Chrononutrition and Mental Health: Exploring Links Between Eating Patterns Circadian Rhythms and Psychological Well-being

Abstract

This study investigates the relationship between chrononutrition—timing and patterns of food intake—and mental health, focusing on how circadian rhythms influence psychological well-being. Using a qualitative approach, this literature review synthesizes recent research exploring the connections between eating patterns, biological rhythms, and mental health outcomes, such as anxiety, depression, and overall mood stability. Findings indicate that irregular eating times, late-night meals, and skipping meals disrupt circadian alignment, potentially leading to mood dysregulation and decreased psychological resilience. Conversely, eating in sync with the body’s natural circadian rhythms appears to support mental health, with regular meal timing shown to enhance mood and reduce anxiety symptoms. The review also highlights the importance of specific nutrients in promoting stable circadian cycles, suggesting that diets rich in complex carbohydrates, proteins, and certain vitamins may aid in stabilizing mood. These findings underscore the need for an integrative approach to nutrition and mental health that considers both the timing and composition of meals. This review provides valuable insights into the emerging field of chrononutrition, emphasizing the potential of circadian-aligned eating as a preventive and therapeutic strategy for mental health. Further qualitative studies are recommended to explore individualized chrononutrition interventions and their effects on mental well-being across diverse populations.
