Anyone who has ever suffered in bed after eating three slices of pizza could surmise there is some relationship between food and sleep quality.
For Marie-Pierre St-Onge, the director of Columbia Universityโs Center of Excellence for Sleep and Circadian Research in the US state of New York, years of studying the relationship confirmed it.
Data from large-scale population studies shows that eating a lot of saturated fat and simple carbohydrates made it harder to get deep, restorative sleep, she says.
โItโs a cycle of having poor sleep leading to poor dietary choices, and lower dietary quality that further propels poor sleep,โ St-Onge says.
