Working at the intersection of nutrition and health equity | News

December 5, 2022—In this Significant 3 Q&A, Cindy Leung, assistant professor of community health diet at Harvard T.H. Chan School of Public Wellbeing, discusses a new paper she co-authored linking food stuff insecurity and food habit, as perfectly as her other investigate attempts. 

Q: Explain to us about your new examine and the attention-grabbing findings all around food insecurity.

A: Foods insecurity is a socioeconomic ailment of constrained obtain to affordable and wholesome food stuff. In my prior analysis, I observed that men and women enduring foodstuff insecurity are extra likely to have poorer high quality eating plans and are at bigger danger for long-term situations. Meals addiction is a more recent paradigm wherever we’re observing activities of withdrawal and other indications related to people, for illustration, of alcohol abuse, as a consequence of having hugely processed food items. Figuring out that remarkably processed meals are plentiful in lower-profits neighborhoods, we puzzled if men and women who are food stuff insecure could be extra vulnerable to food stuff dependancy.

In two diverse samples—one of minimal-income expecting females in the San Francisco Bay space, and one more of moms of preadolescent little ones in southeast Michigan—we discovered a dependable and substantial good association between foodstuff insecurity and food habit, even just after modifying for sociodemographic components like instruction, race/ethnicity, and profits stage.

In our review, we couldn’t tease apart the mechanisms driving this link, but I imagine that anxiety and ubiquitous access to hugely processed meals are significant elements. Foods insecurity is a resource of continual stress—a regular cognitive process to take care of one’s food items methods in relation to the family’s food items demands. This continual worry may perhaps alter the reward method to overconsume hugely processed foods, raising the risk of food stuff habit in excess of time. The mixture of high tension and quick accessibility to hugely palatable food items might also explain the increased dangers of other persistent ailments that we have witnessed in relation to foods insecurity.

Q: What other analysis concerns are you wanting at?

A: When we speak about interventions for foods insecurity, we instantly go to our federal food stuff programs. All through the COVID-19 pandemic, we’ve observed swift expansions of our most significant nourishment applications, displaying that they are critical levers to decrease meals insecurity during nationwide emergencies. My colleagues and I are analyzing some of these new procedures. I am also definitely fascinated in viewing how poverty alleviation programs could minimize food insecurity. Courses and policies that handle the minimal wage or minimize unemployment could have secondary impacts on blocking food items insecurity, which is so intimately tied to poverty.

Individual from this, I am interested in tests and evaluating environmental interventions to strengthen dietary intake. I have been included in some huge-scale interventions to minimize sugar-sweetened beverage consumption. Currently, I am doing the job with a workforce at the College of Michigan to take a look at a variety of dining corridor variations to decrease crimson meat usage, which is an crucial aim for both health and sustainability explanations.

Q: What does it signify to you as an alumna to be back again at the University as a school member?

I am psyched and humbled to be again at Harvard Chan College, in which I obtained my foundational instruction and launched my vocation. Now, ten decades later, I consider I have a much more holistic point of view of how I can acquire my work to the subsequent phase. I also truly feel very privileged to operate alongside my previous mentors and colleagues, and the more and more gifted pool of pupils that we have.

Overall, I am genuinely optimistic about growing my research program at the School, concentrating on the intersection of diet and health equity. I am deeply fully commited to serving the public well being group in that place.
