Relationship of increased fruit/vegetable intake with reduced consumption of sweets: Psychological mechanisms and associated weight loss in women within behavioral obesity treatments. Health Care Women Int 2024:1-21. [PMID: 38832937 DOI: 10.1080/07399332.2024.2359555] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Accepted: 05/21/2024] [Indexed: 06/06/2024]
Abstract
Although an increase in fruit and vegetable (FV) consumption in adults might result in reductions in their intake of sweets, there has been minimal direct testing of this. Women participated in 6-month community-based obesity treatment conditions where either their psychological skills development (n = 66) or knowledge regarding healthful eating and exercise (n = 39) was emphasized. Improvements in FV and sweets intake, eating-related self-regulation, self-efficacy for controlled eating, and negative mood were significantly more pronounced in the psychological skills group participants. Together, participants' change in self-regulation, self-efficacy, and mood significantly mediated the relationship of their changes in FV and sweets. Within simple mediation analyses, participants' changes in self-efficacy and negative mood were significant mediators, and their treatment group membership moderated effects on sweets. We provided suggestions for future treatments based on the present findings.

Eur J Nutr 2024; 63:1071-1088. [PMID: 38300292 PMCID: PMC11139700 DOI: 10.1007/s00394-023-03311-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Accepted: 12/18/2023] [Indexed: 02/02/2024]
Abstract
PURPOSE The aim of the present study was to examine the acute and chronic effects of wild blueberry supplementation on mood, executive function, and serum biomarkers of neuroplasticity, inflammation, and oxidative stress in emerging adults with moderate-to-severe depressive symptoms. METHODS In this double-blind trial, 60 emerging adults (Mage = 20.0 years, 32% male) with self-reported depressive symptoms were randomly assigned to receive a single blueberry drink (acute phase), followed by 6 weeks of daily blueberry supplementation (chronic phase), or a matched placebo drink. The primary outcome was Beck Depression Inventory-II (BDI-II) scores at 6-week follow-up. Further measures included momentary affect (PANAS-X) and accuracy on an executive function task. The data were analyzed using ANCOVAs adjusted for baseline values, sex, and habitual fruit and vegetable intake. Estimated marginal means were calculated to compare the treatment arms. RESULTS The blueberry drink significantly improved positive affect (p = 0.026) and executive function (p = 0.025) at 2 h post-ingestion, with change scores being positively correlated in the blueberry group (r = 0.424, p = 0.017). However, after six weeks of supplementation the reduction in BDI-II scores was greater in the placebo group by 5.8 points (95% CI: 0.8-10.7, p = 0.023). Generalized anxiety and anhedonia also decreased significantly more in the placebo group. No significant differences were found for any of the biomarkers. CONCLUSIONS Six weeks of wild blueberry supplementation were inferior to placebo in reducing depressive symptoms. Nevertheless, the correlated improvements in positive affect and executive function after a single dose of blueberries point to a beneficial, albeit transient, psychological effect. These contrasting results suggest a biphasic, hormetic-like response that warrants further investigation. TRIAL REGISTRATION NCT04647019, dated 30 November, 2020.

Abstract
The burden of disease attributable to mental health is expected to rise in the coming decades. Poor nutritional status is considered a modifiable risk factor for general mental health. In fact, nutrition interventions are now accepted as a core strategy in mental healthcare to combat physical health inequalities and life-expectancy gap in people with certain psychiatric disorders. However, most psychiatrists are not familiar with evidence for the potential therapeutic benefits of diet in psychiatric illness, and this may be related to sparse nutrition education for physicians. Thus, there is a need to integrate nutritional management in psychiatric practice, but there is a gap in medical education that would support this practice. Here, we discuss evidence for and challenges in 1) assessing diet quality in psychiatric illness, 2) recommending improvements in diet quality and specific dietary patterns in psychiatric illness, and 3) recommending dietary supplements in psychiatric illness. This discussion serves as a call to develop nutrition curricula within psychiatry residency programs.

Br J Nutr 2024; 131:1384-1396. [PMID: 38073290 PMCID: PMC10950451 DOI: 10.1017/s0007114523002787] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2023] [Revised: 11/09/2023] [Accepted: 11/20/2023] [Indexed: 01/23/2024]
Abstract
Vitamin C-rich foods can improve mood; however, the timecourse of these benefits is unknown. This study utilised intensive longitudinal smartphone surveys from a three-armed placebo-controlled trial to determine mood-related changes following supplementation with vitamin C (250 mg tablet/d), kiwifruit (2 SunGold™ kiwifruit/d) or a placebo (1 tablet/d). Secondary data were analysed from the KiwiC for Vitality trial (Trial ID: ACTRN12617001031358). Adults (n 155, 63 % female, aged 18-35 years) with low plasma vitamin C (<40 μmol/l) completed a 14-d lead-in, 28-d intervention and 14-d washout. Participants self-reported vitality (SF-36), mood (POMS total mood disturbance), flourishing (flourishing scale), sleep quality, sleep quantity and physical activity every second day using smartphone surveys. Plasma vitamin C, measured fortnightly, reached saturation after 2 weeks of vitamin C or kiwifruit supplementation. Kiwifruit supplementation improved vitality and mood within 4 days, peaking around 14-16 days, and improved flourishing from day 14. Vitamin C marginally improved mood until day 12. Incremental AUC analyses revealed significant overall effects of kiwifruit consumption on vitality and mood compared with placebo, which were stronger than effects for vitamin C tablets, but attenuated when adjusting for covariates. Sensitivity analyses of participants with low baseline vitamin C status revealed improved mood (vitamin C and kiwifruit) and flourishing (kiwifruit only). This is the first study to use intensive smartphone surveys to model the day-to-day timecourse of mood-related states following vitamin C intervention and highlights the value of using smartphone surveys to reveal the temporal changes in mood-related outcomes following nutrient supplementation.

Abstract
Associations between subjective well-being (SWB) and dietary habits, employment status, and habitual activities are increasingly capturing the focus of researchers as well as policymakers worldwide. This study aimed to explore these associations in a sample of the population in Greece and Cyprus via an online survey. In total, 936 questionnaires (470: Cyprus, 466: Greece) were analyzed to study the associations between the Mediterranean Diet (MD) (using the 14-item MEDAS score, (14-MEDAS)), subjective well-being (SWB), and several socioeconomic factors. Key remarks of this survey highlight the positive impact of MD adherence on some well-being items. Namely, statistically significant differences were found on the following items: Satisfied with life (p < 0.001), Life worthwhile (p < 0.001), Feeling happy (p < 0.001), worried (p = 0.005), and depressed (p = 0.001), when comparing Low MD adherence (14-MEDAS < 5) to High MD adherence (14-MEDAS > 10). Other lifestyle habits such as spending time with friends and family, spending time in nature, and habitual physical activity were associated with aspects of SWB such as Life satisfaction, Life worthwhile, Feeling happy, and energetic. The findings support adherence to the MD, since it is associated with higher life satisfaction and self-reported happiness in this sample and should be considered when developing health policies on well-being.

Abstract
Health behaviors (physical activity and healthy eating) can be an essential part of everyday work life and are relevant for employees' affective states. Many worksite interventions, including goal-striving approaches, have been developed to promote health behavior at work. However, these approaches often neglect that making progress with respect to health-behavior goals necessarily takes place during workday episodes, so that work tasks are accomplished simultaneously. In our study, we aim to advance the understanding of how health-behavior goal progress is facilitated and how reflecting on it evokes affective states-taking into account simultaneous pursuit of work-task progress. We collected daily diary data from 205 employees on 1399 days. Analyses showed that goal importance positively predicted health-behavior goal progress, which in turn positively predicted pride and negatively predicted shame at the end of the workday. The negative relation between health-behavior goal progress and shame was stronger on days with low work-task progress, implying compensatory effects. Work-task progress did not moderate the relation between health-behavior goal progress and pride. We discuss the theoretical and practical relevance of integrating research on multiple goal striving when promoting health behavior in daily work life by means of goal-striving techniques.

