The Food Chain – What to eat for a better night’s sleep

Available for over a year

Many of us have our own theories about sleep. Perhaps it’s avoiding coffee after lunch, drinking chamomile tea before bed, or having a warm glass of milk. But what does the science actually say?

In this episode of The Food Chain, Ruth Alexander explores the relationship between food and sleep, asking whether changing what we eat and drink can help us get a better night’s rest.

Professor Marie-Pierre St-Onge, Director of the Center of Excellence for Sleep & Circadian Research at Columbia University, explains what decades of research have revealed about the links between diet and sleep quality. She discusses why poor sleep can change our food choices, how certain dietary patterns are associated with better sleep, and why scientists are increasingly interested in nutrients such as fibre and tryptophan.

Sleep physician Dr Allie Hare, President of the British Sleep Society, brings the perspective of the clinic. She explains the questions patients ask most often, from caffeine and alcohol to herbal remedies and sleep supplements, and discusses some of the biggest misconceptions people have about improving their sleep.

Together, they explore whether there really are “sleep foods”, what role meal timing might play, and whether social media trends and expensive supplements are distracting us from the basics.

Along the way, they answer listeners’ questions and share practical, evidence-based advice on the changes people can make today to improve their chances of a good night’s sleep tonight.
