What should I know about Schlaf Ernährung?

The relationship between sleep and nutrition is bidirectional and complex. Certain nutrients like tryptophan (found in milk, bananas, oats) can promote melatonin production and improve sleep. Caffeine and heavy meals close to bedtime disrupt sleep quality. The glycemic index of the evening meal also matters: low-GI carbohydrates may aid sleep onset. However, individual responses vary, and not everyone benefits from the same foods. Deficiencies in magnesium or vitamin D have been linked to poor sleep, but evidence is mixed. Importantly, diet is just one factor – sleep hygiene, stress, and light exposure are equally critical. Most evidence comes from observational studies and mechanistic pathways; large randomized trials are lacking. Therefore, don't expect miracles from 'sleep foods' alone. A balanced diet as part of an overall healthy lifestyle is the most evidence-based approach.
