Research by sleep professor Marie-Pierre St-Onge highlights how dietary choices significantly impact sleep quality.Her studies show that a Mediterranean-style diet, rich in fruits, vegetables, nuts, seeds, whole grains, lean proteins, and seafood, promotes deeper, more restorative sleep.Processed foods high in sugar and saturated fat disrupt sleep by causing blood sugar fluctuations and reducing deep sleep duration.

St-Onge's daily routine includes eating dinner at least three hours before bed, avoiding late-night snacks, and maintaining consistent mealtimes and sleep schedules.She also emphasizes the importance of dim lighting in the evening to support melatonin production.Her cookbook features recipes like high-fibre granola and overnight oats, which align with these sleep-enhancing principles.

The findings underscore the link between nutrition and sleep health, advising readers to prioritise whole foods and regular meal times for better rest.
