Wenk suggests that consuming tryptophan-rich foods, such as milk, chicken, fish, and legumes, alongside simple carbohydrates can aid the production of serotonin and melatonin to support sleep-wake cycles. He also notes that magnesium-rich foods like bananas and walnuts can assist in relaxation. Further research in chrononutrition indicates that the composition of late-night snacks may be more influential than meal timing. Consuming light snacks containing protein and fiber can stabilize glucose levels to prevent midnight awakenings. While nutrients like tryptophan, magnesium, and vitamin B6 support circadian rhythms, certain dietary choices are linked to sleep disruption. Specifically, high consumption of sugar, fats, caffeine, alcohol, and nicotine is associated with insomnia, with one study noting that regular consumption of sugary drinks is linked to a 55% higher probability of suffering from insomnia. ## Timeline ### 2026-10-31: Nutrition and sleep quality: The role of protein, fiber, and specific nutrients Dietary choices significantly impact sleep quality.