Abstract
AIMS This study aims to investigate the association between dietary behaviours, overweight/obesity, and mental health and well-being among Swedish adolescents. METHODS Data from the 2017/2018 Health Behaviour in School-aged Children (HBSC) survey of 3692 adolescents aged ≈11, ≈13, and ≈15 years was analysed. We evaluated the prevalence and association of dietary behaviours, characterised by daily intake of fruits and vegetables, consumption of sugar-sweetened beverages (SSBs) and sweets once per week, and daily consumption of family meals and breakfast, with socioeconomic and demographic factors. Multivariate logistic regression models (adjusted and unadjusted) were then used to examine the relationship between dietary behaviours, overweight/obesity, and mental health and well-being including psychosomatic complaints, life satisfaction, and school-related pressure. RESULTS Boys were more likely to eat breakfast and have meals together with their family than girls, but their fruit and vegetable intake was lower compared to girls. Adolescents with lower socioeconomic status (low family affluence, families perceived 'not well-off' and two unemployed parents), single-parent households and twoforeign born parents were more likely to engage in poorer dietary behaviours. Daily breakfast, family meals, fruit and vegetable intake were positively associated with mental health and well-being. Specifically, daily family meals were linked to higher life satisfaction, fewer psychosomatic complaints, and reduced school-related pressure. Breakfast emerged as a beneficial dietary habit, associated with higher life satisfaction, and a lower likelihood of psychosomatic complaints, school-related pressure, and overweight/obesity. Fruit and vegetable consumption was consistently associated with better mental health and well-being while associations between SSBs and sweets were mixed. CONCLUSIONS Improving mental health and well-being, along with tackling the rising rates of mental illness and challenges related to overweight/obesity in adolescents constitute key public health priorities. Implementing policies that promote the intake of fruits and vegetables, reducing the consumption of SSBs and sweets, and emphasizing the value of having breakfast and sharing family meals could offer a cost-effective public health intervention.

Abstract
Nutrition and diet quality play key roles in preventing and slowing cognitive decline and have been linked to multiple brain disorders. This review compiles available evidence from preclinical studies and clinical trials on the impact of nutrition and interventions regarding major psychiatric conditions and some neurological disorders. We emphasize the potential role of diet-related microbiome alterations in these effects and highlight commonalities between various brain disorders related to the microbiome. Despite numerous studies shedding light on these findings, there are still gaps in our understanding due to the limited availability of definitive human trial data firmly establishing a causal link between a specific diet and microbially mediated brain functions and symptoms. The positive impact of certain diets on the microbiome and cognitive function is frequently ascribed with the anti-inflammatory effects of certain microbial metabolites or a reduction of proinflammatory microbial products. We also critically review recent research on pro- and prebiotics and nondietary interventions, particularly fecal microbiota transplantation. The recent focus on diet in relation to brain disorders could lead to improved treatment outcomes with combined dietary, pharmacological, and behavioral interventions.

Abstract
This study investigated how broader parental factors including parental happiness, parental play engagement, and parenting stress are related to Korean children's happiness and weight status across three years via indirect pathways through the children's energy-related behaviors of healthy and unhealthy food intake, physical activity, and screen time. Data from 1551 Korean parent pairs and 7-year-old children in the Panel Study on Korean Children were analyzed. A path analysis and gender-based multi-group analysis were conducted. Maternal happiness was negatively related to child screen time. Maternal play engagement showed positive concurrent associations with child healthy food intake and physical activity and negative associations with screen time. Maternal parenting stress was negatively related to child healthy eating. There was one significant finding related to fathers' role on children's energy-related behaviors, happiness, and weight status: the positive association between parental happiness and boys' unhealthy food intake. Child screen time was positively related to child weight status and negatively to child happiness at each age. Broader maternal parenting factors can serve as a protective factor for childhood happiness and weight status in 7-to-9-year-olds through being associated with a reduction in child screen time.

Abstract
Eating healthily in terms of fruit and vegetable consumption has beneficial effects for employees and their organisations. Yet, we know little about how employees' eating behaviour develops over longer periods of time (trajectories) as well as about how subgroups of employees in these trajectories differ (trajectory classes). Gaining such insights is critical to understand how employees address healthy eating recommendations over time as well as to develop individualised interventions that also consider the development of healthy eating (i.e. improvement versus impairment beyond mean levels). We analysed panel data (Longitudinal Internet Studies for the Social Sciences) from 1054 employees by means of growth mixture modelling. Our analyses revealed three relevant classes of healthy-eating trajectories: a favourable trajectory class, an unfavourable trajectory class and a strongly improving trajectory class. Furthermore, unfavourable healthy-eating trajectories were especially critical with respect to impaired psychological well-being. Specifically, we found robust results for impaired positive and negative affects, but not for self-esteem, in the unfavourable trajectory class. We discuss limitations and implications of these findings, thereby encouraging research and practice to further consider such fine-grained approaches (i.e. focusing on subgroups within a larger population) when addressing healthy-eating promotion over time.

Can happiness be reliably increased? Thousands of studies speak to this question. However, many of them were conducted during a period in which researchers commonly "p-hacked," creating uncertainty about how many discoveries might be false positives. To prevent p-hacking, happiness researchers increasingly preregister their studies, committing to analysis plans before analyzing data. We conducted a systematic literature search to identify preregistered experiments testing strategies for increasing happiness. We found surprisingly little support for many widely recommended strategies (e.g., performing random acts of kindness). However, our review suggests that other strategies-such as being more sociable-may reliably promote happiness. We also found strong evidence that governments and organizations can improve happiness by providing underprivileged individuals with financial support. We conclude that happiness research stands on the brink of an exciting new era, in which modern best practices will be applied to develop theoretically grounded strategies that can produce lasting gains in life satisfaction.

Abstract
Introduction This paper reports on the effects of a 9-week vitality training that employed behaviour-change techniques and was evaluated using a randomised controlled trial (RCT) in three large companies based in the Netherlands. Methods A total of 84 adult employees from three participating organisations in the Netherlands were enrolled in the study. A parallel group RCT design was employed and participants were assigned using individual random assignment to either an intervention (n = 38) or a waitlist control group (n = 46). The intervention consisted of a 9-week vitality training employing the behaviour-change techniques of self-persuasion, implementation intentions, and self-efficacy, which was delivered in-house over five fortnightly 2-hour sessions. Primary outcomes (i.e., reported energy and stress) and secondary outcomes (i.e., reported daily life satisfaction and work capacity) were assessed prior to, immediately after, and 3 months following the intervention. Results A mixed MANOVA revealed a significant interaction effect between treatment group and time period for the combination of reported energy, stress, daily life satisfaction, and work capacity. Subsequent univariate ANOVAs revealed significant interactions between treatment group and time period for reported energy, stress, and daily life satisfaction; however, not for reported work capacity. Improvements in outcomes were observed for both groups following their completion of the vitality training; however, not all improvements reached statistical significance. Reported self-efficacy regarding managing work-life balance was found to mediate the relationship between the effects of the intervention and reported energy; however, such an effect was not found for stress. Discussion An intervention drawing upon evidence-based behaviour-change techniques shows promise for improving indicators associated with burnout; although, it is recommended that in future research a larger-scale evaluation be conducted over a longer time period with an active control group to establish effectiveness.Clinical trial registration: https://www.anzctr.org.au/, ACTRN12622001268730.

