Biological sex and glucoregulation modulate postprandial cognition following dairy milk and fruit juice in healthy school-age children.

Recent work suggests potential postprandial benefits for cognition and on-task behavior in children, depending on the macronutrients consumed, as well as individual differences such as sex and glucoregulation. We examined the effects of 1% milk versus apple juice on cognition and on-task behavior among healthy school-age children, predicting that milk would promote better performance and a greater presence of on-task behavior compared to juice. We also examined how sex and glucoregulation influenced cognition and behavior following each beverage.

Using coffee to compensate for poor sleep: Impact on vigilance and implications for workplace performance.

Poor sleep negatively impacts vigilance and is associated with reduced well-being and work productivity. While many individuals depend on caffeine to counteract the cognitive consequences of poor sleep and restore optimal work performance, few studies have naturalistically evaluated this strategy. This study examined the effects of coffee on vigilance, comparing individuals based on recent sleep quality.
