“…Hence, based on the theory of “comfort foods”, the consumption of these kinds of foodstuff, rich in sugar and fats, could represent an escape coping strategy due to the emotional component of eating and the rewarding effects of this type of food, reducing perceived stress [28]. Recent research indicates that leptin may play a role as a mediator between psychosocial stress and emotional eating characteristic of stressed individuals [29]. Specifically, chronic stress induces high cortisol levels and, in turn, high leptin concentrations due to resistance mechanisms associated with greater intake of comfort food [29].…”

The prevalence of bullying has increased dramatically during recent years, with numerous negative consequences for the health and quality of life of bullied adolescents. Although negative psychological consequences of this type of situation have been widely investigated, no previous research has evaluated the effects of bullying victimization on dietary habits, and its relationship with psychological outcomes, such as depression. For this reason, the main aim of the present study was to evaluate the association between bullying, dietary habits, and depression in a sample of 527 Spanish adolescents. The results obtained showed that being bullied was correlated negatively with healthy dietary habits and positively with depression. Moderation analysis revealed dietary habits as moderator of the association between bullying and depression. These results underline the relevance of diet in the phenomenon of bullying, especially in victims, as could be related to the high levels of depression characteristic of this population. The inclusion of nutritional education in intervention programs oriented to victims of bullying might significantly improve their efficacy, reducing depression levels.

“…The consumption of these type of foods has demonstrated to activate the brain reward circuitry [23], alleviating the stress perception momentarily but promoting the development of an emotional-eating behavior, a behavioral pattern classically related to poorer health outcomes [23]. The biological mechanisms that have been proposed to explain this association are based on the effects of the high cortisol secretion derived from the stress of social isolation [24]. High cortisol release has been related to high leptin concentrations, due to resistance mechanisms [24].…”

Low Adherence to the Mediterranean Diet in Isolated Adolescents: The Mediation Effects of Stress

et al. 2018

View full text Add to dashboard Cite

Loneliness perception during adolescence has been increased dramatically in recent years. Changes in lifestyle and difficulties in social interaction could explain this increased phenomenon. As described in previous research, this fact has been associated with the development of high stress levels and dysfunctional lifestyles, in which eating habits play a main role. In this regard, loneliness has been classically associated with poor eating habits, fundamentally the consumption of processed food with little nutritional value. However, the relationship between loneliness and healthy eating patterns, such as the Mediterranean Diet (MD), has not been previously analyzed. The main aim of the present study was to identify the relationship between perceived loneliness, stress, dietary habits, and adherence to the MD in a sample of 527 Spanish adolescents. The obtained results show a significant association between high perceived loneliness and high stress levels with lower MD adherence. Hence, adolescents with high perceived loneliness exhibit poor dietary habits in comparison to those counterparts with low perceived loneliness. Mediation analyses demonstrated an indirect effect of the loneliness on adherence to the MD through the mediation effect of stress. These findings point out a possible mechanism that underlies the classic association between loneliness and health deterioration, based on a poor adherence to a healthy dietary pattern, such as the MD.

“…In this study, most older adults who thought their emotional state affected their food consumption (45.5% of females, 66.7% of males) ate less under emotional distress, while during times of emotional happiness their well-being increased, as did their food intake (25.0% of females, 18.2% of males). This is an interesting finding as most studies have reported increased cortisol because of stress causes leptin resistance, leading to increased food consumption [ 14 15 ]. In addition to emotional changes, changes in food consumption depend on access to certain foods during different seasons [ 16 17 ].…”

BACKGROUND/OBJECTIVESAvailable data suggest that seasonal changes may influence the nutritional status and overall health of elderly individuals. Therefore, this study was conducted to investigate the effects of seasonal changes and related factors on energy and nutrient intake of older adults.SUBJECTS/METHODSIndividuals aged 65 years or over were prospectively enrolled in this single-center study (male: 11, female: 20). Data were collected between May 2013 and February 2014 during winter, spring, summer and autumn. Food consumption and biochemical parameters were taken during each season to assess the seasonal nutrition status of the elderly. Upon analysis of biochemical parameters (retinol, vitamin D and vitamin C), an high-performance liquid chromatography device was utilized whereas an Immulite 2000 device was utilized during analysis of serum folic acid and parathyroid hormone.RESULTSFruit, fat, egg and bread consumption varied seasonally in males and females (P < 0.05). During winter, daily energy intake was found to be greater than in other seasons in males (557 kcal) and females (330 kcal) (P < 0.05). Additionally, carbohydrates, vegetable protein, n-3 fatty acid and sodium intake increased in winter, while the n-6/n-3 ratio increased in summer among males (P < 0.05). Dietary fiber and sodium intake in winter, vitamin C, iron and zinc intake in spring, and cholesterol, retinol, vitamin D and niacin intake in autumn were found to be higher in females when compared to other seasons (P < 0.05). Serum parathyroid hormone level was higher in winter, and vitamin D level was higher in autumn in both genders (P < 0.05). In males, blood folic acid level was higher in winter, while vitamin C level was higher in females, and there was no seasonal variation in retinol concentration (P < 0.05).CONCLUSIONFood consumption and biochemical parameters showed significant seasonal variations in older adults. It is not clear if nutrition plans in older adults will benefit from consideration of seasonal changes in eating habits.