Abstract
Associations between fruit and vegetable (FV) consumption and mental health are suggested, largely from observational studies. This systematic review aimed to identify and summarise all published controlled intervention studies investigating the effects of FV consumption on mental health in adults. Four academic databases (Medline, PsycINFO, PubMed, Web of Science) were searched on 16 September 2022, over all years, for studies that used an intervention design; included FV consumption; included an appropriate non-FV-consumption control; used a validated measure of mental health and were conducted in healthy adults or adults with solely a depressive or anxiety-related condition. Study details were tabulated and combined using meta-analyses. Risk of bias was assessed using the domains of the Cochrane Collaboration. Six studies, enrolling 691 healthy adults and reporting on one or more mental health outcomes, were found. Meta-analyses found small and imprecise effects of FV consumption for: psychological well-being (4 studies, 289 participants) standardised mean difference (SMD) = 0·07 (95 % CI -0·17, 0·30), P = 0·58, I2 = 0 %; depressive symptomology (3 studies, 271 participants) SMD = -0·15 (95 % CI -0·40, 0·10), P = 0·23, I2 = 47 % and anxiety-related symptomology (4 studies, 298 participants) SMD = -0·15 (95 % CI -0·39, 0·08), P = 0·20, I2 = 71 %. Some benefit for psychological well-being was found in change-from-baseline data: SMD = 0·28 (95 % CI 0·05, 0·52), P = 0·02, I2 = 0 %. Risk of bias was high in many studies. Limitations include the consideration only of published studies and stem from the studies found. Given the few, limited studies available and the small size of effects, stronger evidence is needed before recommending FV consumption for mental health.

Abstract
BACKGROUND In Australia, women report higher rates of depressive symptoms than men. Research suggests that dietary patterns rich in fresh fruit and vegetables could protect against depressive symptoms. The Australian Dietary Guidelines suggest that consuming two servings of fruit and five serves of vegetables per day is optimal for overall health. However, this consumption level is often difficult for those experiencing depressive symptoms to achieve. AIMS This study aims to compare diet quality and depressive symptoms in Australian women over time using (I) two serves of fruit and five serves of vegetables per day (FV7), and (ii) two serves of fruit and three serves of vegetables per day (FV5). MATERIALS AND METHODS A secondary analysis was conducted using data from the Australian Longitudinal Study on Women's Health over 12 years at three time points 2006 (n = 9145, Mean age = 30.6, SD = 1.5), 2015 (n = 7186, Mean age = 39.7, SD = 1.5), and 2018 (n = 7121, Mean age = 42.4, SD = 1.5). RESULTS A linear mixed effects model found, after adjusting for covarying factors, a small significant inverse association between both FV7 (b = -.54, 95% CI = -.78, -.29) and FV5 (b = -.38, 95% CI = -.50, -.26) in depressive symptoms. DISCUSSION These findings suggest an association between fruit and vegetable consumption and decreased depressive symptoms. The small effect sizes indicate caution should be taken in interpreting these results. The findings also suggest that current Australian Dietary Guideline recommendations need not be prescriptive to two fruit and five vegetables for impact on depressive symptoms. CONCLUSIONS Future research could evaluate reduced vegetable consumption (three serves per day) in identifying the protective threshold for depressive symptoms.

Abstract
Background Relatively little data describe how diet and food choices impact trainee well-being despite evidence that diet impacts both physical and mental health. The objective was to describe food options available to emergency medicine (EM) residents when on duty. Methods A survey utilizing closed-ended, binary, rank-order responses was developed by experts in graduate medical education and wellness; it was piloted, revised, and then electronically distributed to 211 EM residency programs over 2 weeks in 2021. The program director (PD) or associate PD was invited to participate. Results A total of 114 EM programs participated (54%). The primary teaching site included 43 community hospitals, 23 county hospitals, and 48 university hospitals. Resident access to an onsite hospital cafeteria was most common (97%); other onsite options were vending machines (87%), fresh food fridges (34%), national chains (32%), local restaurants (25%), food trucks (30%), and farmer's markets (11%). More than one-third (38%) reported that onsite options did not include healthy food, 26% reported being dissatisfied with onsite food, and 35% rarely or never purchased food onsite. Most programs (89%) do not have a dedicated "meal break" for residents while on duty. Few residency programs include diet or nutrition classes or counseling. When programs sponsor meals during residency events, nutritional value and dietary considerations were ranked less important than cost of food and convenience. Conclusions Access to healthy food options is not always available during scheduled resident work hours, and dedicated meal breaks are infrequent. These data should inform institutional initiatives to improve the health and well-being of resident physicians.

Abstract
The present review investigates the complex associations between children's affective states, body perceptions, and eating habits, thus providing crucial insights for potential health interventions. Following PRISMA guidelines, three databases were searched for peer-reviewed studies exploring the relationship between eating habits, emotional states, and body image perceptions in a population of children (5 to 11 years old). A total of seven articles were included. Our findings revealed a pattern of associations between negative emotional states, like anxiety and depressive feelings, and maladaptive eating behaviors. Additionally, explicit influences from parental feeding practices, peer pressure, socioeconomic factors, and children's body perceptions were observed to shape eating habits, with a pronounced tendency among older girls towards dieting and food preoccupation. Our results underline the intertwining nature of age, gender, and emotional states. Furthermore, our findings accentuate the urgency for comprehensive interventions that acknowledge and address the complex interplay of emotional, familial, and socioeconomic factors alongside children's body image perceptions. The criticality of continued research, particularly ones employing longitudinal designs and diverse demographic samples, is highlighted as we strive to understand and navigate such multifaceted relationships to enhance children's health and well-being.

Abstract
BACKGROUND The first two years of life is a vital period for promoting optimal growth, development and health. The lifelong nutritional habit and overall health of children is influenced by their early age feeding practice. Ethiopia is among the top five countries in Sub-Saharan Africa with the highest burden of zero fruits/vegetables consumption. This study aims to access factors associated with zero fruits/vegetables consumption among children aged 6-23 months in Ethiopia. METHODS The study analyzed Ethiopian Mini Demographic and Health Survey 2019 dataset with a total weighted sample of 1459 young children aged between 6-23 months and who were living with their mothers. Data cleaning, coding and labeling were done using STATA version 14 software. Multilevel mixed effect logistic regression model was employed to identify associated factors. RESULTS Exactly 69.3% of children aged 6-23 months in Ethiopia had zero fruits/vegetables consumption. In the multivariable multilevel binary logistic regression analysis a child from household with middle (AOR = 0.55, 95% CI: 0.35, 0.86) and rich (AOR = 0.37, 95% CI: 0.23, 0.60) wealth index, mothers who aged between 25-34 years old (AOR = 0.44; 95%CI = 0.29-0.69), mothers who were married/living with partner (AOR = 3.21; 95%CI: 1.58-6.52), children of mothers who follow Islamic religion (AOR = 0.34, 95% CI: 0.19, 0.61), mothers who had more than four ANC visits during their most recent pregnancy (AOR = 0.57; 95%CI: 0.39-0.83), children in age group of 12-18 month(AOR = 0.41, 95% CI: 0.28, 0.59), and 19-23 months (AOR = 0.26, 95% CI: 0.17, 0.40), health facility delivery (AOR = 1.52, 95% CI; 1.00-2.30), and small peripheral regions (AOR = 4.40, 95% CI; 1.39-13.97) were found to be significant factors associated with children's zero fruits /vegetables consumption. The Interclass correlation coefficient (ICC) value in the null model was 0.34, which indicates that 34% of the variation in children's zero fruits /vegetables consumption was attributed to the variation between clusters. CONCLUSION This study found that zero fruits/vegetables consumption among children aged 6-23 months in Ethiopia is high. Therefore, efforts should be made by stakeholders who are concerned about optimal diet and health of children to improve fruits/vegetables consumption of children particularly those from poor households, young mothers (15-24), and peripheral regions of Ethiopia. This could be done during ANC follow up visits and during nutrition counseling.

Abstract
BACKGROUND The 2002 World Health Report documented that low fruit and vegetable intake are among the top ten risk factors contributing to attributable mortality and up to three million lives could be saved each year by adequate consumption of F&V across the globe, leading an examination of behavioral preferences of the individual and family social, environmental, and behavioral factors that constitute perceived barriers to fruit and vegetable consumption. OBJECTIVE The study examines factors affecting the choice of eating fruits and vegetables by household members and calculates eating frequency probabilities of different population-origin associated with personal attributes and behavior. METHOD Turkish Health Survey (THS) 2019 data from the Turkish Statistical Institute (TSI) national representative household panel is applied. Estimating a random-effect bivariate probit model of fruit and vegetable choice, we calculated marginal probabilities of choosing fruits and vegetables, the joint probability of choosing both, and conditional probabilities between choosing to eat either, detecting consumption synergy. RESULTS The role of uncontrolled variables in choosing to eat fruits and vegetable (F&V) differs between the decision of an average family and the decision of individual family members. The attitude is positive for an average family and contrasts with the negative attitude among some family members. Most individual and family attributes inversely affect fruit and vegetable choice across different groups, while a positive relationship exists between the likelihood of fruit and vegetable choice and attributes such as age, marital status, education, weight, having health insurance, income, and time and forms of physical activity. CONCLUSION AND RECOMMENDATION Instead of a general policy for the implementation of a healthy and balanced nutrition program to improve fruit and vegetable eating frequency, it appears more effective to adopt programs with distinct characteristics that segregate society into different cohorts. We suggest appropriate policies and offer suitable approaches to reach targeted groups.

