The association between quality and quantity of carbohydrate with sleep, mood, anxiety, depression and stress among elderly

Our study demonstrates a strong link between carbohydrate quantity and quality (based on fiber content and glycemic load) with sleep and mental health outcomes. Higher carbohydrate quality intake as assessed by fiber content was associated with lower odds of anxiety and stress. Additionally, high carbohydrate quality intake as assessed by glycemic load was linked to improved sleep quality. These findings highlight the benefits of prioritizing high-quality carbohydrates in the diet for mental and sleep health, especially in the elderly population.
