New research explores how food insecurity affects stress and mental health
Study finds that hardship with low quality of diet cannot build resilience

According to the U.S. Department of Agriculture, 13.5% of American households experienced food insecurity at some time during 2023. That means 18 million families didn鈥檛 have enough to meet their needs and often didn鈥檛 know where the next meal would come from.
In her past research, 海角乱伦社区 Associate Professor Lina Begdache, PhD 鈥08, has explored how our diets affect our mental health and overall moods. But how does a lack of nutrition change our resilience, stress mindset and level of mental distress, particularly across age and gender?
In , Begdache, Assistant Professor Melissa Zeynep Ertem and their team investigated these relationships using survey data from 1,099 people, with 70% of participants under 30 years old.
As part of her overall research, Begdache 鈥 a faculty member in health and wellness studies at 海角乱伦社区鈥檚 Decker College of Nursing and Health Sciences 鈥 likes to compare how diet affects young adults compared to older adults, since the human brain is not done maturing until the mid- to late 20s. She admitted that some of the findings from this paper surprised her.
鈥淩esilience builds off hardship, but it looks like hardship with low quality of diet cannot build resilience. We are probably the first to report that,鈥 she said. 鈥淲e also didn鈥檛 find that food insecurity affects the stress mindset. People could still be happy or have a positive thinking even though they have food insecurity, so it鈥檚 more related to their personality traits rather than the quality of their diet.鈥
The questionnaires also asked about participants鈥 activity levels and factored those responses into their overall health scores.
鈥淓xercise is known to modulate brain chemistry, and in this research, we found that exercise was associated with improvements in neurobehaviors, including your stress mindset,鈥 Begdache said. 鈥淚f you have negative thinking, you can exercise regularly and improve the way you think about stress. It improved resilience, too 鈥 specifically, resilience was highly associated with exercising.鈥
Ertem, a faculty member at the Thomas J. Watson College of Engineering and Applied Science鈥檚 School of Systems Science and Industrial Engineering, contributed her skills in data analysis to the research. She believes it is important to assess the effects of American food policies after the pandemic.
鈥淒uring COVID, there were some extra incentives where government provided food items for vulnerable populations,鈥 Ertem said. 鈥淎fter 2023, most of the extra benefits like Pandemic Electronic Benefit Transfer and extra SNAP benefits have concluded. One of the big question we want to answer was how food insecurity might affect young adults, especially after those incentives are gone.
Begdache thinks the new research is important for understanding how food insecurity affects psychological resilience, mental well-being and stress-related perceptions, but it also has broader implications.
鈥淚f we take these findings and translate them into the current American diet, we鈥檙e not consuming the best quality, which means that this may be affecting our resilience level,鈥 she said. 鈥淭he literature has shown that the Mediterranean diet, which has a spectrum of wholesome food, is associated with resilience. If we improve our quality of diet, we may be able to develop resilience and improve our mental health as well.鈥
Also contributing to the research were Ertem鈥檚 students Amera Al-Amery, PhD 鈥23 (now an assistant professor at the Princess Sumaya University for Technology in Jordan), Katerina K. Nagorny ’24, Ushima Chowdhury 鈥25 and Lexis R. Rosenberg 鈥23.