Abstract
Objective: To gather research evidence on the association between diet and depression and anxiety among college students. Methods: Systematic searches were performed in CINAHL, PsycINFO, PubMed, and ScienceDirect databases to identify potentially relevant articles published between January 2000 and September 2020. Data were extracted from 21 selected studies. Results: Most of the cross-sectional studies found a positive association between diet and depression and anxiety; however, a few studies found inconsistent results. Moreover, several interventional studies demonstrated that a healthy diet (including consumption of fruit and vegetables) improved depression in the intervention group. Conclusions: The methodological limitations of cross-sectional studies to explain causality and the limited number of prospective interventional studies point to a pressing need to conduct more prospective, longitudinal, and randomized controlled trials to generalize the causal associations between diet and depression and anxiety. Further research is needed to investigate the biological mechanisms of nutrients' actions on anxiety and depression.

Abstract
Aim; This study was planned and conducted to examine the change in food consumption and nutritional supplement use during the COVID-19 pandemic according to individuals' status of anxiety and Mediterranean diet adherence. Methods; This prospective, cross-sectional research was completed online with the participation of 949 people (66.4% women). The Mediterranean Diet Adherence Screener Scale (MEDAS) and Coronavirus Anxiety Scale (CAS) were applied. After this section of the questionnaire was completed, the participants were tasked with answering questions regarding changes in food consumption and use of nutritional supplements during the pandemic. Results; While 50.8% of the participants had low adherence to the Mediterranean diet, 18.2% were considered to have a high adherence. It was observed that legume (p = 0.001), milk and dairy (p = 0.01), and fruit (p < 0.001) consumption of participants with high adherence to the Mediterranean diet increased during the pandemic, and packaged food (p < 0.001) consumption decreased. The increase in the consumption of fruit (p < 0.001) and vegetables (p = 0.018) were significantly higher in the group with anxiety. Age, sex, educational status, positive COVID-19 test, place of residence, CAS score and MEDAS score affect the use of dietary supplements according to binary logistic regression (R2 = 0.106 p < 0.001). The three most commonly used supplements were identified as vitamins C, D and B12. Conclusions: These results can shed light on how to prepare for possible future pandemics when it comes to dealing with anxiety through diet.

Abstract
Human flourishing, the state of optimal functioning and well-being across all aspects of an individual's life, has been a topic of philosophical and theological discussion for centuries. In the mid-20th century, social psychologists and health scientists began exploring the concept of flourishing in the context of health and high-level wellness. However, it is only in recent years, in part due to the USD 43 million Global Flourishing Study including 22 countries, that flourishing has entered the mainstream discourse. Here, we explore this history and the rapid acceleration of research into human flourishing, defined as "the relative attainment of a state in which all aspects of a person's life are good" by the Harvard University's Flourishing Program. We also explore the construct of "vitality", which refers to a sense of aliveness, energy, and motivation; we contend that this has been neglected in the flourishing movement. We explore why incorporating measures of vitality, together with a broader biopsychosocial approach, considers all dimensions of the environment across time (the total exposome), which will greatly advance research, policies, and actions to achieve human flourishing.

Protective role of antioxidant supplementation for depression and anxiety: A meta-analysis of randomized clinical trials. J Affect Disord 2023; 323:264-279. [PMID: 36442656 DOI: 10.1016/j.jad.2022.11.072] [Citation(s) in RCA: 15] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/02/2022] [Revised: 11/05/2022] [Accepted: 11/20/2022] [Indexed: 11/27/2022]
Abstract
BACKGROUND New research supports an integrated approach to treating depression, and lifestyle modifications should be a regular component of both preventative and treatment programs. Therefore, in order to investigate the relationship between various antioxidant supplements and depressive status, we carried out a meta-analysis of randomized controlled trials (RCT). METHODS We thoroughly searched PubMed, Medline, Scopus, and Web of Science databases to screen publications focusing on the effects of antioxidant supplements on depression status. The meta-analysis mainly compared depression scores between groups that received antioxidant supplements and controls. We also pooled studies reporting changes in anxiety status as a secondary outcome. RESULTS 52 studies with 4049 participants were eventually identified. The meta-analysis found that the positive effect of antioxidant supplementation, such as magnesium (SMD = 0.16, p = 0.03), zinc (SMD = 0.59, p = 0.01), selenium (SMD = 0.33, p = 0.009), CoQ10 (SMD = 0.97, p = 0.05), tea and coffee (SMD = 1.15, p = 0.001) and crocin (MD = 6.04, p < 0.00001), on depressive status were all significant. And antioxidant supplementation also showed significant improvement in anxiety (SMD = 0.40, p < 0.00001). Subgroup analysis by scale types and countries were performed, and antioxidant supplementation's positive effects on depressive and anxiety states remained significant. LIMITATIONS This study did not limit the characteristics of the included population, and the diversity of scales also contributed to the heterogeneity. CONCLUSION Intake of antioxidant supplements is associated with improved depression and anxiety states, further affirms the therapeutic potential of antioxidant supplements as adjunctive therapy to conventional antidepressants.

[PMID: 36771431 PMCID: PMC9920499 DOI: 10.3390/nu15030725] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Revised: 01/25/2023] [Accepted: 01/27/2023] [Indexed: 02/04/2023] Open
Abstract
Due to the lack of studies comparing the determinants of well-being in omnivores and vegetarians, we examined associations of socio-demographic and lifestyle factors, including adherence to a Mediterranean-style diet, in relation to well-being in omnivorous, vegetarian, and vegan women. Well-being was assessed using a validated WHO-5 Well-Being Index. Adherence to the Mediterranean-style diet was determined using a modified Mediterranean diet score. The study was conducted on 636 women (23.9 ± 5.7 years), of whom 47.3% were omnivores, 33.2% vegetarians, and 19.5% vegans. The good well-being group (WHO-5 Index ≥ 13 points) comprised 30.9% of the omnivores, 46.0% of the vegetarians, and 57.3% of the vegans. The remaining participants were classified as belonging to the poor well-being group (<13 points). Compared to the omnivores, the vegetarians and vegans had a 1.6-fold (95% CI: 1.04-2.42) and a 2.4-fold (95% CI: 1.45-3.99) higher probability of having good well-being, respectively. In omnivores, the predictors of good well-being were adherence to the Mediterranean-style diet (a 1-score increment was associated with a 17% higher probability of good well-being, P-trend = 0.016), higher self-perceived health status, and lower levels of stress. In vegetarians and vegans, it was older age, higher physical activity (≥3 h/week), 7-8 h sleep time, and similarly to omnivores' higher self-perceived health status and lower stress level. Our findings indicate that following a Mediterranean-style diet was associated with better well-being in omnivores. Furthermore, we identified that different determinants were associated with well-being in omnivorous and vegetarian and vegan women.

