“…Results from these studies suggest that green tea can be useful for the several health conditions. It has been found that green tea consumption is significantly associated with a lower risk of mortality due to stroke [29] and pneumonia [30] and imparts a lower risk of cognitive impairment [31], depression [32], and psychological distress [33]. These results have been confirmed by other researchers [34][35][36][37].…”

“…Following the suggestion of Kessler et al (2003), we classified women with K6 scores of ≥ 13 as having psychological distress. This cutoff point was used in previous studies that implemented the Japanese version of K6 (Hozawa et al 2009;Watanabe et al 2015). The Japanese version of the K6 demonstrates a screening performance essentially equal to that of the original English version (Furukawa et al 2003(Furukawa et al , 2008.…”

Health benefits of fermented foods are attracting attention worldwide, and they have been traditionally eaten in Japan. Moreover, a recent study showed the association between the higher intake of yogurt and lower prevalence of depressive symptoms during pregnancy. Psychological problems, such as anxiety and depression, during pregnancy are serious health concerns and may increase the risk of adverse outcomes in children. In this study, we explored the association between fermented food consumption and psychological distress in 10,129 pregnant Japanese women, using the fixed data of the Japan Environment and Children's Study (JECS), an ongoing nation-wide birth cohort study. Food consumption was assessed with a semi-quantitative food frequency questionnaire (FFQ), and the Kessler 6-item psychological distress scale (K6) was administered to eligible women during their second or third trimester to eliminate overlap with the period of hyperemesis gravidarum. The mean median gestation in the subjects was 24.8 weeks. In total, 9,030 subjects completed the K6 questionnaire and FFQ. Importantly, the prevalence of the K6 score of ≥ 13 was 3.1% (280 subjects). This value was lower compared to precedent studies, which may reflect that cooperative and health conscious subject participated in the survey. The multivariate logistic regression analysis indicates that the intake of yogurt, lactic acid beverages, cheese, Japanese pickles, miso soup, or fermented soybeans was not significantly associated with a K6 score of ≥ 13. In conclusion,

“…In Japan, the effect of PS or depression on diet has been investigated in relatively small studies (5)(6)(7). In a largescale study of Japanese subjects, the effect of green tea consumption and dietary pattern on depression was investigated (8,9). However, there are few large-scale studies of the association between PS or depression and dietary food and nutrient intake in middle-aged Japanese subjects.…”

SummaryThe aim of this study was to investigate the interaction between psychological stress (PS) and drinking status in relation to diet among middle-aged Japanese men and women in a large-scale cross-sectional study. The study population included 5,587 middleaged Japanese men and 2,718 middle-aged Japanese women who underwent annual health checkups. The subjects were divided into 2 groups (non-drinkers and drinkers) and classifi ed as having low, moderate, or high self-reported PS levels. Energy-adjusted food and nutrient consumption was assessed with a validated food frequency questionnaire. Using a general linear model, food and nutrient consumption was estimated for each self-reported PS level in the 2 groups (non-drinkers and drinkers) and the interactions between self-reported PS levels and drinking status were calculated. In men, pork and beef; squid, octopus, shrimp, and clams; eggs; mushrooms; Japanese-style sweets; ice cream; bread; Chinese noodles; coffee; and soda as foods and protein, animal protein, fat, animal fat, carbohydrate, monounsaturated fatty acid, polyunsaturated fatty acid (PUFA), n-3 PUFA, n-6 PUFA, cholesterol, vitamin D, vitamin B2, vitamin B6, vitamin B12, niacin, pantothenic acid, magnesium, phosphorus, and zinc as nutrients signifi cantly interacted with self-reported PS levels and drinking status (p for interaction Ͻ0.05 for all). No specifi c interactions were found in women. These fi ndings suggest interactions between PS levels and drinking status with consumption of some foods and nutrients, especially macronutrient intake, in men but not in women.
