In Japan, dietary habits have greatly changed since the coronavirus disease (COVID-19) outbreak; we examined factors related to dietary changes. An online cross-sectional questionnaire survey was conducted in November 2020 among 6000 Japanese adults (aged 20–64 years) registered with a research company and gathered data on demographics, socioeconomic factors, medical history, COVID-19 status of the respondent’s family and neighbors, fear of COVID-19, and changes in lifestyle and dietary habits since the COVID-19 outbreak. To the question “Have you made healthier changes to your dietary habits compared with the dietary habits before the spread of COVID-19 (1 year ago, November 2019)?”, 1215 (20.3%), 491 (8.2%), and 4294 (71.6%) participants answered that their dietary habits were healthier, unhealthier, and unchanged, respectively. Healthier and unhealthier dietary habits were associated with greater fear of COVID-19, altered exercise and sleep times, and smoking. Unhealthy habits were positively associated with living alone, decreasing household income, colleagues with COVID-19, stress, and weight loss/gain. Annual household income, changing household income, COVID-19 in friends, health literacy, exercise frequency, weight loss, and starting smoking were positively associated with healthier dietary changes. The generalizability of these results and strategies to inculcate healthy diets in this “new normal” should be investigated.

Appreciating food is an important concept in mindful eating, mentioned by advocates of an expanded model of mindful eating in 2016. With the exception of Japan, this concept is not common in many countries. We aimed to describe the role that appreciation for food has in the health of children from two perspectives: 1) association between children’s appreciation for food and their backgrounds, such as home and school educational experiences related to food, and 2) association between their appreciation for food and outcomes, such as attitude toward food, eating behaviors, and health status. Cross-sectional. Data were obtained from self-administered anonymous questionnaires sent to 2070 elementary school students in Tokyo, Japan, during October and December 2006. They contained several question items pertaining to the characteristics of participants: home and school educational experiences related to food, attitudes towards food (including level of appreciation for food), eating behaviors, and health status. T-test, Pearson’s correlation coefficient, and simple and multiple linear regression analyses were used to compare the total score of appreciation for food with other factors. Surveys were completed by 1994 children (response rate: 96.3%) and significant correlations were indicated by gender, educational experiences at home and school, attitudes toward healthy food, recommended food preferences, breakfast consumption, and body mass index. We concluded that appreciation for food plays an important role in children’s health.
