How the Mediterranean Diet Might Help Protect Against Depression

Lauren Patterson, Computer Science/Economics Major, Emory University • April 1, 2026

Feeling low or mentally drained is something most of us experience at some point. Depression is prevalent in every corner of the world, and it affects people’s ability to do everyday tasks. This mental health disorder is often linked to complex interactions between genetic, environmental, and lifestyle factors. In more recent years, researchers have begun to explore how diets may actually play a role in the onset and management of depression. Sánchez-Villegas sought to explore the connection between following a Mediterranean dietary pattern and the incidence of depression among healthy individuals. She chose the Mediterranean diet because it emphasizes the consumption of fruit, vegetables, legumes, nuts, whole grains, fish and olive oil, while also limiting the intake of meats and sweets. This type of diet has been known to improve neurological activity. The study’s main objective was to determine whether individuals who follow this dietary pattern are less likely to develop depression over time.

So how did the researchers actually study this connection? This prospective study was longitudinal as it followed a group of 10,094 Spanish university graduates from the (Seguimiento Universidad de Navarra) over many years. At baseline, all participants were free from clinical depression and filled out a validated food frequency questionnaire designed to measure adherence to the Mediterranean diet. The adherence was scored from 0 to 9, low to high, based on the consistency of their consumption of key dietary components. Then participants were given the questionnaire periodically over a few years; the duration of this following period varied from participant to participant, but the mean was 4.4 years.

The researchers found a clear inverse relationship between how closely the participants followed the Mediterranean diet and their risk of depression. Specifically, their results yielded that those who scored high (6-9 points) on the diet adherence scale had about a 30% lower risk of developing depression compared to those with low adherence (0-3 points). When statistically running these results, the researchers controlled confounding factors such as age, physical activity, smoking, and total energy intake. The protective effect of the diet is thought to stem from its high levels of omega-3 fatty acids, antioxidants, and B vitamins, which have been shown to support brain health and reduce inflammation.

These findings are important because they suggest that diet—which is a modifiable lifestyle factor—may be a useful tool in preventing the onset of depression. Unlike medication or therapy, which often come after symptoms arise, promoting healthy dietary habits from a young age could be a proactive way to protect our mental well-being. If you’re a student or young adult navigating a high‑stress environment, adopting a Mediterranean‑style diet might offer both physical and emotional benefits. 

 

Universities could incorporate education on nutrition into wellness programs, promote healthier dining options, and host cooking classes or challenges that can encourage students to eat more fruits, vegetables and healthy fats. These practical changes can help you take more control of your mental health through small, consistent choices in what you eat every day.

Introduction The various stages of the menstrual cycle affect women in many ways: physically, hormonally, and mentally. Rarely throughout the cycle are females in a state of homeostasis (Mitra et al., 2025). This constant fluctuation in hormone levels and physical symptoms severely affects the lives of these females, as it can result in distraction, lower academic or workplace performance, and negative physical health (Mitra et al., 2025; Bhuvaneswari et al., 2019). The effects aren’t exactly minor. Mitra et al. used this study to examine the physical and mental benefits of participating in a yoga program during the menstrual cycle for college-aged women. The authors suggest that engagement in regular yoga programs will have overall positive benefits on women’s psychophysiological health throughout the typical menstrual cycle. The study was conducted using 82 college-aged females from India who have a normal menstrual cycle and don’t regularly practice yoga. Methods Prospective participants went through an extensive screening process to ensure they met the necessary criteria. Self-report questionnaires were then used to record the various stages of the menstrual cycle, basal body temperature, and menstrual distress symptoms. The Mindful Attention Awareness Scale (MAAS) was also administered. Participants in the experimental group engaged in regular, guided yoga and mindfulness practice, following the same sequence of movements, for a period of three months, and their reported results were then compared to the responses of the control group. Notably, there was no biological measure of hormone or stress levels; the data relied entirely on self-report.

With the highest rates of social networking service use occurring among women aged 18-29, it is important to study the impact of photo-based platforms like Instagram on body image in this demographic (Cohen et al., 2017). Cohen et al.’s study, The relationship between Facebook and Instagram appearance-focused activities and body image concerns in young women, examined 259 Australian women between the ages of 18 and 29 to assess the correlation between appearance-focused social media use and body image concerns such as self-monitoring and thin-ideal internalization. Societal standards often push women toward “self-objectification” to obtain what is prized by society (Cohen et al., 2017). Women may observe current trends and begin comparing themselves to celebrities without consciously considering the negative implications. While these possibilities are troubling, some may be quick to demonize social media for its role in the alarming prevalence of body image issues among young women. This study offers a more specific perspective by comparing appearance-neutral social media use, such as following travel accounts, with appearance-focused social media use, such as monitoring friends’ photos, within this vulnerable demographic.

