“…In South Korea and Japan, rice is deeply associated with cultural identity, memories of family, and the community [ 23 ]. Healthy homemade meals are mostly perceived to be rice-based meals, which tend to be more balanced, higher in nutrients, and lower in calories than Western foods; several studies have been published on the association of rice-centered Japanese diet with the quality of life, sleep, impulsivity, depressive symptoms, and biochemical changes [ 24 , 25 ].…”

Background During the COVID-19 pandemic, urban inhabitants faced significant challenges in maintaining connections with nature, adhering to nutritional guidelines, and managing mental well-being. Objective Recognizing the urgent need for innovative approaches, this study was designed to explore the potential benefits of a specific digital intervention, the rice-farming simulation game Sakuna: Of Rice and Ruin, for nature relatedness, nutritional behaviors, and psychological well-being. Methods A total of 66 adults without any prior major psychiatric disorders residing in an urban area were recruited for the study. They were randomly assigned to 2 groups through block randomization: the immediate intervention group (IIG; 34/66, 52%) and the waitlist group (32/66, 48%). Participants in the IIG were instructed to play the game for at least 4 days per week for 3 weeks, with each session lasting from 30 minutes to 3 hours. Assessments were performed at baseline, week 1, and week 3. The Nature Relatedness Scale (NR) and Nutrition Quotient Scale were used to evaluate nature relatedness and nutritional state, respectively. Furthermore, psychological state was assessed using the World Health Organization Quality of Life–Brief Version (WHOQOL-BREF), Brief Fear of Negative Evaluation Scale, Social Avoidance and Distress Scale, Toronto Alexithymia Scale, State-Trait Anxiety Inventory, Center for Epidemiologic Studies Depression Scale Revised, and Korean Resilience Quotient. Results This study’s results revealed significant time interactions between the IIG and waitlist group for both the total NR score (P=.001) and the score of the self subdomain of NR (P<.001), indicating an impact of the game on nature relatedness. No group×time interactions were found for the total Nutrition Quotient Scale and subdomain scores, although both groups showed increases from baseline. For psychological state, a significant group×time interaction was observed in the total WHOQOL-BREF score (P=.049), suggesting an impact of the game on quality of life. The psychological (P=.01), social (P=.003), and environmental (P=.04) subdomains of the WHOQOL-BREF showed only a significant time effect. Other psychological scales did not display any significant changes (all P>.05). Conclusions Our findings suggest that the rice-farming game intervention might have positive effects on nature relatedness, nature-friendly dietary behaviors, quality of life, anxiety, depression, interpersonal relationships, and resilience among urban adults during the COVID-19 pandemic. The impact of pronature games in confined urban environments provides valuable evidence of how digital technologies can be used to enhance urban residents’ affinity for nature and psychological well-being. This understanding can be extended in the future to other digital platforms, such as metaverses.

Repeated-measures ANOVA was specifically used to compare 2 groups of repeated observations captured at baseline, after 1 week of gameplay, and after 3 weeks of gameplay in the IIG and at the corresponding time points in the WLG.…”

“…[6][7][8][9] Two large studies concluded a positive impact of fruits and vegetables on sleep quality among older adults 10 and university students. 11 Smaller studies found positive associations between sleep quality and other types of food such as milk, 8,12 cherries 8,9 and rice 13 in older adults. Other studies reported a positive impact of nutrients like protein 14,15 or even dietary patterns such as the Mediterranean diet 16,17 in middle aged and older participants.…”

Background: Numerous studies have emphasized the significance of nutrition on the quality of sleep, but little have evaluated the effect of various coexisting dietary markers on middle-aged adults. We assessed the association between sleep quality and a large array of dietary markers among middle-aged, community-dwelling participants.Methods: Data from the first, second and third follow-ups of CoLaus|PsyCoLaus, a populationbased study in Lausanne, Switzerland, was used. Sleep quality was assessed by the Pittsburgh Sleep Quality Index (PSQI). Dietary intake was assessed by a validated food frequency questionnaire.Results: data from 3857 (53% women, 57.2±10.4 years), 2370 (52% women, 60.7±9.5 years) and 1617 (52% women, 63.5±9.0 years) participants from the first, second and third follow-ups was used. Bivariate correlations showed fish, vegetables, fruit, and cheese intake to be associated with a better sleep quality (lower PSQI), while rusks, sugar, and meat intake were associated with a poorer sleep quality (higher PSQI). After multivariable adjustment, participants reporting poor sleep quality (PSQI>5) had a lower Mediterranean diet score and a lower likelihood of complying with the meat and fish recommendations, but the results were inconsistent between surveys. No association was found between sleep quality and macro-or micronutrients in the three surveys. Conclusions:No consistent associations were found between a large panel of nutritional markers and sleep quality. Components of the Mediterranean diet such as dairy, fruits and vegetables might favour good sleep quality, while increased consumption of sugary foods or meat might favour poor sleep quality.