Associations of overall and specific carbohydrate intake with anxiety status evolution in the prospective NutriNet-Santé population-based cohort. Sci Rep 2022; 12:21647. [PMID: 36517506 PMCID: PMC9750050 DOI: 10.1038/s41598-022-25337-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Accepted: 11/29/2022] [Indexed: 12/15/2022] Open
Abstract
We investigated the association between carbohydrate intake and anxiety evolution within the general-population NutriNet-Santé cohort (N = 15,602; 73.8% female; mean age = 53.8y; mean follow-up = 5.4y). Carbohydrate intake was estimated at baseline from ≥ 2 24-h dietary records. Trait anxiety (STAI-T) was measured once at baseline (2013-2016) and once at follow-up (2020), resulting in 4 groups: "None" = absence of high anxiety (STAI-T > 40 points) at any time point; "Transient" = high anxiety only at baseline; "Onset at follow-up" = high anxiety only at follow-up; "Persistent" = high anxiety at baseline and follow-up. Polytomous logistic regression models revealed that sweetened beverage intake was associated with higher odds of "Transient" anxiety (ORQ4vsQ1 = 1.11; 95% CI 1.02-1.21). Intake of complex carbohydrates (ORQ4vsQ1 = 1.12; 1.01-1.25) was associated with higher odds of anxiety "Onset at follow-up." The % energy from carbohydrates (ORQ4vsQ1 = 1.11; 1.03-1.19), intakes of total carbohydrates (ORQ4vsQ1 = 1.10; 1.03-1.18) and complex carbohydrates (ORQ4vsQ1 = 1.09; 1.02-1.17) were associated with higher odds of "Persistent" anxiety, whereas 100% fruit juice intake showed lower odds of "Persistent" anxiety (ORQ4vsQ1 = 0.87; 0.81-0.94). This prospective study found significant associations between dietary carbohydrate intake and anxiety status evolution among French adults. The findings could help inform dietary interventions aimed at anxiety prevention and management.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:13189. [PMID: 36293768 PMCID: PMC9603697 DOI: 10.3390/ijerph192013189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Revised: 10/02/2022] [Accepted: 10/11/2022] [Indexed: 06/16/2023]
Abstract
(1) Background: The psychological status of employees, especially vulnerable populations, has received considerable research attention. However, as a newly emerging and popular occupation in the gig industry, food delivery drivers have received little attention. The majority of these workers are immigrants who are already in a precarious position due to a lack of available jobs, inadequate medical care, poor diets, and communication and acculturation difficulties even before they take these jobs, which involve long working hours and exposure to the elements. (2) Methods: To examine the anxiety and depression symptoms of these workers and possible influencing factors, a cross-sectional study was conducted with a sample of food delivery drivers working for the Meituan Company (one of the largest e-platform companies in China). Anxiety and depression scales were adapted from the GAD-7, and the PHQ-9 was used to assess participants' related symptoms. Differences were compared in terms of sociodemographic, work situation, and lifestyle variables. Binary logistic regressions were conducted to analyze the effects of various factors on the two psychological dimensions. (3) Results: Among the 657 participants, the proportions of participants reporting anxiety and depression symptoms were 46.0% and 18.4%, respectively. Lack of communication with leaders (ORAN = 2.620, 95% CI: 1.528-4.493, p < 0.001; ORDE = 1.928, 95% CI: 1.039-3.577, p = 0.037) and poor sleep quality (ORAN = 2.152, 95% CI: 1.587-2.917, p < 0.001; ORDE = 2.420, 95% CI: 1.672-3.504, p < 0.001) were significant risk factors for both anxiety and depression symptoms. Women (OR = 2.679, 95% CI: 1.621-4.427, p < 0.001), those who climbed ≥31 floors per day (OR = 2.415, 95% CI: 1.189-4.905, p = 0.015), and those with a high frequency of breakfast consumption (OR = 3.821, 95% CI: 1.284-11.369, p = 0.016) were more likely to have anxiety symptoms. Participants who earned less than 5000 RMB (OR = 0.438, 95% CI: 0.204-0.940, p = 0.034), were unwilling to seek medical help (OR = 3.549, 95% CI: 1.846-6.821, p < 0.001), or had a high frequency of smoking (OR = 5.107, 95% CI: 1.187-21.981, p = 0.029) were more likely to be depressive. (4) Conclusion: The existence of communication channels with leaders and good sleep quality are protective factors for anxiety and depression symptoms. Participants who were female, climbed ≥31floors per day, and had a high frequency of eating breakfast were more likely to have anxiety symptoms, while earning less, unwillingness to seek medical help, and a high frequency of smoking were risk factors for depression symptoms.

Abstract
Background: Nutritional beliefs play an important role when it comes to food choice. However, little attention has been paid to which foods individuals believe to be comforting when experiencing stress. With increasing health awareness in the general public, this study aims to examine whether the nutritional belief exists that only healthy foods relieve stress. If so, we are interested in its relationship to Orthorexia Nervosa (ON) tendencies. Methods: 175 participants (mean age 28.5 ± 7.8 years, 124 females) completed questionnaires to assess beliefs about stress-relieving foods and ON tendencies. Principal component analysis was used to reduce foods to food groups. Subsequently, a latent profile analysis was performed to identify groups with distinct nutritional beliefs. Results: Among eight distinct groups, one group (8% of the sample) reported the belief that exclusively healthy foods relieve stress. Multinominal logistic regressions showed that higher ON tendencies were associated with that group. Conclusions: Our findings suggest that individuals with stronger ON tendencies believe that, in particular, healthy foods relieve stress. This indicates that nutritional beliefs in ON concern not only the somatic consequences of certain foods, but also psychological consequences, which might also drive orthorexic behaviour. This offers a new target for the diagnosis and treatment of ON.

Abstract
Polycystic ovary syndrome (PCOS) is an endocrine disorder evolving as a global threat to women's health. However, its multifactorial etiology causes difficulty in eliminating it. The interrelation between the gut microbiota and metabolic disorders has been trending recently, giving rise to new opportunities on the etiology and pathogenesis of PCOS. Lifestyle interventions such as healthy diet, physical exercises, and behavioral interventions such as regulation of stress and sleep cycles have been identified to improve the symptoms of PCOS across the endocrinological, metabolic and psychological scales and are recommended as the first line of treatment for PCOS. The impact of the unhealthy lifestyle factors on intestinal dysbiosis that cause PCOS is summarized in this review. This review also provides an insight on the therapeutic approaches that primarily target the gut microbiota and offers novel gut microflora-associated treatment strategies for PCOS. Further, this survey also highlights the need for the implementation of lifestyle management strategies and strongly recommends a healthy and stress-free lifestyle to promote gut health and manage PCOS.

Abstract
Objective: To establish the prevalence of mood and wellness behaviors in college students across a school year. Methods: 1,554 college students (69.4% female; average age 18.8 years) were followed with daily surveys on wellness behaviors for the school year. 1,207 participants completed at least 50% of daily surveys on mood, exercise, sleep, nutrition, mindfulness practice and singing/playing musical instrument. Results: Over 88.7% of college students reported at least one wellness behavior each day with 17.7% reporting 4 or more. Each of the wellness behaviors, however, displayed distinct prevalence patterns, varied significantly across the school year, and often across a given school week. Almost every individual wellness behavior was associated with a positive mood, and the cumulative number of daily wellness behaviors was a strongly associated with mood state. Conclusions: Daily wellness behaviors are collectively common, vary significantly within individuals, and are strongly associated with positive mood, both individual and cumulatively.

Abstract
Background: The coronavirus disease 2019 (COVID-19) pandemic altered lifestyles and impacted mental health of many adults. Engaging in physical activity, avoiding prolonged sitting, and consuming a healthy diet improve mental health. The current study investigated the association between health-related lifestyle behaviors on feelings of anxiety and depression in adults during the early stages of the COVID-19 pandemic. Methods: Adults (n=796) living in the United States completed an internet-based survey in Spring 2020 that included validated survey instruments for moods, physical activity, sitting and dietary behaviors. Multivariate multiple regression models were used to assess the association between health-related lifestyle behaviors and feelings of anxiety and depression. Results: A majority (70.7%; 95% CI: [0.607, 0.807]) of participants met physical activity (PA) guidelines, 43.7% (95% CI: [0.287, 0.587]) sat for ≥ 8 hours per day, and 87.7% (95% CI [0.807, 0.947]) ate a healthy diet. Our final models explained 6.2% and 9.8% of the variance in anxiety and depression, respectively. Vigorous PA (anxiety: B=-0.111, 95% CI: [-0.171,0.000]; depression: B=-0.111, 95% CI: [-0.186,-0.037]) and dietary behaviors (anxiety: B=-0.112, 95% CI: [-0.180,-0.444]; depression: B=-0.112, 95% CI: [-0.213,-0.076]) were associated with reduced feelings of anxiety and depression while sitting time (anxiety: B=0.119, 95% CI: [0.000,0.199]; depression: B=0.119, 95% CI: [0.199,0.199]) were associated with greater feelings of anxiety and depression. Conclusion: Engaging in vigorous physically activity, reducing sitting time, and consuming a healthy diet was associated with reduced feelings of anxiety and depression during the early part of the pandemic. The aforementioned modifiable lifestyle behaviors are independent of each other suggesting improvements in one behavior may improve feelings of anxiety and depression.