It’s not a new idea that walking can provide a creative boost. While prior literature focused mainly on more intense aerobic exercise, the authors aimed to test whether a simple and accessible activity like walking could improve creativity both in the moment and shortly afterward. Specifically, the study examined how walking affects divergent thinking (brainstorming) versus convergent thinking (finding a single correct solution), with the goal of identifying an easy method for boosting creativity (Oppezzo & Schwartz, 2014). The study includes four experiments assessing how walking affects creativity. Experiment 1 shows that walking on a treadmill improves divergent thinking. Experiment 2 addresses practice effects and finds that the benefits of walking persist even after participants sit down. Experiment 3 shows that these benefits also occur in outdoor settings. Finally, Experiment 4 provides evidence that walking, rather than simply being outdoors, contributes to the increase in creativity.

Introduction Screen use among adolescents has grown rapidly, and so have concerns about what it's doing to their mental health. According to Santos et al. (2023), using devices on weekdays has been associated with diminished overall mental well-being. Adolescence already carries an increased risk for mental health problems, so it is important to monitor both how much time teens spend on screens and what they're consuming. Excluding schoolwork, media-related activities take up around six to nine hours of an American adolescent's day (Santos et al., 2023). That's a lot of time. This systematic review aimed to highlight the effects of screen exposure on a wide range of mental health aspects in adolescents. These include conduct issues, disorders such as depression, psychosocial difficulties, life satisfaction, and more. The study contributes to our knowledge of how adolescents interact with screens and how increased exposure may affect their well-being.  Methods Santos et al. (2023) followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), meaning the researchers gathered and analyzed existing articles published in the last ten years rather than collecting new data. The methodological quality of each study was determined using the Newcastle-Ottawa Scale. Four reviewers evaluated the studies in pairs, and a fifth reviewer resolved any discrepancies. In total, fifty articles were reviewed, 38 cross-sectional and 12 longitudinal, covering 1,900,447 adolescents. Participants ranged from 10 to 21 years old, and screen time was mostly self-reported.

Introduction Black adolescent boys face unique and serious mental health challenges that are often underaddressed. According to Ribeiro Brown et al. (2022), Black boys are disproportionately exposed to psychosocial stressors such as racial discrimination, community violence, poverty, and attending under-resourced schools. Despite this heightened risk, research on how Black boys seek help and what mental health resources they use remains scarce. Previous research estimates that between 50% and 76.5% of Black youth have unmet mental health service needs. That gap matters. The purpose of this exploratory case study was to examine the types of mental health resources Black high school boys currently use, with the broader goal of informing the development of a tailored mental health education and support program for this population. In this study, mental health resources are broadly defined as any person, platform, tool, or practice that a young person turns to cope with stress and support their emotional wellbeing. The researchers set out to answer one question: What kinds of mental health support resources are Black boys using? Methods Ribeiro Brown et al. (2022) used an exploratory case study design with a qualitative approach, meaning the study focused on in-depth individual and group experiences rather than numerical measurements. The researchers recruited six self-identified Black male high school students from a predominantly Black high school in southeastern Michigan. The participants ranged in age from 15 to 17 years old (mean age = 16.5), with five being high school seniors and one being a sophomore. One participant also identified as Afro-Latino and one as Afro-Caribbean. A Black male PhD-trained researcher led an hour-long focus group over lunch in the fall semester of 2021 to gather data. The focus group questionnaire covered topics like where participants look for information, who they trust for health information, how they handle stress, which social media platforms they use, how they feel about school-based programs, and what qualities would make a person or program trustworthy. The audio recording of the session was transcribed. To find the most common codes and themes, data were evaluated using a Rapid and Accelerated Data Reduction (RADaR) technique in conjunction with traditional text analysis. Results Four major themes emerged from the analysis. The first theme was online resources, including social media (Instagram and Snapchat), websites, and entertainment media. The second theme was community and trusted individuals, with boys reporting that they relied on neighbors, older family members, and community figures who had shared similar life experiences. Participants emphasized that trusted individuals needed to be both relatable and educated. The third theme was self-reliance, where some boys expressed a preference for handling stress independently, reflecting a cultural norm of emotional self-management common among Black adolescents. The fourth theme was additional needs, where participants identified gaps in culturally tailored programs, positive role models, and school support.

