Rice Diet

Previously, we found that a Japanese diet was associated with psychological status, and a combination of rice and miso was related to mental and physical health. We hypothesized that the intake of a rice-based diet affected mental and physical health and aimed to investigate the consequences of a dietary intervention with rice. We conducted a randomized, open-label, parallel-group clinical trial that included 60 participants, who were randomly assigned to receive either rice-based meals or meals with other cereals for three daily meals over 2 months. The participants were surveyed for psychological status and biochemical changes. Sleep quality index scores showed significant improvement after the rice-based intervention. Additionally, blood oxidative stress levels were reduced in the rice-diet group compared with the no-rice-diet group. Although the molecular mechanisms should be investigated in detail, our findings suggest that controlling oxidative stress through the intake of a rice-centered diet may be key to improving sleep quality.

Sleep quality is important to health, and increasingly viewed as critical in promoting successful, resilient aging. In this review, the interplay between sleep and mental and physical health is considered with a focus on the role of inflammation as a biological pathway that translates the effects of sleep on risk of depression, pain and chronic disease risk in aging. Given that sleep regulates inflammatory biologic mechanisms with effects on mental and physical health outcomes, the potential of interventions that target sleep to reduce inflammation and promote health in aging is also discussed.

AbstractBackgroundAccumulating evidences have shown that lifestyle interventions such as exercise and diet are associated with improved sleep quality. However, the underlying molecular mechanisms remain unclear. Assessing exercise and diet intervention associated changes in circulating metabolomics profile in people with insomnia symptoms may help to identify molecular biomarkers that may link lifestyle changes to improved sleep outcomes.MethodsThe present study is a part of a 6-month randomized lifestyle intervention on sleep disorder subjects. Seventy-two Finnish men (aged: 51.6 ± 10.1 years; body mass index, BMI: 29.3 ± 3.9 kg/m2) with chronic insomnia symptoms who were assigned into different intervention groups completed this study (exercise n = 24, diet n = 27 and control n = 21). The exercise group was assigned to a progressive aerobic exercise training with intensity of 60 – 75% of estimated maximum heart rate, 3 – 5 times a week. The diet group aimed to reduce their total energy intakes by 300 to 500 kcal per day for the first three months. The control group were advised to maintain their current lifestyle. Sleep was assessed by using a non-contact sleep monitoring devise (Beddit sleep tracker). Blood samples were collected in the morning between 7:00 and 9:00 a.m. after overnight fasting. Gas Chromatography Time-Of-Flight Mass Spectrometry (GC-TOF-MS) method was used to determine the serum metabolites.ResultsTwenty-one metabolites were significantly changed in the exercise group, thirty-three metabolites in the diet group and five metabolites in the control group after intervention, respectively. The differential metabolites after exercise intervention were mainly related to glycerolipids and carbohydrates metabolism, while dietary intervention altered mainly amino acids metabolism and fatty acids metabolism related metabolites. We subsequently assessed the change of those metabolites with the change of sleep parameters and found that decreased alpha-ketoisocaproic acid (r = -0.52, p = 0.026) was correlated with improved sleep efficiency (SE) in the exercise group. Change of 3-hydroxybutric acid (r = -0.47, p = 0.025) and D-glucopyranose (r = -0.54, p = 0.006) correlated negatively with SE in the diet group. On the other hand, oxalic acid (r = 0.49, p = 0.021), D-glucopyranose (r = 0.43, p = 0.048), 4-deoxyerythronic acid (r = 0.60, p = 0.004) and tagatose (r = 0.51, p = 0.016) correlated positively with change of SOL, and 2-keto-isovaleric acid (r = 0.45, p = 0.029) correlated with TST in the diet group.ConclusionIn conclusion, this study identified circulating metabolites that may represent a part of a biological mechanism through which lifestyle interventions are associated with improved sleep quality in people with insomnia.

Abstract Objective: To assess the relationship between food insecurity, sleep quality, and days with mental and physical health issues among college students. Design: An online survey was administered. Food insecurity was assessed using the 10-item Adult Food Security Survey Module. Sleep was measured using the 19-item Pittsburgh Sleep Quality Index (PSQI). Mental health and physical health were measured using three items from the Healthy Days Core Module. Multivariate logistic regression was conducted to assess the relationship between food insecurity, sleep quality, and days with poor mental and physical health. Setting: Twenty-two higher education institutions. Participants: College students (n=17,686) enrolled at one of 22 participating universities. Results: Compared to food secure students, those classified as food insecure (43.4%) had higher PSQI scores indicating poorer sleep quality (p<.0001) and reported more days with poor mental (p<.0001) and physical (p<.0001) health as well as days when mental and physical health prevented them from completing daily activities (p<.0001). Food insecure students had higher adjusted odds of having poor sleep quality (adjusted odds ratio [AOR]:1.13, 95% confidence interval [CI]: 1.12-1.14), days with poor physical health (AOR: 1.01, 95% CI: 1.01-1.02), days with poor mental health (AOR: 1.03, 95% CI: 1.02-1.03), and days when poor mental or physical health prevented them from completing daily activities (AOR: 1.03, 95% CI: 1.02-1.04). Conclusions: College students report high food insecurity which is associated with poor mental and physical health and sleep quality. Multi-level policy changes and campus wellness programs are needed to prevent food insecurity and improve student health-related outcomes.

This study aimed to explore the association between sleep quality and its components and both dimensions of health-related quality of life (HRQoL) in a sample of young adults. The sample comprised 337 participants with a mean age of 19.6 y (SD = 2.22). Sleep quality and HRQoL were measured through the Pittsburgh Sleep Quality Index and the SF-12, respectively. Regression analyses were used to investigate the association between sleep quality and HRQoL. Our results confirm the significant association between sleep quality and both physical (p = 0.015; β = −0.138; R2 = 0.07) and mental (p < 0.001; β = −0.348; R2 = 0.22) HRQoL in the adjusted models. However, our results also highlight the differential association between sleep quality and mental and physical HRQoL. Whereas all the sleep quality components (except sleep latency; p = 0.349) were significantly associated with mental HRQoL (p < 0.05), just two subscales (subjective sleep quality; p = 0.021; β = −0.143 and sleep disturbances p = 0.002; β = −0.165) showed a significant association. This study showed that there is a stronger association between sleep quality and mental health than sleep quality and physical health in young adults.

Objective COVID-19 has affected people’s health in various ways. University students are a particularly sensitive group for mental and physical health issues. The aim of this study was to assess and compare the mental and physical health of male and female first-year university students during and before COVID-19. Method Total of 115 first-year university students (54% male) answered questions about mental and physical health. The students were asked to estimate their physical activity, sedentary behavior, loneliness, stress, and sleep quality during COVID-19 opposed to before the pandemic. Result Males had fewer symptoms of anxiety and depression, and their self-esteem was higher than females (p<0.05). Over 50% of both genders estimated their mental health to be worse than before COVID-19. Larger proportion of males (69%) compared to females (38%) estimated that their physical health had worsened than before the pandemic. Larger proportion of females (38%) than males (14%) experience increased loneliness and stress (68% vs. 48%). Over 70% of both genders estimated increased sedentary behavior than before the pandemic, and larger proportion of males (76%), compared to females (56%), estimated that they were less physically active than before COVID-19. About 50% of participants estimated their sleep quality was worse than before COVID-19. Conclusion University students estimated their mental and physical health to have deteriorated during the pandemic. Therefore, it is important that the school and healthcare systems assist students in unwinding these negative health and lifestyle changes that have accompanied the pandemic.