Abstract
Zero vegetable or fruit and egg and/or flesh foods are the latest indicators for assessing infant and young child feeding practices. Understanding national and subnational heterogeneity and regional clustering in children with SSA is becoming increasingly essential for geographic targeting and policy prioritization. Geographical case identification, determinants, and impacts were all investigated. SSA children's consumption of vegetable or fruit, egg and/or flesh food, and both were low. In SSA, some portions of the Southern, South direction of the Western and Central regions have a lower weight of all bad conditions than others, although children continue to suffer in considerable numbers in all disadvantage circumstances. Children under the age of 1 year, from rural areas, uneducated families, and low income were all disadvantaged by both feeding techniques. To improve child nutrition status, multisectoral collaboration is essential. This framework allows for the tracking, planning, and implementation of nutritional treatments.

This study aimed to investigate the changes in the purchase and consumption of fruit and vegetables in Sri Lanka during the COVID-19 pandemic. Methods An online cross-sectional survey assessed the self-reported changes in fruit and vegetable consumption and purchase using Google forms. Logistic regression analyses were performed to assess the association between decreased consumption of imported fruits and increased home-grown food intake with socio-demographic variables. Results Among the 3621 survey respondents, 63.0% and 43.3% reported a decreased intake of imported and local fruits purchased from the market, respectively. Although the overall vegetable consumption has declined, the leafy vegetable consumption has increased by 40.7%. Imported fruit intake has significantly reduced among youngsters, males, respondents living in municipal areas, employed, and those with lower monthly incomes. Among the respondent, 48.9% declared an increased consumption of home-grown fruits or vegetables. Responders living away from Colombo and rural areas were more likely to report a higher intake of home-grown fruits and vegetables (OR 2.021; 95% CI, 1.762-2.318, P < 0.001). Employed males residing in municipal areas were less likely to report an increased intake (OR 0.689; 95% CI, 0.574-0.827, P < 0.001). Conclusion Purchase of imported and local fruits from the market has reduced. Although the overall vegetable consumption was decreased, there has been an increase in the consumption of leafy vegetables. Furthermore, consumption of home-grown fruits and vegetables has increased considerably. Well-established food distribution programs are essential in future pandemics to promote healthy eating.

Investigation of the Associations between Diet Quality and Health-Related Quality of Life in a Sample of Swedish Adolescents. Nutrients 2022; 14:nu14122489. [PMID: 35745218 PMCID: PMC9231196 DOI: 10.3390/nu14122489] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 06/13/2022] [Accepted: 06/14/2022] [Indexed: 02/01/2023] Open
Abstract
Most adolescents do not consume a high-quality diet, while self-reported mental health problems within this group are increasing. This study aimed to investigate the association between diet quality and health-related quality of life, and to explore the differences in diet quality and health-related quality of life between gender and parental education status. In this cross-sectional study, a detailed web-based recall method was implemented to determine dietary intake, which was analysed using the newly developed Swedish Healthy Eating Index for Adolescents 2015 (SHEIA15) and the Riksmaten Adolescents Diet Diversity Score (RADDS), to determine diet quality. The KIDSCREEN-10 questionnaire was used to measure health-related quality of life, and parental education was self-reported through questionnaires. Parental education was divided into two groups: ≤12 years or >12 years. The study included 1139 adolescents from grade 7 (13−14 years old), 51% were girls. The results showed that girls had higher scores for healthy eating and diet diversity but lower scores for health-related quality of life. A positive association was found between diet diversity and health-related quality of life (Adj R2 = 0.072, p = 0.001), between vegetable/fruit consumption and health-related quality of life (Adj R2 = 0.071, p = 0.002), and between healthy eating and diet diversity (Adj R2 = 0.214, p < 0.001). No association was found between healthy eating and health-related quality of life for all participants. The mean scores for healthy eating and diet diversity were significantly higher in the higher education parental group. In conclusion, higher diet diversity and increased fruit and vegetable consumption could be a strategy to improve health-related quality of life among adolescents. There is a need to promote better diet quality, especially in households of low parental education. In addition, there is a further need to investigate the potential benefits of improved diet quality on mental health and overall well-being.

Tuck NJ, Farrow CV, Thomas JM. Frequency of fruit consumption and savoury snacking predict psychological health; selective mediation via cognitive failures. Br J Nutr 2022; 129:1-26.

Abstract
While there is growing interest in the link between diet and psychological health, there is a surprising lack of studies investigating the precise associations between nutrient-rich foods (such as fruit and vegetables) versus nutrient-poor foods (such as energy-dense savoury and sweet snacks), and psychological health. Similarly, the psychological processes underpinning the relationship between dietary intake and psychological health remain unclear. Hence, the present study aimed to explore the relationship between dietary consumption and psychological health, with cognitive processes as a theoretical mediator. This cross-sectional online study included 428 healthy adults (53% female; mean age= 39.7, SD= 13.0), with participants completing a range of validated questionnaires measuring dietary habits and psychological health. Stepwise multiple regression revealed that more frequent consumption of fruit was associated with reduced symptoms of depression (β = -.109, p = 0.025) and greater positive psychological wellbeing (β = .187, p < 0.001). Conversely, more frequent savoury snacking was associated with increased anxiety (β = .127, p = 0.005). Further, mediation analyses revealed that more frequent consumption of savoury snacks was associated with increased symptoms of depression, stress, anxiety, and reduced psychological wellbeing, via an increase in cognitive failures (ps < 0.001). These results provide new insights on the independent associations between certain types of food and psychological health, and the psychological mechanisms that may mediate these. Further work is now required to establish causality and determine whether these may represent modifiable dietary targets that can directly (and indirectly) influence our psychological health.

[PMID: 35628067 PMCID: PMC9141935 DOI: 10.3390/healthcare10050930] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2022] [Revised: 05/15/2022] [Accepted: 05/16/2022] [Indexed: 01/25/2023] Open
Abstract
A direct association between health-related quality of life (HQoL) and nutrition remains unclear, although lifestyle habits are known to impact on human health. Thus, the aim of this study was to estimate an association between dietary habits, such as vegetable and fruit consumption, in particular, and HQoL. SF-36 (RAND-SF-36) and the Dietary Habits and Nutrition Beliefs Questionnaire (KomPAN) were addressed to Polish pharmacists with a valid professional license. After the preliminary verification, 667 pharmacists were included into the study, and altogether, 11 questions from the KomPAN questionnaire and all RAND-SF-36 multiple choice questions were processed for statistical analysis. All HQoL scores, excluding physical functioning and role-physical, were significantly higher in the group declaring fruit consumption ≥1 time per day (p < 0.005), while physical functioning (p = 0.008) and general health (p = 0.03) were significantly higher in the group declaring vegetable consumption ≥1 time per day. Thus, there is indeed a positive association between vegetable and fruit consumption and HQoL. Increased fruit intake could certainly impact on the health-related quality of life of Polish pharmacists, primarily in terms of mental functioning, while increased vegetable intake could impact in terms of physical functioning.

