“…However, because we did not monitor sleep under controlled laboratory conditions, we cannot exclude the possibility that individual participants slept poorly or not at all before the measurements and did not communicate this with us. In addition, emotional stress can also affect food intake [64]. However, it must be considered that all participants were tested on three different days at least two weeks apart, so it is questionable as to whether such a transient variable can explain our significant results.…”

Obesity and mobile phone usage have simultaneously spread worldwide. Radio frequency-modulated electromagnetic fields (RF-EMFs) emitted by mobile phones are largely absorbed by the head of the user, influence cerebral glucose metabolism, and modulate neuronal excitability. Body weight adjustment, in turn, is one of the main brain functions as food intake behavior and appetite perception underlie hypothalamic regulation. Against this background, we questioned if mobile phone radiation and food intake may be related. In a single-blind, sham-controlled, randomized crossover comparison, 15 normal-weight young men (23.47 ± 0.68 years) were exposed to 25 min of RF-EMFs emitted by two different mobile phone types vs. sham radiation under fasting conditions. Spontaneous food intake was assessed by an ad libitum standard buffet test and cerebral energy homeostasis was monitored by 31phosphorus-magnetic resonance spectroscopy measurements. Exposure to both mobile phones strikingly increased overall caloric intake by 22–27% compared with the sham condition. Differential analyses of macronutrient ingestion revealed that higher calorie consumption was mainly due to enhanced carbohydrate intake. Measurements of the cerebral energy content, i.e., adenosine triphosphate and phosphocreatine ratios to inorganic phosphate, displayed an increase upon mobile phone radiation. Our results identify RF-EMFs as a potential contributing factor to overeating, which underlies the obesity epidemic. Beyond that, the observed RF-EMFs-induced alterations of the brain energy homeostasis may put our data into a broader context because a balanced brain energy homeostasis is of fundamental importance for all brain functions. Potential disturbances by electromagnetic fields may therefore exert some generalized neurobiological effects, which are not yet foreseeable.

“…However, in our earlier study the consumption of whole grain products was lower in the most stressed individuals compared to the least stressed (6) . Additionally, López-Ceperon et al (7) reported that psychological distress was connected to a lower intake of fibre-rich foods, including whole grains. It is essential to note that the effect size of our analysis on whole grain consumption and GHQ scores was small, which may partly explain the lack of significance in our sampling.…”

“…However, the causality between whole grain-rich diet and mental health, and the mechanisms underlying their associations are still unclear. On the other hand, psychological distress can affect food choices and thus the consumption of whole grains, indicating a reverse causation (6,7) . By understanding this association and acknowledging how these alterations in food choices may subsequently affect nutrient intake, it emphasizes the significance of evaluating the association between psychological distress and food choices.…”

This study aimed to investigate whether psychological distress, whole grain consumption, and tryptophan metabolism are associated in participants undergoing weight management intervention. Seventy-nine women and men (mean age 49.7 ± 9.0 years; BMI 34.2 ± 2.5 kg/m2) participated in a 7-week weight-loss period (WL), and in a 24-week weight maintenance intervention period (WM). Whole grain consumption was measured using 4-day food diaries. Psychological distress was assessed with the General Health Questionnaire-12 (GHQ), and participants were divided into three GHQ groups based on the GHQ scores before WL. Tryptophan metabolites were determined from the participants’ fasting plasma using liquid chromatography-mass spectrometry. GHQ scores were not associated with the whole grain consumption. A positive association was observed between the whole grain consumption and indole propionic acid (IPA) during the WM (p = 0.033). Serotonin levels were higher after the WL in the lowest GHQ tertile (p = 0.033), while the level at the end of the WM was higher compared to other timepoints in the highest GHQ tertile (p = 0.015 and p = 0.001). This difference between groups was not statistically significant. Furthermore, levels of several tryptophan metabolites changed within the groups during the study. Tryptophan metabolism changed during the study in the whole study group, independently from the level of psychological distress. The association between whole grain consumption and IPA is possibly explained by the effects of dietary fibre on gut microbiota. This broadens the understanding of the pathways behind the health benefits associated with the intake of whole grains.

“…This study examined the role psychological variables (stress, emotions and mental state) play students' consumption of healthy meals. Scholars have pointed out that academic stress influences university students' food intake to varying degrees (Chacón-Cuberos et al, 2019;Jiang et al, 2019;López-Cepero et al, 2021;Pendry et al, 2021;Whatnall et al, 2019). Mood and guilt have also been revealed as psychological determinants of food choice among adolescents (Mahmoud & Grigoriou, 2022;Michels et al, 2018;Schwartz et al, 2018), but the specific extent to which the influence is felt on their food consumption was barely highlighted.…”

INTRODUCTION: Many higher education students indulge in risky eating behaviours which tend to affect their physical, psychological and academic health. Previous studies have tried to understand the trend in students' eating patterns without paying adequate attention to contributing factors. PURPOSE: This study evaluated the influence of selected psychological variables on the consumption of balanced diets among students in two public universities in Calabar Metropolis, Nigeria. METHODOLOGY: A research question was posed, and a formulated hypothesis to guide the study. The study adopted the descriptive survey research design. A total of 12,530 faculty of education students spread across two public universities in Calabar Metropolis constituted the population of this study. A sample of 125 students was randomly selected through the stratified technique. A four-point questionnaire was used for data collection after validation by experts. Descriptive statistical measures such as mean, standard deviation, and percentages answered the research question. The null hypothesis was tested at the .05 level of significance using the one-sample t-test analysis. RESULTS: Findings revealed that the influence of psychological variables (such as stress, emotions, and mental state) on students' consumption of balanced diets is not significantly low. RECOMMENDATIONS/CLASSROOM IMPLICATIONS: Based on the findings of this study, it was recommended that students cultivate the habit of always eating quality meals rich in nutrients, irrespective of their psychological state, to maintain a healthy life.
