To the best of our knowledge, changes in mothers' dietary behaviors or perceptions of dietary intake during the COVID-19 pandemic have not been extensively discussed. Therefore, the present study aimed to clarify how the dietary behaviors of mothers living with their children changed during the pandemic in Japan. Ordered probit and interval regressions were applied to individual data for mothers living with children under 18 years of age from five independently conducted Surveys of Attitudes toward Food and Nutrition Education (Shokuiku in Japanese). The estimation results showed that although mothers were more likely to eat dinner with their families during the pandemic, attention to healthy dietary practices, frequency of eating nutritionally balanced food, and dietary practices for preventing lifestyle-related diseases were negatively affected by the pandemic. In conclusion, mothers were more likely to decrease their commitment to a healthy and well-balanced diet during the pandemic than before it. Further research based on the latest datasets with detailed information over the long-term is required. [ABSTRACT FROM AUTHOR]

This study examined whether the frequency of purchasing local agricultural products and the intake frequency of self-cooked meals were related to healthy eating habits. A cross-sectional study was conducted using anonymized data from the "Survey on health promotion and food-and-nutritional education" conducted in 2021 in Tamamura, Gunma, Japan, targeting residents aged 20–65. Logistic regression analyses were conducted using the purchasing frequency of local agricultural products (often/sometimes/rarely) and the intake frequency of self-cooked meals (almost every day/not every day) as independent variables. The dependent variables were the frequencies of breakfast (every day/not every day), balanced meal (two times/day or more/fewer than two times/day), and vegetable intake (two times/day or more/fewer than two times/day). The purchasing frequency of local agricultural products was positively related to the frequency of balanced meal and vegetable intake. Additionally, the intake frequency of self-cooked meals was positively related to the frequencies of breakfast, balanced meal, and vegetable intake. In conclusion, significant positive relationships of the purchasing frequency of local agricultural products and the intake frequency of self-cooked meals with healthy eating habits were confirmed.

Background: The association between neighborhood environment and health may be biased due to confounding by residential self-selection. The displacement of disaster victims can act as a natural experiment that exposes residents to neighborhood environments they did not select, allowing for the study of neighborhood effects on health.Methods: We leveraged data from a cohort of older adults 65 years of age or older living in Iwanuma, Japan, located 80 km west of the 2011 Great East Japan Earthquake and Tsunami. Surveys were conducted 7 months before the disaster, as well as 2.5 and 5.5 years afterward, and linked with medical records. We classified each individual's type of exposure to neighborhood environment based on proximity to local food and recreation destinations and walkability.Results: Fixed-effect models indicated that change in the exposure type from low to high urban density was associated with increased body mass index (0.46 kg/m; 95% confidence interval [CI] = 0.20, 0.73), waist circumference (1.8 cm; 95% CI = 0.56, 3.0), low-density lipoprotein cholesterol (11 mg/dl; 95% CI = 5.0, 17), and decreased high-density lipoprotein cholesterol (-3.1 mg/dl; 95% CI = -5.0, -1.3). We observed similar trends when we analyzed only the individuals who experienced postdisaster relocation to temporary homes.Conclusions: Increased proximity to food outlets was simultaneously correlated with greater walkability and accessibility to recreational destinations; however, any protective association of physical activity-promoting built environment appeared to be offset by proximity to unhealthy food outlets, especially fast-food restaurants and bars.

Abstract: Since 2004, research has been conducted in the Ainu Indigenous community of the Saru River Region of Biratori in Northern Japan examining traditional food use knowledge. The purpose was to improve the socio‐cultural environment for the Ainu People by implementing interventions meant to reintroduce traditional Ainu food use, so that they can live with dignity and in harmony with non‐Ainu people in the heterogeneous community where Japanese cultural values dominate. Ten years after the start of this research, a series of interviews was conducted with Ainu mothers and daughters active in the community to evaluate the result of the interventions because, in accordance with culturally established Ainu gender roles, the Ainu women prepare the Ainu dishes. The interviews indicated that the community of both Ainu and non‐Ainu people shared traditional Ainu food as a communal food at community events organized by the Ainu members of the community. The people in the community now identify traditional Ainu dishes with Ainu names, indicating the establishment of culinary and linguistic boundaries between Ainu traditional food and mainstream Japanese food. This also signals that the Ainu People have begun to establish a basis for reconstructing their unique ethnic identity, once suppressed by the government's former assimilation policy.

A parent's ability to confidently manage a child's food allergy (i.e. food allergy response capability) is considered instrumental toward treating this disorder; however, little is known regarding this measure and associated factors. A questionnaire survey among 280 qualified participants identified the greatest food allergy response capability as 'spousal collaboration', followed by 'elimination diet capacity', 'gathering information from medical professionals', 'knowledge about food allergies', and 'stress coping'. These capabilities were associated with maternal and household health status, food items eliminated and their number, anaphylaxis experience, and type of medical facility used. This measure represented a predictor of maternal quality of life and health status, household health status, and overall life stress (not related to childrearing). Thus, to improve food allergy response capability, multidisciplinary cooperation and support are required from professionals, such as physicians, nurses, nutritionists, and clinical psychologists. Nurses in particular must take an interest in the situations these mothers face and in their emotions; elicit their power to cope with stress; provide knowledge about food allergies; provide individualized, specific information about elimination diets; and conduct interventions to enable spousal cooperation.

