Changes in an individual’s dietary pattern can impact their sleep architecture. A meta-analysis found that high carbohydrate intake increases rapid-eye movement (REM) sleep, whereas low carbohydrate intake increases non-rapid-eye movement (non-REM sleep).[1] Also, some observational studies have found an association between increased healthy food (e.g. fruits, vegetables, fiber, seafood, and whole grains) intake and improved sleep quality.[2] In essence, consuming a balanced and nutrient-rich diet may help to optimize sleep.

Dietary patterns can significantly influence sleep architecture; high carbohydrate intake promotes rapid-eye-movement (REM) sleep and low carbohydrate intake favors non-REM sleep. Additionally, a diet rich in healthy foods like fruits, vegetables, and whole grains is associated with improved sleep quality.
