Lay opinion vs evidence: Schlaf Ernährung

Lay opinions about sleep and nutrition are widespread: 'Cheese before bed gives you nightmares' or 'Warm milk helps you fall asleep.' The scientific evidence is mixed. Some studies suggest that certain foods like tart cherries (a natural melatonin source), kiwis, or magnesium-rich nuts may modestly improve sleep quality. However, effects are small and individual. Heavy, high-fat meals close to bedtime can disrupt sleep due to ongoing digestion. Caffeine and alcohol are well-known sleep disruptors. Overall, the evidence for specific dietary interventions to improve sleep is limited. Many claims rely on anecdotal reports or small studies. A balanced diet, consistent sleep schedule, and regular exercise are likely more impactful than isolated 'sleep superfoods.' For chronic sleep issues, medical evaluation is recommended rather than relying solely on nutrition tests or supplements.
