Can Food Policy Impact Public Health Goals?
A conversation with Sean Cash, conducted by Friedman student, Lainey Younkin.
Trans fat bans, calorie postings, a proposal to limit the size of sugar-sweetened beverages and the First Lady's Let's Move campaign are all proof that obesity is a national concern. I spoke with Sean Cash, Associate Professor at the Friedman School for his perspective on the role of government food policy in determining our health.
Q. How is food policy being developed in the U.S., specifically with the goals of reducing obesity?
A. "In the past, the government's main nutrition concern was to guarantee nutritional sufficiency. Now we worry that some of these programs, like Supplemental Nutrition Assistance Program (SNAP), may be contributing to obesity. We still have real concerns around food security. There's a bit of a Goldilocks problem of getting things "just right" that policymakers need to consider.
In regard to the goals of reducing obesity, there are questions about how obesity is defined. Should we let obesity and obesity reduction be the sole measure of the success of nutrition policy in this country? With such a strong focus on obesity, do we undermine other important nutrition and physical activity goals? For example, at any weight, physical activity is important and protective against many adverse health outcomes. Perhaps we need to be talking about "misnourishment."
Q. Some people compare the obesity epidemic and food policies to smoking and tobacco policies. Is this a fair comparison? And would similar restrictions on food be effective?
A. It's an imperfect comparison because there is not the same dose response between intake and risk. The universe of substitutions for cigarette is small. Either someone smokes or they don't, but it's not the same with eating. When we try to tax food items or categorize them as "bad" or "good", we risk pushing people into substitutions. If we focus on very narrow categories of food, we leave open a big set of substitutions that may be no healthier.
One interesting point of comparison when we look at tobacco reduction efforts in the past is the cultural shift that eventually occured–taxes increased, and restrictions broadened. Over time, we denormalized smoking to a point where it was no longer a preferred social activity. Could the same happen with food and nutrition? Possibly. People talk about denormalizing soda drinking to decrease intake and we ask if taxes can be one way of reinforcing that larger cultural shift away from soda.
So it's not just about how people respond to price changes now, but also the reminder that it may be a socially non-preferred activity. However, imposing a goal on people that they may not have chosen for themselves is paternalistic and is not a universally welcome role for government.
Q. What's the future of food policy in the U.S.? What will be the areas of interest in the next five years?
A. There has been a real push for selective taxation of foods. I don't think this is a particularly fruitful way to change behavior, but I would not be surprised if some state and local taxes on foods are imposed, particularly on soft drinks. However, people respond marginally to price. Therefore, while taxes may yield a modest behavior change, they likely won't cause a large change in caloric intake or body weight.
An up-and-coming issue to watch is inaccurate or incomplete nutrition labeling. I believe over the next five years, we will see the accuracy of labeling improve.
Finally, we may see reformulations that may prove to be beneficial. For example, if we want to reduce sugar consumption across the board, we may find that reducing the sugar content of sugar-sweetened beverages by (for example) 10% is ultimately easier to do than to reduce consumption of beverages by 10% through taxation or marketing restrictions. The interplay of industry, NGOs, academia and the government can actually move us in healthier directions, even if sometimes the debate around these topics seems intractable.
“Vitamin Sherpa” Ram Shrestha To Deliver Friedman School Commencement Address
Friedman School Alumnus, Ram Shrestha, N90, dubbed the Vitamin Sherpa by Time Magazine will be the Friedman School commencement speaker as 92 students received their masters degrees and 13 receive their doctorates.
Shrestha is best known for interventions in Nepal that provided vitamin A supplementation to Nepalese children, at a time when infant mortality rates and blindness were serious and unaddressed health concerns. For his work, he was recognized as a 2006 Global Health Hero by Time Magazine. Shrestha is also a recipient of the Friedman School “Frontline Award” for his involvement in cutting-edge work in nutrition.
Shrestha will also receive an honorary doctorate of science from the university. Read Time Magazine’s article on Shrestha’s work in Nepal.
Tribute to Scrimshaw
A gathering to remember the life of Dr. Nevin Scrimshaw was held at the Friedman School on April 20th in the Behrakis Auditorium. Scrimshaw was a pioneer in nutrition science beginning with work in Central America in the late 1940’s. In the words of University Professor, and former Friedman School Dean, Irwin Rosenberg, Scrimshaw was “…probably unchallenged as the most important nutrition scientist and nutrition leader in the world.” In 1991, he received the World Food Prize for “revolutionary accomplishments” that had improved” the lives of millions.” Scrimshaw founded the International Nutrition Foundation in 1982, and organization which he led for decades and is housed at the Friedman School. Read more about Dr. Scrimshaw and the Nevin Scrimshaw International Nutrition Foundation.
Student Research Conference
The 7th Annual Student Research Conference, held April 7th, was again host to approximately 200 presenters, attendees, faculty moderators and judges and attracted graduate students from nearly 30 universities and institutions across the United States. The conference, run by Friedman students is a unique venue for graduate students across disciplines to submit and present original research relating to the food system and/or nutrition science. The conference culminated with a panel of guest speakers on the topic “ Everyone at the Table: Multisectoral Approaches to Malnutrition” More about the conference on their website.
Jacquelyn Kercheval, a rising senior majoring in economics and in community health, has been awarded a fellowship from the Tufts Summer Scholars Program to work with Professor William Masters on policies to improve the market for nutrient-dense infant foods in developing countries.
She will collaborate with him and with Friedman School PhD student Marc Nene, building on work conducted through a grant to Masters from the International Food Policy Research Institute (IFPRI) to study the global market for infant foods needed to complement breast milk for children between 6 and 24 months of age. The project will construct a catalog of the complementary foods currently being manufactured and marketed all around the world, and it will subject a random sample of these to laboratory testing for nutrient density. Kercheval will start on this project in late May of 2013, and expects to use project data for her Senior Thesis in economics the following year, as a foundation for graduate school in public health.

PUBLICATIONS & ARTICLES
Sean Cash and co-authors from the University of Alberta recently had their manuscript, "Impact of community-based HIV/AIDS treatment on Household Incomes in Uganda" accepted for publication in PLOS One. This paper is the first published study to quantify the impacts of successful antiretroviral treatment on the livelihoods of impacted households in rural patients in Africa.
William Masters was quoted in The Atlantic magazine on travelling to countries with hyperinflation. "Hyperinflation is among the most cruel forms of government expropriation,… Masters has various pieces of Zimbabwean currency framed on a wall in his office, for novelty, including a standard-issue note from January 2008 that says in small letters, 'Pay the bearer on demand ten million dollars on or before 30th of June 2008.'" Read The Atlantic article.
