Abstract
En 中文
This research addresses a critical gap in our understanding of how specific meals consumed during the day relate to cognitive function; particularly memory performance. While numerous studies have explored overall dietary patterns; few have considered the isolated effects of specific meals. Across two studies; we investigated subjective and objective measures of memory in relation to dietary habits and meal-specific consumption among adults aged 20 to 90 years. In Study 1; individuals consuming higher amounts of foods with potential adverse health effects; especially during supper; reported significantly poorer subjective memory functioning. Cheese consumption at supper emerged as the strongest predictor; with frequent cheese eaters rating their memory performance noticeably worse. Study 2 extended these findings by examining objective memory performance. Both Western-style and animal-based suppers were independently associated with poorer episodic recognition memory; with the strongest negative effects observed in younger adults. Detailed analysis revealed milk-based products and sweets as the most detrimental supper components for episodic recognition memory performance. Contrary to expectations; adherence to plant-based diet did not mitigate the negative effects of unhealthy supper choices on cognitive function. Our findings emphasize the importance of meal-specific dietary analysis. Recognizing meal-specific patterns may provide a more accurate understanding of how individual meals are associated with overall diet quality and cognitive functioning.