The purpose of this study is to understand how daily activities such as meal preparation and cooking can support individuals recovering from severe mental illness (SMI). Individuals with SMI can experience difficulties in daily life, and Garcia and Privott (2023) sought to understand how meal preparation and cooking groups could support the transition to independent community living through occupational therapy. Occupational therapy uses everyday activities to support clients’ physical and mental health. Another goal of the study was to better understand the challenges individuals with SMI face so that more effective interventions can be developed. The study focused on one participant who had experienced long-term institutionalization and later transitioned to independent living.

The highest proportion of people with alcohol disorders are aged between 18 and 29 (Hingson R, Annu Rev), which includes a majority of enrolled university students. Heavy alcohol use and “binge drinking” are also very well documented among college students. Given that universities maintain a reputation for being academically rigorous, there is concern that alcohol misuse could harm academic achievement. Ansari, Stock, and Mills designed the study to assess the associations between five alcohol consumption variables (length of time of last drinking occasion; number of drinks consumed during the last drinking occasion; frequency of alcohol consumption; heavy episode drinking; and problem drinking) and three academic achievement indicators (importance of good grades, performance relative to peers, and module mark). The researchers aimed to determine what type of drinking was most associated with academic outcomes and explore which academic achievement measures were most associated with alcohol consumption.

Undergraduate students often face significant lifestyle shifts during their transition to university, including newfound autonomy and increased social and academic demands, which can lead to poor mental and physical health (Hagedorn et al., 2021). This period is frequently marked by high rates of sleep disruption and the emergence of food insecurity, defined as limited or uncertain access to safe and nutritious food, both of which are linked to decreased academic success and retention. Hagedorn and colleagues (2021) explored the associations between food insecurity, sleep quality, and the frequency of poor mental and physical health days among college students. The study, which used a cross-sectional design, analyzed data from a large sample of 17,686 students across twenty-two higher education institutions in the United States, finding that food-insecure students were significantly more likely to experience poor sleep quality and higher levels of psychological and physical distress than students who ate more nutritious foods. To assess student well-being, researchers administered an online survey to 17,686 college students across twenty-two higher education institutions in the United States. Food security status was measured using the USDA's ten-item Adult Food Security Survey, modified to capture the timeframe since the students began college. Sleep quality was evaluated using the nineteen-item Pittsburgh Sleep Quality Index (PSQI), while mental and physical health were assessed through the Healthy Days Core Module, which tracks the number of days in the past month that health issues interfered with daily activities. Multivariate logistic regression was then used to determine the relationship between food security and these health outcomes, expressed as an Adjusted Odds Ratio (AOR).

Introduction Being a college student in this day and age comes with a plethora of stressors, from academic pressure and financial instability to social expectations and uncertainty about the future. As a result, struggling with anxiety and depression is not uncommon in this environment. At the same time, as online mental health services continue to expand, therapy has become more accessible than ever, allowing students to seek support from the comfort and privacy of their own dorm rooms. Mental health conversations are more visible than ever among young adults, especially on college campuses and social media. However, visibility does not always translate into equal access or willingness to seek help. Gender expectations continue to influence how college students understand emotional struggles, whether they seek professional support, and how they experience mental health care once they receive it. Mental health struggles among college students have become increasingly common in recent years (Bird et al., 2020). Academic pressure, financial stress, social expectations, and uncertainty about the future can all contribute to feelings of anxiety, depression, and emotional burnout. Although mental health conversations have become more normalized, many students still hesitate to seek professional help. Research suggests that stigma and gender expectations continue to play a major role in shaping attitudes toward therapy and mental health services (Bird et al., 2020). Studies consistently show that women are generally more likely than men to seek professional psychological help and to hold more positive attitudes toward therapy (Ang et al., 2004). Researchers have found these gender differences across multiple cultures and age groups, suggesting that the gap is not limited to one specific population. At the same time, these differences are often connected to broader social expectations surrounding masculinity and femininity rather than biology alone. Traditional masculine norms frequently emphasize independence, emotional control, and self-reliance, which can discourage men from openly discussing emotional struggles or asking for help (Courtenay, 2000). According to Will Courtenay’s theory of masculinity and health, many health-related behaviors are tied to how individuals “perform” gender socially (Courtenay, 2000). In this framework, avoiding vulnerability or refusing help can become associated with appearing strong or masculine. Research on college-aged men similarly found that gender stereotypes and masculine beliefs can negatively influence help-seeking behaviors (Juvrud & Rennels, 2017). Men may fear appearing weak, dependent, or emotionally unstable if they pursue therapy or counseling services. Meanwhile, women are often socialized to be more emotionally expressive and open about personal struggles, which may make therapy feel more socially acceptable for them. However, stigma affects both men and women, even if it appears differently. Researchers studying college students found that public stigma and self-stigma are major barriers preventing students from utilizing mental health services (Bird et al., 2020). Public stigma refers to negative societal perceptions about people who seek mental health treatment, while self-stigma occurs when individuals internalize those beliefs and judge themselves negatively for needing help (Bird et al., 2020). Another study found that attitudes toward therapy and stigma often influence help-seeking decisions more strongly than the actual severity of psychological symptoms themselves (Baptista & Zanon, 2017). In other words, even students experiencing serious anxiety, depression, or stress may avoid seeking treatment because of shame, fear of judgment, or discomfort with vulnerability.  The rise of online mental health services has also introduced new conversations surrounding accessibility and comfort. Online counseling offers convenience, privacy, and easier access for students who may feel intimidated by traditional face-to-face therapy (Bird et al., 2020). However, research shows that many college students still view face-to-face counseling more favorably and report stronger intentions to pursue in-person therapy (Bird et al., 2020). While online therapy may reduce certain barriers, stigma and personal attitudes toward mental health treatment continue to influence whether students actually utilize these services. Rather than suggesting that one gender struggles more than another, current research demonstrates that men and women may experience different social pressures surrounding emotional expression and help-seeking. These differences can influence how college students perceive therapy, whether they seek professional support, and how comfortable they feel utilizing mental health services.