Background: Domestication is an important and contested concept. Insects are used as food worldwide, and while some have been described as domesticated and even 'semi-domesticated', the assumptions and implications of this designation are not clear. The purpose of this paper is to explore these aspects of insect domestication, and broader debates in domestication studies, through the case of edible wasps in central rural Japan. Methods: Both authors conducted ethnographic fieldwork with communities in central rural Japan. Fieldwork comprised participant observation, semi-structured interviews, quantitative surveys and a review of resources including the personal and public records of wasp collectors. Results: The practice of keeping wasps in hive boxes has historical roots and has changed significantly within living memory. Current attempts to further develop the practice involve collectors' great efforts to keep new queens during their hibernation. Collectors have also tried, still without success, to keep wasps living within a human-made enclosure for their entire life cycle. These and other practices are costly in both time and money for collectors, who emphasise enjoyment as their primary motivation. At the same time, they also engage in practices such as pesticide use that they recognise as damaging to wasp ecology. Conclusions: These practices can be understood to some extent in domesticatory terms, and in terms of care. We develop a framework for understanding domesticatory practices of insect care, discuss how this case contributes to ongoing debates within domestication studies, and recommend further research to be pursued.

Risk characteristics within a psychometric paradigm have been of major concern in studies of food risk perception. This study compared the influence of psychometric factors, perceivers’ characteristics (i.e., risk attitude, trust, and favorability of the country of origin), and that of the news media on the levels of food risk perception. The interaction of news media with the other two factors was also examined. A nationwide survey (n = 1,500) was conducted. The foods under investigation were Chinese processed foods and Japanese seafood imported to South Korea. In both cases, hierarchical multiple regression analyses revealed that psychometric factors had the greatest influence on food risk perception, followed by perceivers’ characteristics and media use. In addition, our results showed that the effect of perceived benefit and dread in Chinese food were salient only for those with little media use. The implication of the interaction effect on food risk perception is discussed in terms of accessibility and limited capacity of information processing. [ABSTRACT FROM PUBLISHER]

Although habitual seaweed consumption in Japan would suggest that iodine intake in Japanese is exceptionally high, intake data from diet records are limited. In the present study, we developed a composition database of iodine and estimated the habitual intake of iodine among Japanese adults. Missing values for iodine content in the existing composition table were imputed based on established criteria. 16 d diet records (4 d over four seasons) from adults (120 women aged 30–69 years and 120 men aged 30–76 years) living in Japan were collected, and iodine intake was estimated. Habitual intake was estimated with the Best-power method. Totally, 995 food items were imputed. The distribution of iodine intake in 24 h was highly skewed, and approximately 55 % of 24 h values were < 300 μg/d. The median iodine intake in 24 h was 229 μg/d for women and 273 μg/d for men. All subjects consumed iodine-rich foods (kelp or soup stock) on one or more days of the sixteen survey days. The mean (median) habitual iodine intake was 1414 (857) μg/d for women and 1572 (1031) μg/d for men. Older participants had higher intake than younger participants. The major contributors to iodine intake were kelp (60 %) and soup stock (30 %). Habitual iodine intake among Japanese was sufficient or higher than the tolerable upper intake level, particularly in older generations. The association between high iodine intake as that observed in the present study and thyroid disease requires further study. [ABSTRACT FROM PUBLISHER]

This cross-sectional study aimed to investigate the association of periodontal status with occlusal force and food acceptability. We hypothesised that mastication deteriorated with reduced periodontal support, even when posterior occlusal contacts with natural teeth were maintained and the patients remained clinically asymptomatic. Participants were 482 independently living 69-71-year-olds, classified as Eichner's group A, having no mobile teeth and no periodontal symptoms. The periodontal probing depth ( PPD) and restoration status of each tooth were examined. Occlusal force in the intercuspal position was measured with pressure-sensitive films. Food acceptability was evaluated from the difficulty experienced in chewing apples, grilled beef, and hard rice crackers. Multivariate regression analysis was performed to investigate the association of periodontal status with occlusal force and food acceptability. A P-value of <0·05 was considered statistically significant. Multiple linear regression analysis showed that occlusal force had significant negative associations with maximal PPD (standardised partial regression coefficient ( β) = −0·121) after controlling for gender, handgrip strength, number of teeth, and percentage of restored teeth. Approximately 15% of participants were included in the compromised food acceptability group. Logistic regression analyses showed that compromised food acceptability was significantly associated with PPD, after controlling for gender, number of teeth, and percentage of restored teeth. Periodontal probing depth (PPD) was significantly correlated with occlusal force and self-rated food acceptability after controlling for the possible confounding factors in septuagenarians, even those with complete posterior occlusal contacts and no tooth mobility.

