T1  - Is mindful eating sustainable and healthy?
BT  - a focus on nutritional intake, food consumption, and plant-based dietary patterns among lean and normal-weight female university students in Japan
JF  - Eating and weight disorders : studies on anorexia, bulimia and obesity
N2  - Purpose:
This study aimed to investigate the correlation between mindful eating and nutritional intake, food consumption, and healthful and unhealthful plant-based dietary patterns in young Japanese women. 

Methods:
The sample comprised 215 female undergraduates who responded to a two-questionnaire anonymous survey conducted in Tokyo, Japan in 2018 and 2019 from November to December. We measured mindful eating status using the Expanded Mindful Eating Scale (EMES) and used Japanese plant-based dietary indices to determine plant-based dietary patterns. Partial correlation analyses were conducted to determine the correlation of mindful eating with energy and nutrient intake, food consumption, and plant-based dietary patterns, after adjusting for demographics and body mass index. 

Results:
Participants with higher sub-scores in "health of the planet" and "awareness and appreciation for food" ate higher quantities of several micronutrients and plant-based foods and were more likely to have a healthful plant-based dietary pattern. They were also less likely to have an unhealthful plant-based dietary pattern. In contrast, participants with higher scores in "non-judgmental awareness" ate less protein, whole grains, and vegetables, and were likely to have an unhealthful plant-based dietary pattern. 

Conclusion:
This study is the first to show that young Japanese women with normal or lean body weight were more likely to consume healthful plant-based foods when they ate mindfully.

T1  - Later chronotype is associated with unhealthful plant-based diet quality in young Japanese women
JF  - Appetite : multidisciplinary research on eating and drinking
N2  - Background:
Having a late chronotype, that is, the tendency to go to sleep and wake up at later hours, influences an individual's physical and mental health. Despite a few studies noting the association of chronotype with healthy dietary patterns, this relationship remains unclear. 

Purpose:
This study aimed to describe the association of chronotype with healthful and unhealthful plant-based diet quality in female Japanese undergraduate students. 

Design:
Cross-sectional. 

Participants and setting:
A total of 218 female university students in Tokyo, Japan. 

Main outcome measures: 
Healthful and unhealthful plant-based dietary index-Japanese version (hPDI-J and uPDIJ), calculated using the validated brief-type self-administered diet history questionnaire. 

Statistical analyses performed:
A five-model stepwise multiple linear regression analysis was conducted. Independent variables were hPDI-J and uPDI-J scores, and dependent variables were various lifestyle habits related to the circadian rhythm and demographic characteristics.

Results:
Mean (standard deviation) sleep duration, midpoint of sleep, sleep latency time, and social jetlag were 411 (60) min, 03:56 (00:57), 21 (27) min, and 50 (39) min, respectively. Chronotype and several variables, such as residential status, energy and alcohol intake, and nutritional knowledge, were associated with healthful and unhealthful plant-based diet quality. Individuals who had higher hPDI-J scores were more likely to have an earlier chronotype (13 = -0.168, P = 0.019) and better nutritional knowledge (13 = 0.164, P = 0.022) than those with lower hPDI-J scores. Individuals were more likely to have higher uPDI-J scores if they were living alone (13 = -0.301, P < 0.001), had a later chronotype (13 = 0.181, P = 0.001), higher frequency of snacking (13 = 0.164, P = 0.019), lower total energy (13 = -0.445, P < 0.001), and worse nutritional knowledge (13 = -0.172, P = 0.001). 

Conclusion:
This study provided new evidence as to the relationship between sleep and dietary habits, the interaction of which may affect women's health.