Starting college often means a lot of change at once. For many undergraduate students, it is my first time sharing a small space with a roommate. With new academic demands and social pressures, it is common for students to struggle with their mental health, which can affect not only their grades, but also their relationships and overall well-being. In this article, Benjamin R. Meagher and Brynn Anderson from the Department of Psychology at Hope College in Holland, MI, explore how the physical college environment relates to undergraduate students’ mental health. A student’s room on campus has many roles. It is a place to sleep, study, socialize, relax, and simply be alone. Even though dorm rooms come with standard furniture, they still offer a chance for students to personalize the space and express themselves, which can support autonomy and a sense of flourishing. However, imagining a certain ambience for a room does not always mean it becomes reality. Structural limitations, social conflicts, or one’s own ability to decorate and organize space can all interfere. This article focuses on the idea that a room that does not support self-regulation and coping may negatively affect students’ psychological needs. The study examined how students perceive their room’s ambiance and how that perception relates to their well-being. It also looked at how differences between an ideal room and the actual room of ambience may be linked to mental health outcomes such as symptoms of depression and anxiety.  In Study 1, 163 undergraduate students completed a questionnaire about their ideal version of on-campus housing. The ideal space was described as “the space you would want to live in on campus if there was an unlimited amount of time and money to build and personalize it. It is the type of place you would design if you could have anything you want in a room. It fits you like a glove and fulfills your every need.” After this description, participants rated how important certain aspects of the space were, such as relaxation, community, and how inviting it felt, and then were asked whether those same qualities described the feelings their actual rooms created in themselves and in others. The researchers also used established measures to assess depressive and anxiety symptoms, as well as negative and positive effects. Overall, this part of the article focused on whether the idealized version of students’ rooms matched their actual living space, and how that match, or mismatch, influenced their mental health. The results showed that when students’ ideal versions of their dorms were very different from their actual living spaces, they reported more depressive symptoms and higher negative effects. There was no strong relationship between room ambiance and positive affect. This suggests that dorm rooms may function more as spaces that protect students from negative emotions than as spaces that increase positive experiences. Study 2 addressed one of the limits of Study 1 by including roommates. In this second study, 75 roommate pairs, or 150 participants in total, completed the same measures used in Study 1. In addition, participants answered questions about their relationship with their roommate and completed the 44-item Big Five Inventory, which assesses extraversion, agreeableness, conscientiousness, emotional stability, and openness. The results of Study 2 were similar to those of Study 1 in terms of the relationship between mental health and the difference between perceived and ideal room ambience. Again, larger gaps between the real room and the ideal one were linked to more negative mental health symptoms. However, there were no significant findings connecting roommate relationship quality to residents’ mental health. This suggests that, in this study, mental health symptoms were more closely related to students’ own perceptions of their environment than to their relationship with their roommate. The study also found that individuals who described their rooms as high in self-expression, uniqueness, creativity, and pride, but low in spirituality, quiet, organization, productivity, and cleanliness, were more likely to report higher rates of negative mental health symptoms.