Objectives The aim of this cross-sectional study was to investigate the relationship of oral health status defined on the basis of presence of posterior occluding pairs ( POPs) and adequacy of removable denture fit as determined by self-report to nutrient and food intake among older Japanese. Methods The subjects were 353 Japanese aged 80 years in 2008 and were classified into four groups according to the number of POPs, defined as pairs of occluding natural, restored, or fixed prosthetic postcanine teeth (range: 0-8) and removable denture status. The groups were: (i) good dentition ( n = 56; 8 POPs and no removable prosthesis), (ii) well-fitting dentures ( n = 158; <8 POPs with self-reported good-fitting dentures), (iii) ill-fitting dentures ( n = 70; <8 POPs with self-reported ill-fitting dentures), and (iv) compromised dentition ( n = 69; <8 POPs and no removable prosthesis). Multivariable analysis of the differences in nutrient and food intake outcome variables which were collected via validated food frequency questionnaire among the four oral health status groups was conducted using general linear models. Results Intake of multiple nutrients was significantly ( P < 0.05) lower in the group with ill-fitting dentures or compromised dentition than in the good dentition group. Vegetable, fish, and shellfish consumption was significantly lower in the ill-fitting dentures or compromised dentition groups. No significant differences were seen in dietary intake between the well-fitting dentures and good dentition groups. Conclusions Dietary intake was poorer in those with self-perceived ill-fitting dentures or fewer POPs than among those having all POPs. Regular dental care to maintain intact dentition, as well as dental treatment to replace missing teeth and ensure adequate denture fit and function, may be important to the diet intake and subsequent nutritional status of older Japanese.

Data are limited on how dietary sources of energy and nutrient intakes differ among ethnic groups in the USA. The objective of the present study was to characterise dietary sources of energy, total fat, saturated fat, protein, dietary fibre and added sugar for five ethnic groups. A validated quantitative FFQ was used to collect dietary data from 186 916 men and women aged 45–75 years who were living in Hawaii and Los Angeles between 1993 and 1996. Participants represented five ethnic groups: African-American; Japanese-American; Native Hawaiian; Latino; Caucasian. The top ten dietary sources of energy contributed 36·2–49·6 % to total energy consumption, with rice and bread contributing the most (11·4–27·8 %) across all ethnic–sex groups. Major dietary sources of total fat were chicken/turkey dishes and butter among most groups. Ice cream, ice milk or frozen yogurt contributed 4·6–6·2 % to saturated fat intake across all ethnic–sex groups, except Latino-Mexico women. Chicken/turkey and bread were among the top dietary sources of protein (13·9–19·4 %). The top two sources of dietary fibre were bread and cereals (18·1–22 %) among all groups, except Latino-Mexico men. Regular sodas contributed the most to added sugar consumption. The present study provides, for the first time, data on the major dietary sources of energy, fat, saturated fat, protein, fibre and added sugar for these five ethnic groups in the USA. Such data are valuable for identifying target foods for nutritional intervention programmes and directing public health strategies aimed at reducing dietary risk factors for chronic disease.

Aim: To undertake a systematic literature review to examine the effect of food cost on diet quality and risk factors for chronic disease, specifically focusing on diet-related lifestyle diseases affecting the Australian population. Methods: A search of six databases resulted in the inclusion of one systematic review, three cohort studies, 41 cross-sectional studies and four modelling studies in this review. Results: Between 2000 and 2006, the price of healthy foods has increased more than the price of less healthy foods. Healthy Food Access Basket surveys show that a healthy diet may often be unaffordable for low- and average-income households. Diets of higher energy density were associated with lower diet cost, whereas diets of higher nutrient density and nutritional quality were associated with higher diet cost. Recent studies report an inverse association between food price and food consumption. Consequently, an increase in food cost was associated with a significant reduction in weight, waist circumference, body mass index, obesity and insulin resistance. Conclusions: Manipulation of food cost may alter food consumption and therefore risk factors for chronic disease. Further longitudinal studies investigating the impact of pricing strategies on diet quality and disease risk are needed. [ABSTRACT FROM AUTHOR]

Blonanserin is a novel potent dopamine D2 and serotonin 5-HT2 antagonist for treating schizophrenia. The aim of this study was to investigate prandial effects on systemic exposure to blonanserin in healthy volunteers, with particular attention paid to the effect of dose timing relative to meal intake. Volunteers received a single 2-mg oral dose of blonanserin under the following conditions: fasting, 30 min before eating a standard meal; or 30 min or 2 or 4 h after eating the meal. Plasma concentrations of blonanserin were measured using validated high-performance liquid chromatography coupled with tandem mass spectrometry. Ratios and 90% confidence intervals of the geometric means compared with the fasting condition indicated that the maximum concentrations of blonanserin (Cmax) significantly increased with dosing 30 min before meal intake, and 30 min and 2 and 4 h after meal intake, yielding by 330%, 239%, 272%, and 138%, respectively. The truncated area under the concentration-time curve (AUClast) also increased by 386%, 201%, 256%, and 155%, respectively. There was no difference in values of the time to reach maximum concentration between the fasting and the four fed states. Food intake increased the systemic exposure to blonanserin for all time intervals investigated in this study. The marked effect of food on the bioavailability of blonanserin should be taken into account in its dosing schedules. [ABSTRACT FROM AUTHOR]
