Did you know the food choices you make day in and day out make a difference too? A growing body of research is revealing that what you eat may have a powerful influence on the quality of your shut-eye.
“We should look at diet as a way of improving sleep in those who have sleep difficulties,” says Marie-Pierre St-Onge, an associate professor of nutritional medicine and the director of the Center of Excellence for Sleep & Circadian Research at Columbia University. St-Onge and colleagues examined the cyclical relationship between sleep and diet in a review of research published in the Annual Review of Nutrition in 2021. “Of interest are foods that can improve nightly sleep outcomes, such as longer sleep duration, greater sleep efficiency (percent of time in bed spent asleep), shorter sleep onset latency (time it takes to fall asleep), and fewer awakenings at night, as well as self-reports of better general sleep quality,” they wrote in the report.