Role of diet and its effects on the gut microbiome in the pathophysiology of mental disorders. Transl Psychiatry 2022; 12:164. [PMID: 35443740 PMCID: PMC9021202 DOI: 10.1038/s41398-022-01922-0] [Citation(s) in RCA: 53] [Impact Index Per Article: 26.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2021] [Revised: 03/22/2022] [Accepted: 03/29/2022] [Indexed: 12/12/2022] Open
Abstract
There is emerging evidence that diet has a major modulatory influence on brain-gut-microbiome (BGM) interactions with important implications for brain health, and for several brain disorders. The BGM system is made up of neuroendocrine, neural, and immune communication channels which establish a network of bidirectional interactions between the brain, the gut and its microbiome. Diet not only plays a crucial role in shaping the gut microbiome, but it can modulate structure and function of the brain through these communication channels. In this review, we summarize the evidence available from preclinical and clinical studies on the influence of dietary habits and interventions on a selected group of psychiatric and neurologic disorders including depression, cognitive decline, Parkinson's disease, autism spectrum disorder and epilepsy. We will particularly address the role of diet-induced microbiome changes which have been implicated in these effects, and some of which are shared between different brain disorders. While the majority of these findings have been demonstrated in preclinical and in cross-sectional, epidemiological studies, to date there is insufficient evidence from mechanistic human studies to make conclusions about causality between a specific diet and microbially mediated brain function. Many of the dietary benefits on microbiome and brain health have been attributed to anti-inflammatory effects mediated by the microbial metabolites of dietary fiber and polyphenols. The new attention given to dietary factors in brain disorders has the potential to improve treatment outcomes with currently available pharmacological and non-pharmacological therapies.

Abstract
Background: Few studies have examined the associations of pediatric weight management interventions (PWMIs) with reduction in parental stress. We sought to examine the extent to which a PWMI reduces parental stress and whether changes in parental healthful feeding practices and support for physical activity are associated with reduction in parental stress. Methods: We analyzed data from the Clinic and Community Approaches to Healthy Weight randomized controlled trial (RCT). Parental stress change over 12 months was analyzed using a multivariate mixed linear model. We then examined associations of changes in healthful feeding practices and support for physical activity over 12 months with changes in stress using a multivariate linear model. Results: In multivariate-adjusted models, participation in a PWMI was associated with decrease in parental stress at 12 months, with a mean difference (MD) of -0.24 U [95% confidence interval (CI): -0.45, -0.04]. Increases in scores for exercising regularly [MD = -0.27 (95% CI: -0.52, -0.03)] and keeping healthy food at home [MD = -0.38 (95% CI: -0.66, -0.10)] were associated with decrease in stress. Conclusions: Participation in a PWMI was associated with decrease in parental stress. Encouraging parents of children with overweight and obesity to keep healthy food in the house and exercise regularly may represent important strategies to improve parental stress. PWMI effectiveness studies should consider parental stress as an outcome while addressing social determinants of health that may influence parental stress.

Abstract
“Blue Zones” are geographical regions where people live to be non-agenarians and centenarians with significantly better rates of mental wellness when compared to the average American. It was discovered that these areas have nine unique evidenced-based lifestyle principles, with one of their main principles being the consumption of a plant-based diet. With this in mind, we performed a worksite intervention with the objective of understanding the relationships among Blue Zones knowledge, a plant-based lifestyle, and improvements in overall mental wellness during the COVID-19 pandemic. During spring 2021, we recruited 52 employees from a public, mid-sized university in the southwestern United States to participate in an 8-week virtual intervention that included weekly topic presentations, cooking demonstrations, and Blue Zones education. Participants were also assigned to weekly wellness counseling groups integrating Motivational Interviewing based principles that included additional, relevant conversation topics and support. The final sample (n = 52 participants) had a mean age of 45.6 ± 10.6 years. Participants were predominantly women (84.6%) and nearly half were married (44.2%). The majority attended graduate school (59.6%) and identified as White (84.6%). Paired-samples t-tests indicated significant improvements in all mental wellness outcomes and Healthy Eating Index-2015 (HEI-2015) scores over time (p's < 0.001 to 0.02). Multiple linear regression models revealed that Blue Zones knowledge (β = −0.037, p = 0.010) significantly negatively predicted Patient Health Questionnaire-9 (PHQ-9) scores at 8-weeks. Additionally, multiple linear regression models indicated small group attendance (β = −1.51, p = 0.003) and Blue Zones knowledge (β = −0.81, p = 0.012) significantly negatively predicted sleep scores at 8-weeks. When HEI-2015 total scores were also included at baseline and 8-weeks (post-intervention), Blue Zones knowledge (β = −0.031, p = 0.049) was a borderline significant predictor of PHQ-9 at 8-weeks. Additionally, small group sessions (β = −1.52 p = 0.005) were a significant predictor of sleep at 8-weeks. The intervention illustrated that virtual intervention strategies can improve nutrition and mental wellness for future advancement in life quality and wellbeing.

Abstract
Diets rich in fruits and vegetables are associated with better psychological wellbeing and cognitive functions, although it is unclear which molecules and mechanisms are involved. One potential explanation is the inhibition of monoamine oxidases (MAOs), which have been linked to several neurological disorders. The present study investigated the ability of kiwifruit to inhibit MAO-A and MAO-B, refining an in vitro assay to avoid confounding effects. Ultra-performance liquid chromatography/mass spectrometry (UPLC-QTOF) and nuclear magnetic resonance spectroscopy (NMR) were used to select individual kiwifruit metabolites for further analysis. Moreover, extracts of other common fruits and vegetables were screened to identify promising candidate inhibitors. Multiple extracts and compounds inhibited both enzymes, and the selective inhibition of MAO-B by the major kiwifruit specialized metabolite D-(−)-quinic acid was observed. These results suggest that fruits and vegetables contain metabolites that inhibit the activity of MAO-A and -B, offering a potential natural option for the treatment of neurological disorders, in which MAOs are involved.

Abstract
Positive Psychological (PP) constructs (e.g., optimism and gratitude) may impact the adherence to healthy behaviors, including diet, though prior studies have shown mixed findings. This qualitative study explored the relationships between PP constructs and dietary behaviors among 21 adults with metabolic syndrome through semi-structured interviews. Directed content analysis led to five themes: eating healthfully leads to PP constructs, PP constructs lead to eating healthfully, eating healthfully prevents negative emotions, healthy behaviors associated with diet, and an upward healthy spiral. Given the close relationship between PP constructs and diet, these may be targeted to improve diet in risk populations through interventions that promote well-being.

Abstract
Anxiety disorders are the most common group of mental disorders. There is mounting evidence demonstrating the importance of nutrition in the development and progression of mental disorders such as depression; however, less is known about the role of nutrition in anxiety disorders. This scoping review sought to systematically map the existing literature on anxiety disorders and nutrition in order to identify associations between dietary factors and anxiety symptoms or disorder prevalence as well as identify gaps and opportunities for further research. The review followed established methodological approaches for scoping reviews. Due to the large volume of results, an online program (Abstrackr) with artificial intelligence features was used. Studies reporting an association between a dietary constituent and anxiety symptoms or disorders were counted and presented in figures. A total of 55,914 unique results were identified. After a full-text review, 1541 articles met criteria for inclusion. Analysis revealed an association between less anxiety and more fruits and vegetables, omega-3 fatty acids, “healthy” dietary patterns, caloric restriction, breakfast consumption, ketogenic diet, broad-spectrum micronutrient supplementation, zinc, magnesium and selenium, probiotics, and a range of phytochemicals. Analysis revealed an association between higher levels of anxiety and high-fat diet, inadequate tryptophan and dietary protein, high intake of sugar and refined carbohydrates, and “unhealthy” dietary patterns. Results are limited by a large percentage of animal and observational studies. Only 10% of intervention studies involved participants with anxiety disorders, limiting the applicability of the findings. High quality intervention studies involving participants with anxiety disorders are warranted.

