Article Abstract
Evidence shows that supplementary snacking could provide older adults with nutrients that cannot be obtained through three meals a day. However, whether and how supplementary snacking, especially nighttime snacking, affects older adults' cognitive function remain unclear. The present study examined the effect of nighttime snacking on cognitive function for older adults. In study 1, we investigated the association between nighttime snacking and cognitive function based on data from 2618 community-dwelling older adults from the China health and nutrition survey (CHNS). In study 2, we conducted an experiment ( = 50) to explore how nighttime acute energy intake influences older adults' performance on cognitive tasks (immediate recall, short-term delayed recall, and long-term delayed recall). Both the observational and experimental studies suggested that nighttime snacking facilitated older adults' cognitive abilities, such as memory and mathematical ability, as indicated by subjective measures (study 1) and objective measures (studies 1 and 2). Moreover, this beneficial effect was moderated by cognitive load. These findings bridge the gap in the literature on the relationships between older adults' nighttime snacking and cognitive function, providing insight into how to improve older adults' dietary behaviors and cognitive function.

Study Objectives: Cortisol regulates various physiological systems and exhibits a circadian rhythm influenced by sleep-wake and light-dark cycles. The cumulative effects of consecutive night shifts and nighttime eating on cortisol dynamics are not well understood. This sub-study of a larger randomised controlled trial aimed to explore these relationships.

Shift workers have an increased likelihood of developing obesity and metabolic disorders, and the dietary intake during nighttime seems to increase the risk of these conditions. Nevertheless, it remains unclear if hunger, food preferences, and satiety differ between night workers and day workers. This study aimed to compare the daily patterns of dietary intake and subjective dietary perceptions among day and night workers.

Background: Prior research has demonstrated that pistachio intake influences gut microbiota composition; however, there has been limited investigation of pistachio-related gut microbial modulation in populations with impaired glycemia.
Objectives: The aim was to examine the effect of nighttime pistachio intake for 12 wk on the stool microbiota of adults with prediabetes [fasting plasma glucose (FPG) ≥100 mg/dL and ≤125 mg/dL].
Methods: A secondary analysis of data from a single-blind, 2-period, randomized crossover trial was conducted.

Background: The university period is an important period in which eating habits and lifestyles are shaped, digital addiction due to digital media use increases, and psychosocial changes are observed. During this period, in addition to changes university students eating behavior, unhealthy eating behavior trends such as increased night time eating behavior and increased consumption of ultra-processed foods can be observed. This cross-sectional study aimed to investigate the relationship between night eating syndrome, ultra-processed food consumption and digital addiction in university students.
