Emotional Eating: The Perpetual Cycle Of Mood-Food Influence ✓ Solved

Emotional Eating: The Perpetual Cycle of Mood-Food Influence

This is a literature review I wrote for Psychology 109 / Research Methods I. It received an A. The assignment was to read a variety of assigned articles related to the topic of food and mood, as well as several articles on the topic that we found on our own. Then, we were to write a literature review in which we identified a theme from our readings on the topic and crafted a thematically organized essay, drawing on the articles we read. Unlike an annotated bibliography, in which the articles cited are presented in chronological order without an overarching theme connecting them, a literature review synthesizes the findings from multiple studies and has a thesis statement highlighting a general theme of the research that emerges from the studies and will be discussed throughout the review.

Also, unlike a research report, a literature review is not organized into discrete introduction, methods, results, and discussion sections. Its organization is much more flexible, as it revolves around the themes being discussed from the literature. I have annotated places in this paper that highlight some key features of literature reviews. I have omitted some sentences that contained mostly methodological details and data from several of the sections. However, I have left the introduction and conclusion completely intact to provide an example of the general structure and content of these sections of a literature review.

While the bold headings above each section are not necessary in a literature review, they are included here to illustrate what each section is addressing and the thematic organization of the paper.

Introduction

It is no secret that obesity is a major health concern in the U.S., and stress and other negative emotions may be contributing to the problem. There has been much research on how the food we eat affects our physical health, but comparatively little research on the relationship between our eating behavior and emotional states. Studies have found that there is some science behind the tendency to drown our sorrows in a pint of Ben & Jerry’s (Oliver & Wardle, 1999; Epel et al., 2001). Research has also highlighted gender differences in the ways men and women use eating to cope with stress (Christensen & Brooks, 2006). The relationship between food and mood runs in the reverse direction as well, as eating behavior appears to have some bearing on subsequent moods: higher consumption of calories, saturated fat, and sodium are associated with negative moods one to two days later (Hendy, 2012).

Influence of Mood on Eating Behavior

Our emotional states play a significant role in the quantity and types of food we choose to eat. Studies have examined the self-reported eating behaviors of male and female undergraduate students in response to stress. Oliver and Wardle (1999) administered questionnaires assessing beliefs about stress effects on eating. Their results showed that about 42% of participants reported increasing overall food intake under stress, while 37% reported decreasing it. Notably, 73% reported increased consumption of snack-type foods like sweets and chips when stressed. These findings suggest stress influences eating habits, possibly because snack foods are calorically dense, quick to eat, and can boost serotonin levels, which improve mood and relieve stress (Oliver & Wardle, 1999).

However, these studies have limitations. Oliver & Wardle (1999) did not define stress operationally, nor did they measure actual behavior, relying instead on beliefs about hypothetical responses. This gap hinders definitive conclusions about real-life eating. Another study by Epel et al. (2001) measured salivary cortisol levels, a stress hormone, in premenopausal women. Results indicated that higher cortisol levels correlated with increased intake of calories and sweet, high-fat snacks post-stress, suggesting cortisol may drive stress-induced overeating.

Gender Differences

Additional research highlights gender differences in responses to emotional states concerning food intake. Christensen and Brooks (2006) explored predicted eating behaviors under happiness or sadness. Women tend to report more cravings and increased intake of sweet, high-fat foods when distressed, possibly because these foods boost serotonin and act as coping mechanisms. Conversely, men report less craving and may use other strategies such as exercise to cope with distress (Christensen & Brooks, 2006). Oliver and Wardle (1999) also found women and dieters more likely to consume snack foods in response to stress, possibly due to concerns about body image and restrictive eating when not stressed.

Impact of Eating Behavior on Later Moods

The food we consume also affects subsequent moods, forming another part of the bidirectional relationship. Hendy (2012) conducted a seven-day naturalistic study with undergraduates, finding that higher consumption of calories, saturated fats, and sodium often preceded negative moods by one or two days. The findings support the idea that stress-induced eating may create a vicious cycle: temporary relief from stress through comfort foods leads to feelings of guilt or depression later, prompting further consumption of these foods (Hendy, 2012).

Chronic Stress and the Stress Response Network

Chronic stress and emotional eating can alter the body's stress regulation system, potentially leading to obesity. Dallman, Pecoraro, and la Fleur (2005) studied rats exposed to stress, which initially showed high corticosterone (stress hormone) levels associated with food drives. Over time, continual stress and comfort food consumption muted the hypothalamo-pituitary-adrenal (HPA) axis activity, reducing corticosterone release and creating a dampened stress response. Similar findings in humans by Tomiyama et al. (2011) indicated that chronically stressed women exhibited lower cortisol secretion, implying diminished HPA activity.

This feedback loop, where comfort foods temporarily dampen stress responses, results in individuals relying more on these foods, which over time contributes to weight gain and obesity. These studies collectively suggest that emotional eating and stress response dysregulation are intertwined, influencing health outcomes.

Implications and Future Directions

The research underscores that comfort foods serve as a temporary emotional fix but perpetuate negative health cycles. Understanding the psychological and physiological mechanisms behind emotional eating is crucial for developing healthier coping strategies. Alternative methods like mindfulness and exercise could serve as effective interventions to break the stress-eating cycle. Moreover, targeted research exploring effective stress management tools and their integration into daily life is essential for public health initiatives aimed at reducing obesity linked to emotional eating (Dallman et al., 2005; Tomiyama et al., 2011).

Conclusion

In summary, the body and mind are interconnected in complex ways that influence eating behaviors and emotional states. The temporary relief provided by comfort foods can lead to a cycle of repeated eating in response to stress, with detrimental effects over time. Particularly among women, these behaviors are linked to weight gain and obesity, which pose significant health risks. Future research should focus on developing effective interventions to manage stress without relying on high-calorie comfort foods, thereby improving both emotional health and physical well-being. Such efforts could significantly mitigate the obesity epidemic attributable, in part, to emotional eating patterns.