Abstract
Background Evidence indicates the lower intake of fruits and vegetables than the recommended daily amount. Study aimed at determining the effects of peer education intervention on the consumption of fruits and vegetable in housewives. Methods A quasi-experimental was conducted with 130 housewives referring to health care centers in Bandar Abbas, Iran. Sixty-five subjects were recruited in each of the intervention and the control groups. Intervention group were divided into three subgroups each receiving a seven-sessions educational programs (lecturing and group discussion) through peers about the importance of benefits of fruits and vegetables consumption. Participants were followed for two months. Data were collected using a questionnaire in two stages of pre- and post-intervention. Differences in the outcome before and after the intervention were tested using T-test and paired T-test. Results The daily servings of fruits and vegetables in the intervention group increased from 1.73 to 4.20 and in the control group from 1.96 to 2.16; a statistically significant difference was also observed between the groups (P < 0.001). After the intervention benefits and self-efficacy of fruits and vegetables consumption significantly increased and perceived barriers of fruits and vegetables consumption significantly decreased in the intervention group (P < 0.001). Conclusion Peer education improves benefits and self-efficacy, reduces barriers, and increases the daily servings of fruits and vegetables in housewives.

[PMID: 34900574 PMCID: PMC8641063 DOI: 10.1016/j.mhp.2021.200223] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 01/30/2021] [Revised: 10/11/2021] [Indexed: 01/09/2023]
Abstract
Consumption of fruits and vegetables is correlated with improved mental wellbeing. Although this growing body of research has been recognized by researchers and clinicians in high-income countries, fewer studies examining this relationship have been conducted in low- and middle-income settings. In this study, we sought to estimate the association between fruit and vegetable intake and symptoms of depression and anxiety. We conducted a cross-sectional study among 242 family caregivers of people with dementia in southwestern Uganda. Fruit and vegetable intake in the past week was measured with a food frequency questionnaire. Depression and anxiety were assessed using the depression and anxiety subscales of the 42-item Depression, Anxiety and Stress Scales. Multivariable regression models were used to estimate the associations between fruits and vegetable consumption and depression and anxiety, adjusting for caregiving burden and other potential confounders. Depression symptom severity was negatively associated with consumption of jackfruits (b =-4.68; 95% confidence interval [CI], -8.96 to -0.39), green leafy vegetables (b =-14.1; 95% CI, -18.0 to -10.1), root vegetables (b =-14.0; 95% CI, -19.5 to -8.63), and other vegetables (b =-14.8; 95% CI, -19.3 to -10.3), and frequent consumption of vegetables (b =-1.91; 95% CI, -3.77 to -0.04). Anxiety symptom severity was negatively associated with consumption of green leafy vegetables (b =-12.2; 95% CI, -16.0 to -8.46), root vegetables (b=-12.6; 95% CI, -17.5 to -7.58), and other vegetables (b =-12.7; 95% CI, -17.0 to -8.40), and frequent consumption of vegetables (b =-2.07; 95% CI, -3.84 to -0.29). Our results suggest that fruit and vegetable consumption is associated with reduced depression and anxiety symptoms.

Consumption of Dietary Guidelines for Americans types and amounts of vegetables increases mean Subjective Happiness Scale scores: A randomized controlled trial. J Acad Nutr Diet 2021; 122:1355-1362. [PMID: 34793989 DOI: 10.1016/j.jand.2021.11.009] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2021] [Revised: 11/09/2021] [Accepted: 11/10/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND The health benefits of diets rich in fruits and vegetables (FV) are well established. Recent observational and intervention research suggests that FV consumption may also exert a positive effect on psychological well-being. OBJECTIVE This study aimed to assess changes in mean Subjective Happiness Scale (SHS) scores in response to consuming DGA recommended types and amounts of vegetables. It was hypothesized that increased vegetable consumption would increase mean SHS scores. DESIGN This study investigated a secondary outcome of a randomized, parallel, non-blinded controlled trial with a 1:1 allocation ratio to a provided vegetable intervention or attention control group. PARTICIPANTS/SETTING Men and women (n=75) aged 18-65 years, body mass index ≥25 kg/m2, with low habitual vegetable consumption were recruited from Grand Forks, ND, December 2016 to January 2018, for this community-based study. INTERVENTION The vegetable intervention consisted of an 8-week feeding phase during which participants were provided with vegetables in DGA recommended types and amounts. The attention control group was not provided vegetables but completed the same testing schedule as the vegetable intervention group. MAIN OUTCOME MEASURE Mean SHS scores were assessed before and after the intervention. STATISTICAL ANALYSES Mean SHS scores were analyzed using a 2-way factorial mixed linear model analysis of variance. RESULTS A significant interaction between treatment and visit (P=0.015) revealed greater mean SHS scores at week 8 than at baseline in the vegetable intervention group (+0.23 ± 0.11 (mean difference ± standard error of the difference) but no change in the attention control group (-0.15 ± 0.11). CONCLUSIONS Greater mean SHS scores were observed after increasing vegetable consumption to meet DGA recommendations, suggesting that adhering to DGA vegetable guidance may help promote psychological well-being.

Abstract
Allostatic load (AL) is an index that measures physiologic stress associated with chronic disease risk. One factor that may influence overall physiologic stress load and AL is energy consumption, but whether this association differs across different seasons is unknown. We tested whether energy consumption interacted with the season to influence AL in 52 mid-life (40-60 years) women from the Life in All Seasons Study. Women completed an online 24-h recall every 10 days and had components of allostatic load measured seasonally. Women were from the greater Grand Forks, ND catchment area and were followed for one year between July 2012 and July 2014. We found a significant (p = 0.01) interaction between season and energy consumption on AL. Further inspection showed that, during the summer and winter seasons, the average allostatic load rose with relatively higher energy consumption. We also observed a linear and positive association between AL and energy intake in summer (β = 0.0013 ± 0.0004; p = 0.001; r2 = 0.14) and winter (β = 0.0011 ± 0.0004; p = 0.007; r2 = 0.10), but not in fall or spring. These results suggest that factors associated with distinct times of the year promote or prevent the effects of higher energy consumption on physiological stress load. Since allostatic load is linked to elevated disease risk, our results provide additional information that may help to explain seasonal differences in disease risk of some women.

Abstract
Migration to a new country generally entails a variety of social and economic adversities, often reflected in food practices. This paper aims to explore the hedonic dimension of well-being in a food context among a diasporic Syrian community in Stuttgart, Germany. A conceptual framework that integrates the three aspects of well-being (hedonic, psychological and social) with goals for food consumption (functional, symbolic and hedonic) was developed as a guide for the exploration. The research design used semi-structured interviews with 34 Syrian refugees and content-based analysis to obtain a detailed and profound understanding of the relational links between food and well-being. Findings reveal the affective and cognitive components of hedonic well-being and the overall perception of a good food-related life concerning food purchasing, preparation, eating and post-eating. Satisfaction in food-related life was found to be associated with food availability and accessibility, physical health and body functioning, positive emotions, sensory experience, social relationships and overall life satisfaction. The insights gained from this research help to elucidate the concept of food-related well-being in the case of conflict and displacement and to find strategies to promote the well-being of refugees.

Abstract
Research to date has convincingly demonstrated that nutrition impacts depression. Population-based studies have shown that diet, food types, dietary supplements, gut bacteria, endocrine systems and obesity all play a role in depression. While nutrition could provide an important therapeutic opportunity in depression, clinical trials have not shown clinically meaningful results, and it appears unlikely that nutrition is a central determinant of depression. Conversely, however, prior research is inconclusive to inferring that nutrition does not have a clinically significant effect. This would require elucidating precisely when nutrition affects depression which necessitates an alternative, more granular, model for the nutrition–depression interaction. The network theory of mental disorders, which studies how mental disorders arise from a causally related network of symptoms and external factors, is proposed as an alternative model for understanding the complexity of the nutrition–depression link. This approach would uncover which relationships, between aspects of nutrition and depression symptoms, warrant further study at a population and laboratory level. Furthermore, from within nutrition science, is a movement dubbed ‘New Nutrition Science’ (NNS) that aims to integrate biological, social and environmental determinants of nutrition. NNS is important to nutrition–depression research which has yet to reveal how social factors impact the nutrition–depression interaction. Network theory methodology is fully compatible with the network modelling already used in NNS. Embracing both network theory and NNS in future research will develop a full and complex understanding of nutrition in depression.
