helping Latinos and African Americans get healthier in order to be healthier as a whole society. It was beautiful and breathtaking.

The bitter part was that the session was poorly attended because they scheduled it at the same time as the 'Safe Starches' debate, which is really sad. The sweet part, though, was that the people who were there were super passionate about the topic and already working in their communities. I know that something awesome will come of it.

We also got some pretty amazing feedback on the session. Someone told me that it was the only session with emotion - corazón - at the conference. Around the blogosphere: Paleo for Women liked our session and made a similar call for action and Alec Henderson thought that we had the answer to the obesity epidemic.

The Ugly:

Everyone seems to have their pet diet, which made a lot of the conference seem like an Ego show rather than a scientific conference. One of the worst examples was Robb Wolf's talk. He was giving a pretty good presentation about the use of the Paleo diet to help Reno police officers lose weight and improve their metabolic profiles, which saved the department a significant amount of money, until he went off about his pet theory that obesity and metabolic syndrome is caused by intestinal permeability and inflammation and showed some pretty unimpressive cherry-picked studies that demonstrated metformin reduces intestinal permeability by affecting tight junctions.

But the most cringe-worthy was the Q&A session after Stephan Guyenet's talk. Last year, he got hammered by Gary Taubes about his theory about carbohydrates and food reward during the Q&A session. He started off this year's talk with a smug, 'I won't be talking about carbohydrates this time', then went on to discuss the role of gut microbiota and health in obesity and metabolic syndrome. He brought up a study that demonstrated that people who were born via cesarean section have higher rates of obesity than those born via vaginal birth, then went on to discuss how this could be because the babies born via cesarean section were not exposed to the proper gut microbiota during the birthing process. But then Robert Lustig got him during the Q&A, pointing out that what he presented was just a hypothesis and he never mentioned that it could have been the reasons that made the women have a cesarean section (e.g., gestational diabetes) that influenced obesity risk for the babies later.

He brought up a good point. Whenever these people bring up their pet ideas, they usually don't present them as hypotheses. Instead, they present them as fact by showing papers from PubMed that support their tenuous claims. The other unique thing about AHS is that there are a lot of non-scientists in the room. But I feel that the way they present their ideas is misleading to this group of people that would have a really difficult time distinguishing well-supported data from hypotheses. It's like they do it because they're more concerned about making money than actually helping people and our country.

Will I attend next year?

I'm not sure. I feel that AHS has to define it's goals more clearly. If it wants to be a credible scientific for discussing nutrition, then I think the people who give scientific talks should actually be scientists working in the field. Right now it's just people who scan PubMed in their free time.

But I do feel that if there's any way to gather people who are thinking outside of the box, such as Armida Ayala, Adele Hite, and Baylen Linnekin, in order to solve this country's modern health challenges, there's no better place than AHS.

EPIC update and the Ancestral Health Symposium

I am SO excited because today the Ancestral Health Symposium begins!

The Ancestral Health Symposium, sponsored by the Ancestral Health Society, is a scientific conference focused on developing solutions to modern health challenges by approaching health from an evolutionary perspective. To me, that means a conference based on an unconventional view of nutrition.

I found out about it for the first time last summer from Nom Nom Paleo and Fitbomb, two blogs that I began following after my diagnosis. When I heard about it, I decided that I would do everything I could to attend the following year. So, as calls for proposals went out while I was in Chile, I submitted a proposal for a panel on Health in Latino Communities with my colleague Armida Ayala. Our panel is tomorrow; I'll share more about it later.

A lot has happened since last year, though. Heck, a lot has happened even in the past six months, which I've been promising to share. The two most important things that happened that changed some of my views on nutrition in the past year are: 1) I met Adele Hite, and 2) I participated in an Intuitive Eating course.

1) I first learned about Adele Hite in a video posted on YouTube, in which she discussed the problems with the one-size-fits-all approach to nutrition. Later on I found out that she is very passionate about this topic, even testifying at the 2010 Dietary Guidelines Press Conference. Her message hit so close to home, that I had to get to know her. 

Adele is a Masters of Public Health and Registered Dietitian candidate at the UNC-Chapel Hill School of Public Health. Before graduate school, she worked in the Duke Lifestyle Medicine Clinic, run by Eric Westman, which promotes reducing excess carbohydrates for weight loss and improved health. For more about Adele's journey and activism, check out this interview.

To make a long story short, I contacted her and we made a phone date. She shared some of her thoughts on nutrition, including her observation that many food seeking behaviors and even eating disorders are tied to a lack of animal protein in the diet. She also shared a document that she developed called 'DIY nutrition', which I refer to frequently now (and is available to share, if you are interested). In it, she lists essential foods we need to build a healthy body. Contrary to the current dietary guidelines, at the top of this list are proteins and fats. Following this are beneficial foods and optional foods. Finally, she lists clues that your current dietary choices are not working for you. The beauty of it is that it can be tailored to each person's biology and lifestyle and doesn't give hard and fast guidelines, which can cause a lot of feelings of guilt around certain foods. Which brings me to my next point.

2) I participated in an Intuitive Eating course at Harvard this Spring. Intuitive Eating is an approach (detailed in a similarly titled book) that teaches you how to create a healthy relationship with your food, mind, and body based on 10 principles. One of my friends signed up initially to tackle some emotional eating problems she has, but asked me to join because she didn't want to go alone. Initially, I signed up to help her out but soon realized that I needed it myself!

After my diagnosis last year, I admit that I developed an unhealthy relationship with food. I became very restrictive with carbohydrates, which triggered some binge eating episodes. This isn't my first experience with binge eating, though. I went through another period in graduate school, when I was being very restrictive with food in order to lose weight. Those last three sentences are very difficult to write, but I wanted to let others know that I'm not perfect and I hope they help others who have experienced the same thing.

Intuitive Eating taught me to reject the diet mentality (low-fat AND low-carb) and to make peace with food. In essence, no foods are 'good' or 'bad' because this kind of mentality can trigger eating disorders. Instead, you're supposed to listen to your body cues such as hunger and fullness and how foods make you feel.

The last part of the Intuitive Eating course was on nutrition. They saved it for last because they don't want people to become fixated on food rules again. However, I think some of the things they mention in the book, especially that red meats and saturated fats are harmful, are incorrect.

That's where I refer to Adele Hite's DIY nutrition document. Combining these two approaches, I feel that I have developed a healthy relationship with food AND am honoring my health. I found that I can still eat ice cream or bread, for example, without experiencing anxiety and I can maintain a healthy weight.

I am a little anxious, though, to attend AHS, now that my views don't completely line up with Paleo or Primal or low-carb anymore. I'm afraid someone will catch me drinking a beer or eating a (open-faced) sandwich!

But that's not what the conference has become for me. Instead, it's an opportunity to meet some of my heroes. People who changed my view of nutrition guidelines and helped me overcome an eating disorder. Top of my list is Adele Hite, who I'll get to meet in person. I'll also get to meet Gary Taubes, who threw my views of saturated fat on their head. I'll also get to hang out with Dr. Georgia Ede, the Harvard psychiatrist that diagnosed me in the first place.

Because these are the people that are going to change the government's and the public's perception of nutrition and health (physical and mental) in order to tackle our modern health challenges.

SACNAS newsletter article

I know it's been a loooong time since my last post. A lot has happened - which I hope to post about in an epic update ASAP - including writing this FEATURE article for the SACNAS newsletter about my personal experience with conventional nutrition recommendations and why they may be inappropriate for Hispanic and Native American communities. Let me know what you think!
